4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7  o adding precip control xx_precip  o pkg/seaice:
8  o moved ptracer ctrl index 17 -> 32   - make the (placeholder-)tracer IceAge a little more meaningful
9      by avoiding ridging of age due to convergent ice flow
10     - add diagnostics for surface temperature
11    
12    checkpoint61p
13    o eesupp (global_max & global_sum):
14     - add one more element to buffer (start at index 0) for GL_MAX/SUM output;
15     - remove starting & endding barrier (no longer needed)
16    o pkg/mdsio, writelocal:
17       works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined
18       (remove the STOP): uses shared buffer IO to store data from all threads
19       and then let master-thread write nThreads tiles.
20    o pkg/mdsio (read/write field):
21     - tiled IO done in 1 piece (all levels at a time);
22     - new header file "MDSIO_BUFF_3D.h" with 3-D buffers.
23     - multi-threaded: allow to read/write local (non-shared) array
24       (was already working with singleCpuIO ; now works also without);
25       => no longer needs barrier call after reading a file (added inside
26       mds_read/write field).
27     - move barrier calls outside gather/scatter_2d to mds_read/write_field
28    o pkg/obcs/exf
29      - exf_getffieldrec.F: add a few ". _d 0" and
30                            add code to catch the case fldperiod = 0.  
31      - obcs_precribe_read.F: change if statements so that they match
32                              the variable type (_RL)
33      - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to
34        exf_iprec) as part of namelist EXF_NML_01
35    o pkg/mdsio:
36      - read/write tiled (local) files: read/write 1-level tile chunk at a time
37        (instead of segment of length sNx); expected to speed up tiled IO.
38    o pkg/exch2:
39      - take buffer copy from/to array out of S/R exch2_send/recv into new
40        S/R exch2_put/get ; Exch of local variable now works with MPI+MTH
41        (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h).
42      - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get)
43      - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds
44        (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by
45        including Topology header file (and common blocks).
46      - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1);
47        remove 2nd exch call in exch2_s3d_rx (no longer needed).
48      - document S/R arg. list (+ update some comments)
49    o pkg/seaice:
50      - added SEAICE_CLIM_AIR code, which permits modulation of surface air
51        temperature and humidity over sea ice based on climatological values.
52      - clean up computation of Hibler+Bryan (1987) stress coupling for the case
53        of LSR (this change is expected to change the results slightly because now
54        it uses slightly difference moduli from the second last LSR solution, but
55        that is more consistent with the stress computations; this part of the code
56        is not tested in the verification experiments)
57      - fix diagnostics for flux of ice in case of B-grid
58      - turn strain rates eij and press into global fields within global
59        common block in SEAICE.h for more straighforward diagnostics
60      - fix diagnostics for principal stress components, press, zeta, eta
61        to give something meaning full
62    o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate
63      new output (all 4 tests) using default rotationPeriod.
64    o pkg KPP:
65      - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions
66      - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1
67        and normal grid from 1 to Nr)
68    o Fix computations of L4rdt in mom_calc_visc.F
69    o eesupp:
70      new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg):
71      should be called before a "stop" if we know that all process are going
72      to stop; if one Proc does call this S/R, will hang in MPI_FINALISE.
73    
74    checkpoint61o
75    o pkg/exch2: change check_depths to issue just a warning (instead of error+stop)
76    o model/src/ini_curvilinear_grid.F:
77       compute angleSin/CosC when they are not read from a file
78    o pkg/seaice:
79       add pseudo time stepping for LSOR
80    o pkg/exch2:
81       temporary fix for exch2_s3d_rx; update results of exp. hs94.cs-32x32x5.impIGW
82    o pkg/seaice:
83       Adding separate sea ice albedo, drag coefficients, and HO in Southern
84       Ocean from those in Arctic Ocean.  See *_south in SEAICE_PARAMS.h
85    o SingleCpuIO:
86       fix bug put before chkp61n (May 11), when more than 2 MPI cpu are used.
87    o pkg/seaice:
88       put exchanged variable in (local) common block for MPI+Multi-Threads
89       to work (necessary with exch1, and for now with exch2 too).
90    o verification: to get more experiments tested with mpi, mth and mpi+mth,
91      change tiling of:
92       aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
93       hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
94      update output of exp:
95       exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
96       tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
97      + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
98                       (note: output.txt generated on faulks using only 1 tile)
99    o eesupp & mdsio (SingleCpuIO):
100     - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
101       parameter "W2_useE2ioLayOut" (read from file "data.exch2").
102       Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
103     - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
104     - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
105       gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
106    o pkg/exch2:
107     - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
108       read parameter file "data.exch2" if it exists; otherwise try default regular
109       cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
110     - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
111       with new code (not to be used, just as a backup solution).
112     - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
113       in utils/exch2/input.
114    
115    checkpoint61n
116    o eesupp & mdsio (SingleCpuIO):
117      - move mapping to global io-buffer inside gather_2d/scater_2d: this save
118        memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
119        receive real*4 array (instead of real*8) to read/write 32.bit files.
120        (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
121         and remove new mapping S/R)
122    o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
123      - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
124        xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
125        when using exch2. Add S/R to map global io-buffer to global model array.
126      - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
127    
128    checkpoint61m
129    o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
130      and add 3 other S/R for other types (R4,R8,RS).
131      Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
132    o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
133     - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
134     - reduce number of macro definitions (keep only those which are used);
135       can always call directly the corrresponding S/R if needed.
136     - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
137       _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
138     Fixed wrong type of arg in:
139       atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
140       ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
141     To fix: global_sum of var in common block is wrong (multi-threaded) in:
142       dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
143     To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
144    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
145      "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
146    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
147    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
148      edges are closed (zero depth); might happen with "blank tiles";
149      for now, disabled if using OBCS.
150    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
151      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
152    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
153      to reduce length of 1.D array print in STDOUT.
154    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
155      + use 48 tiles (16x8): this will allow to test "blank tiles".
156    o start to test MPI + multi-threaded (change testreport to skip tests
157      where number of tiles do not match).
158    o genmake2: add option "-omp" to turn on Open-MP ;
159      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
160    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
161      and keep the original tile numbering. Note: compatible with old
162      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
163    
164    checkpoint61l
165    o Overlaps had been forgotten in calculating ijk keys : fixed
166    o fix cyrus makedepend for gcc 4.4
167    o experiment fizhi-cs-aqualev20:
168      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
169      and generate new output. Note: new output is much closer to the old
170      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
171      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
172    o pkg/fizhi:
173     - change to avoid indices going deliberately over array-bounds
174     - remove unnecessary MPI stuff
175     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
176     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
177       does not go over array-bounds and therefore returns reliable output.
178     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
179       this S/R has 4 output arguments, which are used inside "get_alarm";
180       when it is called with the same variable "ndum" in place of several
181       output arguments, this produces weird side effect inside "get_alarm"
182      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
183       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
184       address) and produces error.
185    o tools/gemake2: (March 27-29 2009)
186      with option "-mpi": link *_mpi files from "MODS" dir (this is what
187      testreport does).
188    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
189    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
190       update lab_sea.lsr & lab_sea.salt_plume results
191    o pkg/seaice:
192      Major overhaul of the LSOR solver: change discretization from original
193      finite differences to finite volume. The old routine is still in the
194      file seaice_lsr.F and can be turned on with the CPP-flag
195      SEAICE_OLD_AND_BAD_DISCRETIZATION
196      Along with this change, the discretization of the strain rates is changed.
197      The same flag turns on the old discretization in seaice_calc_strainrates.F
198      All verification experiments with seaice are affected (except for
199      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
200      results by setting the above flag.
201      Further changes involve changes in defaults:
202      - ALLOW_FLOODING is defined and turned on by default
203      - SEAICEadvSnow = .true. is now the default
204      - SEAICEadvSalt = .true. is now the default
205      - SEAICEadvAge  = .true. is now the default
206      - SEAICE_clipVelocities  = .false. is now the default
207                                         (as per J. Zhang's recommendation)
208      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
209        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
210      - seaice_growth: replace computation of UG by a simple copy from wspeed
211    
212    checkpoint61k
213    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
214      seaice_lsr: fixed a few metric terms,
215                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
216                  add more debugging diagnostics
217      seaice_evp: removed superfluous many metric terms of FV discretization
218                  of stress divergence
219                  affects lab_sea, lab_sea.hb87
220      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
221                  of stress divergence for non-evp solver
222                  (this part is not tested anywhere)
223      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
224                  they were effectively only half slip
225                  affects lab_sea.hb87
226      updated all relevant verification experiments (except lab_sea//output_adm.txt
227        which was left over, but fails at level 7 & 6)
228    
229    checkpoint61j
230    o pkg/seaice: turn a few hard wired parameters into run time parameters
231    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
232      time in seconds as promised by the usints in seaice_monitor and exf_monitor
233    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
234      that are not cubed-sphere grids
235    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
236    o pkg/ctrl:
237      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
238    o non-hydrostatic (calc_gw.F):
239      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
240      update output of exp. global_ocean.cs32x15.viscA4
241    o remove backward compatibility for thetaMin,phiMin
242      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
243    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
244      interpolated wind field not only for curvilineargrid=.true., but also
245      for a rotated grid (rotateGrid=.true.)
246    o pkg/exf: add capability to bypass interpolation for runoff
247      by setting yet another CPP-flag
248    o eesupp/src, B-grid exchange:
249      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
250    o autodiff
251      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
252      allows to switch to single-prec common blocks;
253      corresponding switch occurs in tamc.h, integer isbyte
254      TAF store directivs "byte" and "kind" seem equivalent;
255      Most tamc.h have been updated correspondingly.
256    
257    checkpoint61i
258    o autodiff:
259      fix autodiff_sore/_restore indices for obcs
260      (spotted by I. Hoteit, M. Mazloff)
261    o pkg/autodiff, pkg/ctrl:
262      Add flag to reduce all tapelev I/O to single-prec.
263      In data.ctrl set
264        doSinglePrecTapelev = .TRUE.
265    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
266      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
267    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
268      real fresh water flux (not yet)
269    o pkg/mdsio & rw:
270     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
271     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
272    o pkg/flt:
273     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
274       init_fixed & ini_varia.
275     - clean-up & simplify linear interpolation S/R:
276       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
277     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
278     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
279     - add vert. coordinate & horiz. indices to output files.
280     - change vertical position in initial condition, from index to depth [m].
281     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
282       (easier to get to a curvilinear grid) ; delX,delY no longer used.
283    o pkg/ggl90: a few modifications:
284     - fix bottom boundary condition, and interpolation of KappaE
285       near top and bottom
286     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
287     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
288     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
289    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
290      (maintain temporary backward compatibility, until next checkpoint)
291    
292    checkpoint61h
293    o pkg/diagnostics with "periodic averaging diagnostics":
294      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
295    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
296    o pkg/obcs: fix loop ranges for balancing code
297    o pkg/flt:
298     - improve criteria for finding which tile owns a float.
299     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
300    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
301      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
302      with ocean biogeo)
303    o pkg/flt:
304     - do some cleaning and fix the restart ;
305     - add output.txt in flt_example/results to get this pkg tested.
306    o genmake2: add an EXTENDED_SRC option and flag.
307       for now, cannot be turned on on command line (only through genmake_local)
308    o pkg/mdsio: read/write vector:
309     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
310     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
311       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
312     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
313      (drop to 4 digits matching for grad). But this test does not look very
314      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
315    
316    checkpoint61g
317    o pkg/flt:
318      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
319       + make OPTIONS file more standard.
320      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
321      - fix _BYTESWAPIO CPP-Flag
322      - standard reading of file-parameter "data.flt"
323      - fix argument list of S/R FLT_RESTART
324      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
325    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
326    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
327      a still unfixed compiler/optimization bug
328    
329    checkpoint61f
330    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
331      update results of global_ocean.cs32x15.icedyn test.
332    o move getcon.F from model/src to pkg/fizhi.
333    o pkg/exf: add parameter for extrapolation of temp up to the surface
334       and option to prevent negative evap (in bulk_largeyeager04 only).
335    o Prather Advection scheme: fix tracer conservation for divergent flow
336      (e.g., when using NonLin Free-Surface).
337    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
338    o gmredi (Visbeck-variable-K):
339     - add more parameters to Visbeck-variable-K.
340     - use a 5 points average for dSigmaR in Visbeck-K calculation
341       (more "homogenous": same stencil and same weights as in dSigmaH)
342     - update output of ideal_2D_oce experiment.
343    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
344      (#undef REAL4_IS_SLOW)
345     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
346       coordinate variable
347     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
348       (surface forcing fields), removes some of the functionality
349     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
350     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
351       probably not all: copy _RS surface flux fields to RL field before
352       calling DIAGNOSTICS_FILL
353     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
354       real*4 (CALL EXCH_*_RS) versions.
355     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
356       (generate new output).
357    
358    checkpoint61e
359    o gmredi (Visbeck-variable-K):
360      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
361      - change computation of Visbeck-K where Slope > Smax :        
362        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
363        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
364    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
365      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
366    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
367    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
368      does not become too large (to avoid precision problems in implicit-diffusion
369      solver); update ideal_2D_oce output.
370    o pkg ggl90:
371      - in ggl90_cal.F: compute only one set of visc/diff, used to
372        step forward TKE/T/S/momentum
373      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
374        have Prandlt =1)
375    o gmredi (fm07):
376      - add lower limit on Transition layer thickness + lower limit on 1/lambda
377      - allow to set few more params from data.gmredi
378    o pkg ggl90:
379          - add missing sqrt(2) factor in computation of mixing length
380            scale in ggl90_calc.F
381            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
382    
383    checkpoint61d
384    o adjoint modifs
385      - adapt to new field rhoInSitu
386      - allow to revert from StoreDynVars2D, StoreDynVars3D
387        to individual fields
388        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
389    o store 3-D (in-situ) density in commom block (DYNVARS.h)
390     - save 1 rho computation.
391     - no longer modify T & S inland when using down_slope pkg.
392    o gad_som : allow to switch to SOM advection for T & S without corresponding
393      pickup files (using new S/R: MDS_CHECK4FILE).
394    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
395      (for useSingleCpuIO to work in multi-threaded)
396    o pkg/shelfice:
397     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
398       with SHELFICEtopoFile in data.shelfice
399     - move code for reading ice shelf topography and modifying hFacC into separate
400       subroutines of the shelfice package
401     - separate initialisation of "fixed" and "variable" variables
402     - kTopC is not (yet) replaced by kSurfC, although this is possible
403    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
404    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
405      and rename:
406      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
407      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
408    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
409    
410    checkpoint61c
411    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
412      to add mass source/sink of fluid in the interior (3-D generalisation
413      of oceanic real-fresh water flux).
414    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
415    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
416    o new pkg: down_slope
417      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
418      - presently, modify T & S inland (dwnslp_calc_rho.F).
419        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
420      - implementation for ocean in P-coords not tested.
421      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
422    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
423      (to facilitate conversion of oceanic pkg to p-coordinate).
424    o change FIND_RHO to FIND_RHO_2D :
425      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
426    o new pkg: cheapaml
427    
428    checkpoint61b
429    o exch2:
430      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
431      - no longer depend on the order sequence (N,S,E,W).
432      - 3rd exchange no longer needed (tested with 24 tiles).
433      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
434      - exch_UV_A-grid readily available (but not yet tested).
435      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
436      (both are no longer needed) in exch_uv: no effect in forward run; but
437       get truncation error differences with adjoint exch.
438    o exch2:
439     - change index-bounds storage (moved from target to local tile,
440       more intuitive this way) ; rename/remove some variables.
441     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
442    
443    checkpoint61a
444    o exch2/matlab-topology-generator:
445      fix bug in index bounds for N-S internal exchange (hard to tell if this
446      had any effect on the solution).
447    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
448      is exceeded
449    o testreport: modify syntax of awk, so that it works also with
450      awk, and not only with nawk and gawk
451    
452    checkpoint61
453    o autodiff
454      Change default for TAF usage by removing argument '-nonew_arg'
455      This changes TAF subroutine argument list (ordering of active var.)
456      Omission of this flag leads to incompatibility w.r.t. TAMC
457      To restore TAMC-compatibility, need following modifs:
458      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
459      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
460      Tested TAF version is 1.9.22
461      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
462    
463    checkpoint60
464    --->>> This is the last checkpoint for which generating the adjoint
465    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
466    --->>> by default.
467    --->>> Future checkpoints will ommit this flag by default.
468    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
469    o pkg/grdchk: Add gradient check to etan0 perturbations.
470    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
471    o pkg/autodiff: more flexibility in zeroadj.
472      model/src: modifying do_oceanic_phys.F accordingly.
473    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
474    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
475      special setup of gmredi for which the adjoint is stable
476      enough for parameter optimization.
477    o bridging the gap between eddy stress and GM.
478      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
479          along with a change in CPP option (now ALLOW_EDDYPSI).
480      -> when using GM w/ GM_AdvForm:
481          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
482          is applied either in the tracer Eq. or in momentum Eq.
483          depending on data.gmredi (intro. GM_InMomAsStress).
484      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
485      The key modifications are in model/src/taueddy_external_forcing.F
486      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
487    
488    checkpoint59r
489    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
490      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
491      fix option to read coriolis(@ cell-corner) from files with CS-grid.
492    o pkg/mnc: add some attributes to standard 1D-coordinate variables
493    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
494      mass points, when using mnc for output
495      - add runtime parameter (missing_value, missing_value_int) to override
496        default (which is the value of getcon('UNDEF'))
497    o pkg/mnc: prepare mnc for the actual use of missing values with the
498      diagnostics package: small fix in mnc_cw_readwrite.template and more
499      initialisation of never used fields
500      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
501      versions
502    o pkg/thsice/thsice_ini_vars.F added default initial values so that
503      thermodynamics sea ice solver does not blow up when some initial fields
504      are missing.
505    o move from external_forcing_surf.F to ini_forcing.F
506      the p-coord. hack consisting in using pLoad to set phi0surf ;
507      update output of tutorial_global_oce_in_p (affected @ truncation level).
508    o Freshen up a bit hs94.1x64x5, notably:
509      remove rotationPeriod and tRef=5*0. (adjoint only), and add
510      exactConserv=.TRUE.
511    o pkg/generic_advdiff:
512      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
513      applies to files where Temperature & Salinity 2nd Order moments are used.
514    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
515      this uses a dynamically allocated internal state data structure
516      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
517      and requires a fortran 90 compiler
518    
519    checkpoint59q
520    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
521       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
522    o Refresh tutorial_global_oce_biogeo, notably:
523      - change bathymetry (put back seamounts in ACC, use hFacs)
524      - change EOS (POLY3 --> JMD95Z)
525      - use Bryan-Lewis vertical diffusivity
526      - use multidimensional advection
527      - remove old virtual virtual in dic pkg, now done through ptracer pkg
528      - change a couple of parameters in dic pkg
529    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
530    o pkg/obcs: change default to OBCSfixTopo = .true.,
531      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
532      - replace "debugMode" with "debugLevel .GE. debLevB"
533    o implementation of TAF directives for gchem,cfc,dic
534    o remove "exp5" (replaced by tutorial_deep_convection).
535    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
536      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
537      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
538      --> changes results in exp4, seaice_obcs
539    o tutorial_deep_convection :
540      update the set-up and increase resolution and domain size ; start
541      from pseudo initial conditions = output at t=120mn in order to see
542      something happening when running testreport.
543    o pkg/seaice: add os7mp as an advection scheme
544                  add check for advection schemes
545                  add a flag for restoring T and S underneath sea ice
546    o pkg/my82: add netcdf-support and diagnostics
547    o thsice pkg:
548      - Now hsMax limits snow height by turning it into ice following
549        flooding scheme (and now conserving energy)
550      - Slight rewriting of the formula in thsice_calc_thick.F
551      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
552      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
553    
554    checkpoint59p
555    o gchem / dic / cfc :
556      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
557      - add new parameter files: "data.dic" & "data.cfc" ;
558      - various re-arrangement in initialisation & header file ;
559      - fix tutorial_global_oce_biogeo for multi-threaded test.
560    o pkg/dic: test for "pickup_dic" file when restarting ;
561      if no pickup-file, can restart with a re-initialised pH (same as it did
562      before) providing pickupStrictlyMatch is set to False.
563    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
564      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
565    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
566      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
567    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
568     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
569       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
570    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
571       scheme to use for vorticty-term ;
572     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
573       (with default selectVortScheme, return to original discretisation)
574     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
575    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
576    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
577      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
578      also fix diagnostics VISCAHW & VISCA4W.
579    
580    checkpoint59o
581    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
582    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
583      move a few statemens out the main loop into separate loops
584    o pkg/shelfice:
585      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
586        (kg/m^2/s), does not break tests, because in verification/isomip,
587        rhoConstFresh=rhoConst (by accident)
588      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
589      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
590        new file model/src/seawater.F, so that they are available for all pkgs.
591      - convert potential temperature into in-situ temperature. This changes the
592        isomip tests => update tests
593    o add a flag writePickupAtEnd (default=true) to be able to suppress
594      writing a pickup at the last timestep
595    o tools/mpack-1.6 :
596      - disable automake (not working) and autoconf (not needed).
597      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
598        also cleaner with much less compilation warnings.
599    o pkg/profiles:
600      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
601      (for "less than 32 characters name" compiler requirement)
602    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
603      conditions that have a different sampling frequency than S/T/U/V obcs
604    o pkg/diagnostics (stats-diags):
605      - fix global Min/Max in case 1 processor get only empty tiles
606    o genmake2: replace (4 times)
607         make genmake_tc_1.o >> genmake_warnings 2>&1
608      with
609         COMM="$CC $CFLAGS -c genmake_tc_1.c"
610         echo $COMM >> genmake_warnings
611         $COMM >> genmake_warnings 2>&1
612      to make genmake2 always see the value of CC as specified in the optfile.
613    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
614      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
615      - modify verification advect_cs test to test SOM-advection on CS-grid.
616    o pkg/ctrl:
617      - Rewrite of ctrl_map_ini_ecco.F,
618        introducing a generic routine (ctrl_map_ini_gen.F).
619      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
620    
621    checkpoint59n
622    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
623      number in dedicate array "hdiag":
624      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
625        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
626      - many small changes (integer format) for large number of diagnostics
627      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
628        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
629    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
630      usingSphericalGrid, this allows to define the rotated grid coordinates
631      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
632      geographical coordinates according to the inverse of the rotation defined
633      by the Euler angles, so that Coriolis parameter and online-interpolation by
634      exf works with the geographical coordinates on XC/YC/XG/YG.
635      Naturally, this feature does not work with all packages, so some
636      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
637      profiles), because there the coordinates are assumed to be regular
638      spherical grid coordinates.
639    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
640      - introduce isopycnal diffusion coefficient control.
641    o tools/adjoint_options:
642      - additional control vector components.
643    o pkg/mnc: have mnc create marginally meaning full coordinate variables
644      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
645    o pkg/mypackage:
646      - add example of read/write pickup for state-var ;
647      - add entry points to the main code for state-vars diags & write-pickup.
648    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
649      transitions for useExfYearlyFields
650      - add new subroutine that determines the file to read from for
651        use*YearlyFields = .TRUE. and .FALSE.
652      - add a verification experiment to global_with_exf that tests
653        useExfYearlyFields with USE_EXF_INTERPOLATION defined
654    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
655      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
656      subroutines (which could be generated from a template, because they are
657      almost identical), for now they are included in obcs_prescribe_read.F for
658      simplicity
659    o pkg/exf:
660      - add a little more diagnostic to exf_interp_read (in analogy to
661        mds_read_field, can be turned off with debugLevel < debugLevA=1)
662      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
663        ugly but fast by unrolling short inner loops, inserting a unroll=8
664        directive in routine lagran, and splitting a loop and making do while the
665        outermost loop (the latter requires the intoduction of index arrays)
666    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
667    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
668      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
669    o verification/seaice_obcs: updated for restart test and latest options
670    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
671      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
672      for now this is only available for the C-grid code and also within
673      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
674    
675    checkpoint59m
676    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
677      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
678    o gad_som : fix flux output (& diagnostics) to have same units as other  
679      advection scheme fluxes (was previously multiplied by deltaT).  
680    o added verification/seaice_obcs both to test seaice open boundaries
681      and to provide an example matlab scrpt for generating them
682    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
683    o pkg/salt_plume: clean up salt_plume_frac.F to
684      remove redundancy in PlumeMethod 1 and 4
685    o pkg/kpp: added saltplume diagnostics
686    o pkg/obcs and pkg/seaice:
687      - do not set uice and vice to zero when OB*icefile are unspecified
688      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
689      - moved seaice tracer obcs after call to seaice_growth
690    o pkg/salt_plume: added various options for salt plume depth
691      criterion and for vertical distribution of the salt
692    
693    checkpoint59l
694    o pkg/ptracers: new version of ptracers pickup:
695      read meta file and write only fields which are needed to restart.
696      ( same logic as main pickup file ; also using pickupStrictlyMatch )
697    o pkg/seaice:
698      - add timescale for melting due to warm mixed layer as a means of
699        setting SEAICE_availHeatFrac more conveniently
700      - add a CPP-flag/runtime parameter check for flooding algorithm
701      - reformulated availHeat in seaice_growth.F to be independent of AREA
702    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
703      unit changes
704    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
705    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
706      SX vector computer.
707    o pkg/seaice:
708      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
709        seaice forcing fields can now be read only through pkg/exf
710      - removed some unused halos
711    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
712    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
713      or U/VICE from U/VWIND before computing U/VSTRESS
714    
715    checkpoint59k
716    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
717      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
718    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
719      all experiments pass when compile with un-initialised var. checking option.
720    o added pkg/salt_plume
721    o script to test restart (for now, in MITgcm_contrib/jmc_script)
722    o pkg/seaice: new read/write pickup version.
723      read meta file and write only fields which are needed to restart.
724      ( same logic as main pickup file ; also using pickupStrictlyMatch )
725    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
726    o lab_sea.hb87: modify the domain & update output.hb87.txt :
727      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
728      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
729      process. Fixed here by closing the domain at the Northern boundary.
730    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
731    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
732      a set of consecutive levels in/from a 3-D array.
733    o pkg/ptracers:
734      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
735      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
736    
737    checkpoint59j
738    o in pkgs: dic, obcs, offline, rbcs:
739      standard way to compute coeff. for time interpolation between 2 time reccords
740      which retains full precision (& make results less dependent on compiler).
741      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
742    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
743      packages instead of reading ice cover and wind speed separately
744    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
745     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
746      to allow to compile customized code before the update)
747    o cleaning-up:
748      - fix CPP instruction syntax in pkg/obcs
749      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
750        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
751      - fix some threads issue in IO parts.
752    o pkg/dic:
753      - add tons of "_d 0" (--> much better testreports !)
754       and then update outputs of tutorial_global_oce_biogeo
755    o pkg/mom_fluxform:
756      add a special version of momentum advection intended to conserve momentum
757      next to a bathymetry step or a coastline edge. (default = off = #undef)
758    o new read/write pickup version:
759      - for now, only implemented for main (mdsio) pickup file.
760      - write out only what is needed to restart; merge pickup_nh , pickup_ph
761        and main pickup together.
762      - read meta file; read only what is needed to restart; stop if a field
763        is missing (if pickupStrictlyMatch=T, = the default) or try to restart
764        if it make sense (even if the restart is not perfect).
765      - if no meta file, assume that pickup to read corresponds exactly to
766        a pickup that would currently be written.
767      - read pickup written in the old format (until checkpoint59i) if it
768        recognizes an old meta file (no field-list).
769      - add a meta file in exp. which starts from a pickup: 2 cases:
770        a) minimal meta file (with just file precision) + pickupStrictlyMatch=F
771         e.g.: global_ocean.90x40x15/input/pickup.0000036000.meta
772        b) a meta file describing the content of the associated pickup file
773         e.g.: tutorial_global_oce_biogeo/input/pickup.0004248000.meta
774    o pkg/mdsio & pkg/rw:
775      - new routine to read a meta file ; new set of routine to read
776        Multiple-fields file (with meta file).
777    o added open boundary conditions capability for seaice
778        HSNOW, HSALT, UICE, and VICE
779    
780    checkpoint59i
781    o adjoint:
782      * fix multiDimAdvection adjoint
783        (partial recomputation problem by TAF for fVerT(:,:,kDown)
784        and comlev1 size definition (maxpass vs. max. number of tracers)
785      * verification/global_ocean.90x45x15 adjoint now tests
786        NLFS and multiDimAdvection using DST3 (=30)
787      * verification/lab_sea now tests multiDimAdvection using DST3 (=30)
788    o pkg/kpp: add "_d 0" to real constant (if missing);
789      update output of exp: natl_box (10.digits); vermix (std, 7.digits)
790      and lab_sea, 3.FW (only 6,4,6 digits match) & AD (8.digits).
791    o prepare for "clever pickup" implementation: add new header file "RESTART.h"
792      for internal parameters related to restart process (formerly from PARAMS.h)
793      and add startAB parameter to argument list of S/R ADAMS_BASHFORTH2.
794    o more standard interface to {PKG}_WRITE_PICKUP with pickup suffix passed
795      as argument. (only atm2d & obcs write_pickup have not yet been updated)
796    o pkg/monitor:
797      - use GLOBAL_SUM_TILE instead of _GLOBAL_SUM
798      - fix mon_stats_rs (statistics over the full domain, even where field is zero)
799      - account for deep Atmosphere factor and density factor (anelastic)
800    o added open boundary conditions capability for seaice HEFF and AREA
801    o pkg/shelfice: add option for convservative form of Hellmer&Olbers (1989)
802      thermodynamics
803      - requires a little reorganization, which affects the testreport results
804        of isomip.htd (only 7 digits of cg2d agree) => update/modify experiment,
805        so that now the conservative form is tested
806      - add a few comments
807    o add missing cvs Header: or Name: in eesupp/*, pkg/* & verification/code*
808    o add a little bit of code to gad_os7mp_adv_?.F to help vectorization
809    o add new diagnostics to seaice: advective, diffusive fluxes (only for
810      multidim-advection, for scheme 2 they are not filled) and transports,
811      thermodynamic growth rates
812    o change units of EmPmR (inside the code, + within coupling interface)
813      from m/s to kg/m2/s (mass flux) but leave input file unchanged.
814      Affects results @ truncation level (cg2d match) and update output of
815       experiments: lab_sea(6), global_ocean.90x40x15(10),
816      global_ocean.cs32x15(11x3,10), natl_box(11), tutorial_global_oce_latlon(11)
817      + adjoint results: global_ocean_ebm(11) and lab_sea (12).
818      Coupled set-up: allow to restart from previous pickups (cpl_oldPickup=T).
819      Next: will retire convertEmP2rUnit (simply using mass2rUnit instead).
820    
821    checkpoint59h
822    o pkg/exf:
823      - improve vectorization by moving if-statement out of loops in
824        exf_mapfields, exf_radiation
825      - exf_bulkformulae.F: introduce 2D fields and vectorize code
826    o pkg/kpp: added the salt plume scheme (ALLOW_SALT_PLUME) to KPP package
827    o testreport:
828      - allow to test for Qnet & SeaIce monitor output; clean-up ALLOW_BULK_OFFLINE
829        monitor & update offline_exf_seaice exp. output.
830      - AD testing: pass/FAIL according to Grad. output accuracy (instead of Cost)
831    o pkg/seaice:
832      - bug fix in the evp solver: boundary conditions were affected be
833        masking of zMax/zMin (changes results)
834      - minor bug fix in boundary conditions in seaice_calc_strainrates
835        (changes results for no_slip)
836      - seaice_lsr.F: make interpolation of eta dependent on boundaries
837      - replace hardcoded lower limit for zeta (zMin) by runtime parameter
838      - add a test to lab_sea, that tests the Hibler and Bryan (1987) ocean
839        stress formulation and no-slip boundary conditions
840    o pkg/ptracers: Temporary fix for PTRACERS_useGMRedi & PTRACERS_useKPP
841      in gad_calc_rhs.F ; add few safety stops in initialisation phase.
842    o pkg/seaice: a first HSALT time stepping equation has been checked in
843    o pkg/seaice: replaced maskW with seaiceMaskU and maskS with seaiceMaskV
844      in seaice_lsr.F; this solves the pkg/seaice-pkg/obcs problem
845      without requiring DO-IF statements
846    o pkg/thsice:
847      use continuous power-law function for partition of energy between lateral
848      melting/freezing and thinning/thickening ; old code using step function
849      still available with #undef THSICE_FRACEN_POWERLAW
850      update output of exp: aim.5l_cs.thSI, global_ocean.cs32x15.icedyn & .thsice
851    o testreport: change AD testing : check against results/output_adm.txt
852      using same scripts as for forward test.
853    
854    checkpoint59g
855    o adjoint testing: in preparation for changing testreport:
856      - output format: cost and grad written on separated lines
857      - ad output results in directory "results" (instead of "results_ad")
858    o pkg/seaice: adding ice salinity HSALT as a prognostic variable
859    o pkg/seaice: changes for using pkg/seaice with pkg/obcs
860    o pkg/ecco: allow user defined cost function contributions
861    o testreport:
862      Allow to choose (per experiment) the list of tested output variables
863       and the main variable (used to issue a pass/FAIL ) ;
864      - for now, done by adding the specific list in file: [exp]/input/tr_checklist
865      - default is unchanged: >cg2d< , (T,S,U,V,5 tracers)_[min,max,mean,StD] ;
866      Also modify printing of summary:
867       a) ">" NN "<" indicates the "main" variable (used for pass/FAIL)
868       b) echo the list of tested variables in the individual summary.txt of
869          each experiment.
870    o new S/R GLOBAL_SUM_TILE to compute global sum independently of number of
871      threads and number of processes (with #define GLOBAL_SUM_SEND_RECV)
872      (but still depend on the tile decompostion of the domain).
873    o pkg/seaice: change a discretization detail to make the B-grid code
874      "more symmetric". This change is likely to remove all "ridges/leads" that
875      where quasi-aligned with the grid in B-grid solutions. It may also be
876      the solution to the stress coupling issues with the B-grid.
877    o each tested exp: add a "run" directory with a standard ".cvsignore" file ;
878      remove .cvsignore from input dir. (since testreport no longer run here).
879    o pkg/thsice:
880     - cleaning: move common block out of "THSICE_2DYN.h" (removed) to "THSICE_VARS.h"
881     - fix reshaping of sea-ice just after advection:
882       melt all the ice only if ice-volume is too small.
883     - re-visit lateral/thinning repartition of melting (modifs from May 04, 2007):
884       prevent lateral melting if sea-ice fraction is too close to iceMaskMin ;
885     and update experiment global_ocean.cs32x15.icedyn (+start from pickup files).
886    o external_forcing_surf : extend the use of salt_EvPrRn & temp_EvPrRn (fresh-water
887      tracer content) to linFS or no RealFreshWaterFlux ; default remains unchanged.
888    o define mass2rUnit & rUnit2mass as units conversion factor, used for surface
889      forcing. mass2rUnit: from mass per unit area [kg/m2] to r-coordinate unit
890      (z-coord: =1/rhoConst ; p-coord: =gravity) ; rUnit2mass is just the reverse;
891      and remove horiVertRatio (& recip_horiVertRatio). Affects truncation error
892      of exp. global_oce_in_p: 10 16 16 14 16 13 16 16 16 13 13 13 16 13 13 12 16
893      -> update output.txt
894    o pkg/cd_code: add brackets in multiple terms sum (S/R CD_CODE_SCHEME):
895     this affects truncation error: -> update output.txt of exp:
896      global_ocean.90x40x15 (fw&adm), lab_sea (fw&adm) & lab_sea.lsr,
897      ideal_2D_oce, isomip.htd, natl_box, tutorial_global_oce_latlon.
898    
899    checkpoint59f
900    o pkg/autodiff: zero_adj resets an ajoint variable to zero (in adjoint mode)
901    o pkg/ctrl: ctrl_bound  forces parameter corrections to stay in
902      a bounded range (in forward mode)
903    o pkg/ecco, ctrl, autodiff and mom_common:
904     internal parameter controls, completements of implementations
905    o add few EXCH S/R (UV_BGRID, UV_DGRID, SM) for B & D-Grid velocity & 2nd Moment Sxy.
906    o use UV_BGRID exch for dxV,dyU: for now, only with pkg/exch2 & forward ;
907      (not seem any difference in testing results).
908    o pkg/cd_code: use the right EXCH calls (for CS-grid); but problem remains
909       at face corners.
910    o pkg/generic_advdiff:
911     - in GAD.h, define as parameters (iMinAdvR,iMaxAdvR,jMinAdvR,jMaxAdvR)
912      loop range indices for computing vertical advection tendency
913      and do the calculation in the interior only (no overlap) ;
914      for now, only implemented for SOM advection (to save CPU time).
915     - add argument "withSigns" to S/R FILL_CS_CORNER_TR_RL (needed for SOM_xy moment)
916    o exch2 adjoint
917      First set of changes:
918      - add exch2 hand-written adjoint templates
919      - exch2 hand-written no longer use TAF-flag 'nownew_arg'
920        This will require cleanup in pkg/autodiff/*.F
921        (changed routines currently kept separate in verif. code/)
922      - Comment all relevant #ifndef ALLOW_AUTODIFF_TAMC
923        that used to hide exch2 or cubed-sphere specific code
924        (commented via 'cph-exch2')
925    o pkg/seaice
926      - Close southern and western boundaries for UICE/VICE when useOBCS=.TRUE.
927    o pkg/bulk_force: fix loading into Qsw of Short-Wave flux; and update
928       output of global_ocean.cs32x15.thsice .
929    
930    checkpoint59e
931    o exch2: new S/R that only use the cube-tracer (center-position) exchange:
932      for B-grid vector (not yet tested) and C-grid vector (<- only used
933      when option W2_USE_R1_ONLY in W2_OPTIONS.h is defined).
934    o starting implementation of Duffy et al. (GRL 1999) salt plume scheme
935      (#ifdef ALLOW_SALT_PLUME)
936    o gather_2d/scatter_2d: removed halo regions
937    o gmredi: add option (GM_taper_scheme='fm07') for Ferrari & McWilliams 2007
938      scheme and the corresponding test case (under front_relax dir). For now,
939      only available with Skew-flux form and not yet tested in realistic set-up.
940      adjoint: store directives updated, but gradient checks deteriorated,
941      so maybe GM/Redi adjoint is now broken.
942    o seaice adjoint
943      * add AREA, HEFF, HSNOW as control variable
944        (should not change lab_sea results)
945      * CTRL_OPTIONS.h needs new flag: CTRL_SET_OLD_MAXCVARS_40
946    o pkg/seaice:
947      * added computation of saltFlux in seaice_growth;
948        For time being, sea ice salinity is assumed constant
949        contribution of snow flooding to freshening of sea ice is neglected.
950        SEAICE_salinity is set in SEAICE_PARM01 of data.seaice and it
951        defaults to 0.0 in order to maintain backward compatibility.
952        Typical values for SEAICE_salinity are 4 to 10 g/kg.
953      * replaced dRf(1) with dRf(kSurface)*hFacC(kSurface) in seaice_growth.F
954      * added SEAICE_availHeatFrac, which specifies fraction of surface level
955        heat content used to melt or grow ice
956      * commented out cap of HICE: it helps keep ice thinner
957      * reintroduced cap of HEFF via MAX_HEFF and SEAICE_CAP_HEFF option
958      * applied OBCS T/S mask to HEFFM sea ice mask
959    
960    checkpoint59d
961    o standard name: {PKG}_DIAGNOSTICS_STATE to fill diagnostics array
962     for {PKG} state variables, and called from DO_STATEVARS_DIAGS.
963     (keep {PKG}_DIAGNOSTICS_FILL for non-state variables diagnostics)
964    o pkg/gmredi (gmredi_readparms.F): add some missing "_d 0"
965     and change default value of parameter "GM_Small_Number";
966     update output of exp: lab_sea (x2), cfc_example, global_ocean.90x40x15,
967       global_ocean.cs32x15 (x4), global_ocean_ebm, global_with_exf,  
968       tutorial_global_oce_biogeo, tutorial_global_oce_latlon
969    o pkg/ecco: cost function when applying pkg/smooth to controls
970    o pkg/ctrl: add forcingPrecond run time parameter
971    o pkg/seaice:
972     - replace ZMIN=4.e8 with ZMIN=0. in dynsolver.F as in C-grid code
973     - fix bug in metric terms of u-equation in LSR solver (implicit part),
974       changes verification/lab_sea
975     - rearrange implicit part of u-equation in LSR solver to make it easier to
976       read, understand, and debug. This causes changes at the truncation level.
977     - fix (serious) bug in the boundary conditions (sign error in the implicit
978       part) of the LSR solver. Changes all LSR results.
979     - fixed problem with HSNOW initialization to avoid thick snow when AREA
980       is initilized with small values - does not change lab_sea results.
981     - added HsnowFile initialization capability
982    o pkg/smooth: addition to model/src and pkg/ctrl so allow
983     initialization of pkg/smooth and application to control vector
984    o pkg/seaice: fix another bug in the LSR no-slip boundary conditons
985    o dependencies: pkg/profiles requires pkg/cal
986    o pkg/profiles:
987     - added option ALLOW_PROFILES_GENERICGRID
988         -> pkg/profiles can thus be used with any grid (e.g. cs32x15) assuming
989         that interpolation information (grid points and coefficients) is provided
990         within the netcdf input files.
991         -> sample matlab scripts can be found in MITgcm_contrib/gael
992         that allow you to prepare netcdf input files.
993     - also modified: cleaner include statements, cleaner error print statements,
994       cleaner stops when error, and more tests of the netcdf input files consistency.
995    o additional test (in global_ocean.cs32x15) using seaice+thsice pkgs.
996    o pkg/seaice:
997     - move seaice-diagnostics from seaice_do_diags to do_statevars_diags; this
998       requires a new routine: seaice_diagnostics_fill.F
999     - make sure that seaice does not move if not forced (pressure replacement
1000       method, Hibler and Ip, 1995), changes results
1001     - and new damping criterion for EVP solver according to Hunke, JCP, 2001
1002     - SEAICE_evpDampC = > 0. turns it on (615. is the recommended value).
1003       It is turned off by default (=-1.), because it changes the results.
1004     - make it possible to read AREA from a file, too.
1005    
1006    checkpoint59c
1007    o add S/R and diagnostics for oceanic mixed-layer depth
1008    o move GMRedi call after all vertical mixing schemes (including KPP)
1009    o pkg/thsice:
1010     - ensure iceMask > iceMaskMin : this problem appeared after May-04 modifs
1011      (melt only laterally if thin ice): update output of global_ocean.cs32x15.thsice
1012    o pkg/obcs:
1013     - bug fix for balance code
1014    o pkg/seaice:
1015      - allow values of SEAICE_elasticParm > 1
1016      - add new parameter SEAICE_evpTauRelax as an alternative
1017        to SEAICE_elasticParm
1018      - make lsr boundary conditions free slip (by default), changes result
1019      - add code for no slip boundary conditions for lsr
1020      - set minimum of zeta to zero (and not 4e8) (changes results)
1021      - add a cap on AREA after advecting AREA if seaice_growth is not called
1022    o change calculation of Visbeck K:
1023      - no longer depend on tapering scheme; instead, compute slope (limited
1024        by GM_maxSlope). this is equivalent to what was comuted before with
1025        clipping or linear tappering.
1026      - fix vertical averaging (wrong by 1/2 level)
1027      - leave the old version (but will not be maintained) within
1028        #ifdef OLD_VISBECK_CALC / #endif
1029      - update output of exp. ideal_2D_oce
1030    o change error catch in calc_r_star to improve vectorization
1031    o exf runoff and seaice: remove ALLOW_SEAICE from exf pkg files and
1032      add #define ALLOW_RUNOFF in SEAICE_OPTIONS.h (when not using exf).
1033    o adjoint:
1034      Re-organized adjoint checkpointing according to Matt Mazloff
1035      (but with modifs/completions/cleanups)
1036      Storing is now bundled into large arrays to optimized I/O
1037      (and second step in cleanup of the_main_loop)
1038    
1039    checkpoint59b
1040    o coupler (pkg/atm_ocn_coupler, pkg/ocn_compon_interf, pkg/atm2d):
1041      - export/import (between ocean & coupler) fields needed for ocean DIC.
1042    o pkg/seaice:
1043      - get rid of three more exchanges seaice_calc_viscosities (required
1044        different loop boundaries in seaice_lsr and seaice_ocean_stress)
1045      - bug fix in seaice_ocean_stress (update of lab_sea required)
1046      - reduce loop boundaries to necessary minimum also in seaice_evp
1047      - go back to the old way of computing deltaC/Z as the adjoint likes that
1048        better
1049    o Refresh of tutorial_global_oce_latlon (includes changing salinity-like
1050      passive tracer to an Age Tracer) + update output.txt
1051    o pkg/exf:
1052      - implement A-grid / C-grid selection for wind-stress input files.
1053      - clean-up exf_wind.F (remove us, use wspeed instead ; add wStress)
1054      for now, in exf_bulk_largeyeager04.F only :
1055      - change implementation for case where windspeed + 2. components wind-stress
1056        are read-in. AND use rhoConstFresh to convert evap.
1057    o pkg/seaice:
1058      - use correct EXCH_UV for wind-forcing (on A-grid).
1059      - change SEAICE_OPTIONS.h to limit the number of option combinations (regarding
1060        SEAICE_EXTERNAL_FORCING & SEAICE_EXTERNAL_FLUXES); add corresponding stops.
1061    o pkg/exf:
1062      - default EXF options are now set in EXF_OPTIONS.h (ifndef ALLOW_AUTODIFF_TAMC)
1063      EXF_INTERPOLATION:
1064      - merge global_with_exf/code version of exf_interp_read.F
1065        to the main code ;
1066      - Add new option: EXF_INTERP_USE_DYNALLOC to use Dynamical Allocation when
1067        reading the file ; Important: This options needs to be defined to recover
1068        previous code.
1069        otherwise, use fixed size array to read in (size=exf_interp_bufferSize).
1070      - no longer loose real*8 precision along the way when using exf_iprec=64.
1071    o pkg/seaice: rearrangement of common blocks (really needs more cleaning up)
1072      - change discretisation of evp-solver in order to avoid another exchange
1073        (changes lab_sea) and clean up a little
1074      - replace SQRT(MAX(deltaC,SEAICE_EPS)) by MAX(SQRT(deltaC),SEAICE_EPS)
1075        help the adjoint (this also changes the results slightly)
1076      - add a few "_d 0" where they had been missing in seaice_evp.F
1077      - cleaning up: remove unused seaice_calc_rhs.F
1078    o pkg/exf: some cleaning-up:
1079      - change various "constants" into runtime parameters
1080      - cleaned-up Large&Yeager04 routine which should eventually
1081        replace exf_bulkformulae.F (changed names of S/R and CPP)
1082        and merged various ALLOW_ATM_WIND options
1083     only used with thsice pkg (in thsice_get_exf.F):
1084      - implement fixed turbulent transfert Coeff over ice (as in Large&Yeager04)
1085        which are used when useStabilityFct_overIce=TRUE (= the default)
1086      - change default values of ice & snow emissivity and scale downward LW
1087        by ice & snow emissivity.
1088    o pkg/thsice:
1089     fix few little problems, in thsice_calc_thickn.F:
1090      - growth vertically (and not laterally) if iceFrac == iceMaskMax
1091      - melt only laterally if hIce < hThinIce (as the comments say)
1092      and in thsice_extend.F:
1093      - allow to form ice even when iceFrac == iceMaskMax (by increasing thickness)
1094      - start to form ice as soon as the minimum ice-volume is reachable.
1095     update output of test-exp: aim.5l_cs(thSI), global_ocean.cs32x15(thsice),
1096      and cpl_aim+ocn
1097    o pkg/kpp
1098     - move computation of surface related input fields to KPP into a new
1099       subroutine kpp_forcing_surf.F
1100     - remove wrong (within bi,bj loops) EXCH calls.
1101     - little cleaning (add argument myThid in last position, cvs header ...)
1102     - for now, fix conservation problem by exchanging KPPviscAz (may not
1103       be the best fix)
1104    o pkg/seaice
1105     - check for inconsistent evp parameter/cpp-flag combination
1106     - remove leftover errIO flat for obsolete name list error handling
1107    o OpenAD
1108     - changed verification/OpenAD to full baroclinic setup (including GM/Redi)
1109    
1110    checkpoint59a
1111    o pkg/seaice: some parameter clarifications and a little bit of clean up
1112    o pkg/thsice: rename run-time parameters:
1113       himin       -> hIceMin
1114       himin0      -> hThinIce
1115       hihig       -> hThickIce
1116       i0          -> i0swFrac
1117       transCoef   -> bMeltCoef
1118       frac_energy -> fracMelting
1119      add new parameters: hNewIceMax, fracFreezing, dhSnowLin
1120       with default values (for now) that do not change the results.
1121      remove old version of thsice vars advection in pkg/seaice.
1122    o in FFIELDS.h:
1123      - replace #ifndef ALLOW_EXF  by #ifndef EXCLUDE_FFIELDS_LOAD
1124      - make pLoad & sIceLoad always available (but still only used if
1125         ATMOSPHERIC_LOADING is #define).
1126    o pkg/kpp: replaced _KPP_RL with _RL
1127    o bug fixes for vertical diffusivity computations when both KPP and
1128        3D diffusivity arrays are used; pkg/kpp/kpp_calc_diff_s & _t.F
1129        are no longer updating the vertical diffusivity array
1130        (passed as argument) but are (re-) setting those arrays.
1131    o pkg/seaice: fix bug in evp solver, while doing that
1132      - change (improve?) discretization of stress computations for both
1133        cgrid-lsr and evp solver
1134      - add a new routine to compute strain rates
1135      - the above changes lab_sea results
1136      - add no slip conditions for evp solver (off by default), lsr-version
1137        may follow
1138      - fix exchange for shear at Z-points (does not change lab_sea)
1139      - retire SEAICEuseEVP, instead turn on EVP by setting SEAICE_deltaTevp
1140        (to force the user to pick a time step since there is not "safe" way
1141        of choosing it)
1142      - add principal stress diagnostics
1143      - rearrange fields for evp a little to avoid having to call a: too many
1144        exchanges and b: exchanges for stress trensor components which we do
1145        not have.
1146      - modify Hibler+Bryan (1987) stress coupling so that it reuses information
1147        of evp, complete rewrite for lsr case (latter is does not yet work
1148        in all cases)
1149    o pkg/kpp: add code to have mixing in shelf ice caverns
1150      - add myThid to all kpp routines (long overdue)
1151    
1152    checkpoint59
1153    o pkg/exf:
1154      - fix wind-stress location: defined on A-grid (if ALLOW_ATM_WIND &
1155        ALLOW_BULKFORMULAE or USE_EXF_INTERPOLATION), otherwise, defined on C-grid
1156      - move exf header files from lower_case.h to UPPER_CASE.h ;
1157        add missing cvs Header & Name
1158      - add adjoint routines and flow dirs for newly used exch_uv_agrid routines
1159      - add namelist param. selectStressGridPosition, exf_monFreq
1160      - retire many _CLIM routines, and remove data.exf_clim
1161        + params moved to data.exf
1162        + climsst, climsss now handled by exf_set_gen, i.e.
1163          climss?period=0 refers to constant field,
1164          climss?period=-12 to monthly forcing
1165      - split up namelists in data.exf
1166    o pkg/seaice:
1167      - remove seaice_exch and seaice_exch_uv
1168      - remove superfluous exchange of theta
1169      - add myThid to seaice_budget_ocean/ice
1170      - add new interface for atmospheric wind forcing (C-grid only)
1171        + new routine
1172        + two new field (taux, tauy for stress over ice)
1173        + removed one global field (DAIRN) for C-grid case only
1174    o pkg/thsise
1175      - 2nd set of modifs for thsice adjoint in conjunction with exf
1176    o enable runtime flag useEXF (useCAL is set to .T. if useEXF=.T.)
1177    
1178    checkpoint58y_post
1179    o Added capability for latitudinal dependence of Bryan and Lewis, 1979
1180      vertical diffusivity, similar to that in MOM4; turned on using
1181      #define ALLOW_BL79_LAT_VARY in CPP_OPTIONS.h and specified using
1182      diffKrBL79*, diffKrBLEQ*, and BL79LatVary in runtime data file.
1183    o Added capability for 3D specification of background vertical diffusion
1184      coefficient.  This is done by (i) #define ALLOW_3D_DIFFKR
1185      in CPP_OPTIONS.h and (ii) specifying file diffKrFile in runtime
1186      "data" file that contains the 3D vertical diffusivity coefficients.
1187    o ice dynamics (pkg/seaice) with thsice thermodynamics:
1188      - add code within pkg thsice to advect & diffuse sea-ice fields
1189      similar to (and will replace) what has been added in  seaice_advdiff.F,
1190      but: - conserving Mass, Heat & Salt.
1191           - better when using non-linear advection scheme (not yet fully tested)
1192           - can also be used in atmospheric set-up (for now, only the diffusion).
1193    
1194    checkpoint58x_post
1195    o IO option for global-file compact format:
1196      - add options when generating topology (utils/exch2/matlab-topology-generator)
1197      - add I/O capability (pkg/mdsio).
1198      - adapt utils/matlab/rdmds.m to read this format.
1199      for now long-line format not yet supported by pkg/mdsio (& exch2).
1200    o shelfice: add a few diagnostics
1201    
1202    checkpoint58w_post
1203    o p-coord. non-hydrostatic using reference profile for w <-> omega conversion:
1204      rVel2wUnit & wUnit2rVel are computed from reference profile Tref,Sref
1205      (and replace horiVertRatio in NH code).
1206      Update output of exp.: tutorial_global_oce_in_p (useNHMTerms !)
1207                         and tutorial_plume_on_slope (sensitive to truncation)
1208    o seaice: if ALLOW_ATM_WIND is undefined use wind stress
1209      directly to drive seaice model (C-grid only)
1210    o exf: when input wind-stress (#undef ALLOW_ATM_WIND):
1211     - reintroduce computation of wind from stress,
1212     - compute tau (in exf_bulkformulae.F) from windstress averaged to
1213       mass points to avoid tau = 0
1214     - fix serious bug: (1/3) in Fortran is not the same as (1./3.)
1215    o rdmnc.m: make it work with "global" files created with gluemnc
1216    o rdmnc.m : some improvements in dealing with singleton dimension
1217      (tested on all testreport mnc output files).
1218    o genmake2: disable pkg/profiles if netcdf test fails.
1219    o cpl_aim+ocn exp.: use consistent rhoConstFresh in Atm & Ocn; update output.
1220    o move call to cal_readparms up to make calendar parameters/variable available
1221      to all packages
1222    
1223    checkpoint58v_post
1224    o change EOS (from POLY3 to JMD95P) in global_ocean.90x45x15 to get
1225      useDynP_inEos_Zc tested.
1226    o pkg/exf: changes to properly interpolate/mask/scale initial fields
1227    o utils/matlab/cs_grid/read_cs: routines to speed up reading of CS510 fields
1228      and portions thereof.  See read_cs.txt for description and examples.
1229    o utils/matlab/cs_grid/bk_line: to compute transport through passages,
1230      add a script (grt_circ_bkl.m) to generate broken-line between 2 points,
1231      following the great-circle arc between those 2 points.
1232    o trap un-initialized variable with pathscale compiler on weddell.mit.edu
1233      (thanks to Constantinos): fix few problems and get (almost) all exp to pass.
1234    o 2nd-Order Moment Advection Scheme (Prather, 1986): first check-in
1235     - enable by setting #define GAD_ALLOW_SOM_ADVECT (in GAD_OPTIONS.h)
1236     - used without limiter (AdvScheme=80) or with Prather limiter (AdvScheme=81)
1237     - still needs work (not working with some options ; efficiency to improve)
1238       and serious testing.
1239     - use this scheme for temperature & salinity in 2 advection test exp.:
1240       advect_xy & advect_xz, respectively.
1241    
1242    checkpoint58u_post
1243    o new test-exp: fizhi-cs-32x32x40 (40 levels) to replace the 10 levels.
1244    o move call to INI_FORCING from PACKAGES_INIT_VARIABLES to INITIALISE_VARIA.
1245    o testreport: add option "-skipdir" to skip some test.
1246    o exf: when input wind-stress (#undef ALLOW_ATM_WIND), by-pass turbulent
1247      momentum calculation.
1248    o gad_advection: fix vertAdvecScheme (if different from advectionScheme)
1249    o some cleaning: usePickupBeforeC35 no longer supported ; remove this option.
1250      remove checkpoint.F and the_correction_step.F (no longer used);
1251      do the k loop inside CYCLE_TRACER (supposed to be more efficient).
1252    o add option (linFSConserveTr) to correct for tracer source/sink due to
1253      Linear Free surface
1254    o pkg/seaice: fix a bug in the flooding algorithm: turn off the snow machine
1255    o pkg/thsice: fix reading mnc-pickups
1256    
1257    checkpoint58t_post
1258    o pkg/diagnostics: fix multi-threaded output (when singleCpuIO=F)
1259    o pkg/mdsio:
1260     - clean-up mdsio_readfield.F & mdsio_writefield_new.F and
1261       move to new files: mdsio_read_field.F (S/R MDS_READ_FIELD) &
1262       mdsio_write_field.F (S/R MDS_WRITE_FIELD);
1263     - fix multi-threaded singleCpuIO option in MDS_WRITE_FIELD
1264     - collect old S/R  in one file: mdsio_rw_field.F (now just a call to
1265       either MDS_READ_FIELD or MDS_WRITE_FIELD )
1266     - new S/R (to replace MDSWRITEMETA), which allows to write more
1267       informations (variable names, time ...) to meta files.
1268     - modify rdmds.m to give back the meta file content.
1269    o pkg/diagnostics: change vertical interpolation to be safer, and more
1270       flexible (define p-levels to interpolate to in data.diagnostics);
1271      add argument to S/R DIAGNOSTICS_GET_POINTERS to catch the right
1272       diagnostic pointer.
1273    o pkg/seaice: more cleaning up of seaice_growth, added many comments
1274    o pkg/exf: put runoff0 and runoff1 into the appropriate common block
1275    o fix multi-category seaice:
1276     - change cpp flag SEAICE_MULTILEVEL to more meaningful name:
1277       SEAICE_MULTICATEGORY
1278     - fix short wave heat flux
1279    o pkg/seaice: change default (SEAICE_OPTIONS.h): use C-grid dynamics
1280       and allow to use EVP solver. Change forward lab_sea: test both EVP
1281       solver and LSR solver, and use C-grid dynamics (like lab_sea adjoint)
1282    o Initial check-in of lab_sea adjoint
1283      (very similar to natl_box_adjoint/code_seaice)
1284      * used C-grid and EVP solver
1285      * used KPP, GM/Redi
1286      * uses inAdExact=.TRUE.
1287      * gradient checks fail for both ADM and TLM
1288        due to sensitive snow melt code in seaice_grwoth (look for "JZ")
1289        f.d. gradients actually seem more problematic than ADM, TLM gradients;
1290        issue is related to forward mismatch between g77 an ifort
1291    o pkg/seaice: overhaul of thermodynamics
1292     - growth.F and groatb.F are replaced by new routine seaice_growth.F
1293     - budget.F is replaced by two new routines seaice_budget_ocean/ice.F
1294     - move a few global fields out of SEAICE.h into seaice_growth.F and
1295       make them 2D (FICE/QNETO/ ...)
1296     - remove FO (it is the same as QNETO)
1297     - introduce a few local fields to avoid modifying external fields such
1298       as atemp, etc.
1299    
1300    checkpoint58s_post
1301    o pkg/exf: moved exf_init_runoff.F to exf_init.F and exf_set_gen.F
1302      changed exf_set_gen.F so that
1303        genperiod=0 means input file is one time-constant field and
1304        genperiod=-12 means input file contains 12 monthly means
1305    o CG2D: use pre-computed solver main-diagonal (stored in common block);
1306      this affects truncation error ; generate new output file for exp. which
1307      fails: exp4(12d), fizhi-cs-aqualev20(12d), front_relax(10d),
1308        global_ocean.90x40x15(10d), global_ocean.cs32x15(10d).thsice(11d).viscA4(10d),
1309        ideal_2D_oce(10d), internal_wave(09d), isomip.htd(11d), matrix_example(07d),
1310        MLAdjust(4x11d,12d), natl_box(11d), rotating_tank(12d),
1311        tutorial_global_oce_in_p(10d), tutorial_plume_on_slope(11d),
1312        vermix(12d).ggl90(12d).my82(11d).opps(12d).pp81(11d)
1313    o start implementation of deep-atmosphere and anelastic formulation
1314    o verification: remove 2nd copy of input files and use script "prepare_run"
1315      to make a symbolic link to the 1rst copy (reduce downloaded size by ~81.M)
1316    o mom_common/vecinv/fluxform: fix a few initialisation isssues
1317    o profiles: fix for multithreaded case
1318    
1319    o diagnostics: rename few diags:
1320      s/'PRESSURE'/'RCENTER '/g
1321      s/'TICE    '/'oceFreez'/g
1322      s/'TAUX    '/'oceTAUX '/g
1323      s/'TAUY    '/'oceTAUY '/g
1324      s/'SWFLUX  '/'oceQsw  '/g
1325      s/DIFx/DFxE/g
1326      s/DIFy/DFyE/g
1327      and add few ocean-forcing diagnostics:
1328      atmPload, sIceLoad, oceQnet, oceFWflx, oceSflux, surForcT & surForcS
1329    o modifications to pkg/seaice/growth.F and budget.F, which change results of
1330      lab_sea experiment: HSNOW was sometimes treated as effective and sometimes
1331      as actual snow thickness.  It now refers everywhere to effective snow
1332      thickness, meaning that for non-zero AREA, actual thickness is HEFF/AREA.
1333    
1334    checkpoint58r_post
1335    o modifications to pkg/seaice/growth.F, which change results of
1336      lab_sea experiment: fixes pertain to melting snow over open water, to
1337      masking EVAP under sea ice, and to using the correct AREA variable for
1338      computations of EVAP, PRECIP, HSNOW, and GHEFF
1339    o add ability to read bathy, salt, and theta using MNC (off by def)
1340    o add flooding algorithm and advection of HSNOW for pkg/seaice;
1341      both are turned off by default and do no change any results
1342    o seaice advection with pkg/thsice: a step toward the use of non-linear
1343      advection scheme, but #ifdef or commented out for now (requires more EXCH).
1344    o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
1345      (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
1346      in natl_box (affects results @ truncation level: update output.txt)
1347    o multi-threading and IO:
1348      - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
1349      - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
1350        (needed to work with SingleCpuIO): tested in all verif. exp.
1351    o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
1352      affects the results (but none of the verification test uses this scheme).
1353    o Adding some pkg/diagnostics capability to pkg/seaice
1354      (will certainly be subject to changes)
1355    o ctrl: adding new control variables:
1356      lwflux, lwdown, evap, snowprecip, apressure, runoff
1357    
1358    checkpoint58q_post
1359    o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
1360      1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
1361      high_res_cube configuration by 4% on Columbia.
1362    o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
1363      add (in global_with_exf/code) a version of EXF_INTERP_READ without
1364      dynamical allocation (seems to work in multi-threaded).
1365    o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
1366      single CPU io) so that TAF does not have to see EESUPPORT.h
1367    o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
1368    
1369    checkpoint58p_post
1370    o obcs: stop if obcs is used with useCDscheme = .true.
1371    o shelfice:
1372     - fix a sign error so that no slip at shelfice interface works
1373     - remove stop for combination non-hydrostatic code and shelfice. That does
1374       not mean, that the results are correct, but at least they are numerically
1375       stable
1376    o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
1377    o added adjoint exch routined for all exch*3d* routines
1378      and updated flow directives
1379    
1380    checkpoint58o_post
1381    o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
1382      remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
1383    o change controling S/R for writing pickup file (new S/R do_write_pickup)
1384      and clean-up reading/writing of pickup files.
1385    o fix local version of read/write pickup (NH part) in rotating_tank/code
1386    o simplify EXCH interface:
1387     - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
1388     - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
1389    o added the regrid package
1390    o shelfice:
1391     - add a simple boundary layer scheme to reduce noise
1392     - fix the indexing in shelfice_u/v_drag so that there will be actually drag
1393    
1394    checkpoint58n_post
1395    o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to
1396       local variable (not in common block).
1397    o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass.
1398      - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more);
1399      - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
1400        to work with SingleCpuIO.
1401    o add "_d 0" to real constant of pkg/cfc subroutines ;
1402       update exp. cfc_exemple & tutorial_cfc_offline output files.
1403    o multi-threading and IO:
1404      - all threads call READ_FLD S/R (needed if using SingleCpuIO):
1405        (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
1406      - barrier before and after reading.
1407      - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
1408      - avoid using MDS_WRITELOCAL for LAND pkg output.
1409      - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
1410        common-block variables ; Allows multi-threading with master-thread IO.
1411    o change default MAX_NO_THREADS from 32 to 4 ;
1412      and stop cleanly when MAX_NO_THREADS is too small.
1413    o add S/R BAR_CHECK to check multi-threaded barrier synchronization
1414    
1415    checkpoint58m_post
1416    o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
1417       and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
1418    o make "tutorial_global_oce_latlon" from standard "global_ocean.90x40x15" exp.
1419       keep global_ocean.90x40x15 (for AD testing) with former secondary test
1420       (".qshyd") as the main test (mv output.qshyd.txt to output.txt)
1421    o CVS modules: update MITgcm_verif_basic; remove MITgcm_verif_ocean & _verif_atmos;
1422        add MITgcm_tutorials (= code + all the tutorials)
1423    o ecco, option to compute cost for total ssh (mean+anom)
1424    o consistent with addition of ptracer and ssh in pkg/profiles
1425    o profiles: adding ptracer and ssh
1426    o testreport: change multi-test output-file name
1427      (from output.txt.{name} to output.{name}.txt)
1428    o profiles: now ok for mutli-tiles case
1429    o seaice: add 4 parameters for different advection schemes for area,
1430      (effective) seaice thickness, enthalphy, and snow height. Their default
1431      is the standard parameter SEAICEadvScheme
1432    o calc_gw:
1433     - add cosFacU in zonal viscous flux (harmonic.visc.).
1434     - put back side-drag (call new S/R MOM_W_SIDEDRAG) and output.txt.
1435       of tutorial_plume_on_slope.
1436    o obcs_calc.F : fix index Pb in OBSeta & OBNeta (Thanks to Gianmaria).
1437    o calc_gw: true flux-form, account for horizontal grid spacing.
1438      update rotating_tank results, but not plume_on_slope (affected at
1439      truncation level, 11 digits).
1440    
1441    checkpoint58l_post
1442    o calc_gw:
1443     - take bi,bj loops outside calc_gw to fix Pb with local array KappaRU,V
1444     - remove side-drag for now (need to fix it); update plume_on_slope results.
1445     - fix for partial-cell & non-uniform dz; update plume_on_slope results.
1446    o commit code to make SST/SSS weights spatially variable
1447      (based on either variable in-situ or variable initial T/S weights)
1448    o pkg/ecco:
1449      * commit code to relax deviations of xx_theta, xx_salt to 5*sigma,
1450        now based on horizontally varying weights wthetaLev, wsaltLev
1451      * cost_averagesflags now returns year indices in addition to day, month
1452      * sflux balance is performed on annual basis
1453        (sflxumm, sfluxmm2, bal_sfluxmm)
1454      * for SSH anomaly, separate more cleanly contrib from T/P, ERS, GFO,
1455        including separate counting and multipliers
1456    o pkg/rbcs
1457      * add all necessary infrastructure for pkg/rbcs levN adjoint checkpointing
1458    
1459    checkpoint58k_post
1460    o testreport:
1461     - always build in dir. "build" (if not there, mkdir build instead of building
1462       & running in input)
1463     - run in dir run (if it exists), in build otherwise.
1464     - call prepare_run (if input/prepare_run exists)
1465     - run multi-threaded test (with new option: "-mth") if file input/eedata.mth exists.
1466    o pkg/exf modifications to interpolation and rotation routines for more
1467       reasonable treatment of North Pole singularity: for tracers North Pole
1468       value is set to northernmost zonal-mean value, for zonal velocity it is
1469       set to zero, and for meridional velocity it is set to northernmost value.
1470    o pkg/exf/exf_check_range.F
1471     - add tile index to diagnostics and move stop statement to the very
1472       end of the routine.
1473    o pkg/diagnostics: (diagnostics_main_init.F)
1474      define title of isomorphic variables according to the current config.
1475    o pkg/thsice with pkg/seaice dynamics:
1476    - fix domain of computation (interior only, required for exf) and do exchanges
1477    - seaice-dynamics forcing: add atmospheric and seaice loading to SSH gradient
1478    o towards a standard way of dealing with multi-threading in MONITOR
1479      and ${PKG}_MONITOR (all except ptracers_monitor) subroutines.
1480    o Pass variable viscosities (vertical and horizontal, e.g., KPP or Leith)
1481       to W momentum equation in nonhydrostatic and quasihydrostatic runs.  
1482    o make exf_monitor & seaice_monitor independant of the main (dynamics) monitor.
1483    o pkg/seaice: fix SEAICEuseEVPpickup parameter (put it in a commom block)
1484    o generic_advdiff: DST advection S/R : use local copy of velocity to compute CFL
1485       (problems ? with gradient check in bottom_ctrl_5x5 adjoint test)
1486    o tracer advection:
1487     - clean-up and simplify calc_common_factors.F
1488     - make a local copy of velocity and pass it (as u,v,r_Trans) to DST tracer
1489       advection subroutine (but still not used within DST advection S/R)
1490    o rename pkg aim_ocn_coupler to atm_ocn_coupler (later on, will be used without aim)
1491    
1492    checkpoint58j_post
1493    o new driver S/R: LOAD_FIELDS_DRIVER to load external forcing fields
1494      from file (collects calls previously in FORWARD_STEP)
1495    o move call to SEAICE_MODEL from FORWARD_STEP to DO_OCEANIC_PHYS
1496    o adjoint store dir. adjusted accordingly
1497    o genmake2
1498      replace target "ad_taf" by $(EXE_AD) ; add $(EXE_AD) to the make CLEAN list.
1499    
1500    checkpoint58i_post
1501    o pkg/seaice: add parameter that allows to scale/turn off effect of seaice
1502      on wind stress (SEAICEstressFactor defaults to 1.)
1503    o Total number of Timers is finite (<=40): comment out 2 non-essential one
1504      in the_main_loop.F to avoid Pb (e.g., when running fizhi test)
1505    o vector_invariant: fix highOrderVorticity(=4.th.Order) advection
1506      on CS-grid: no longer loosing mass.
1507    o exf & curvilinear-grid: no longer modify longitude xC & xG.
1508    o pkg/ggl90: fix sloppy output and fix a bug
1509    o pkg/seaice: added SEAICEuseEVPpickup parameter
1510      - Set to false in order to start EVP solver with
1511        non-EVP pickup files when using SEAICEuseEVP
1512      - fix sign error in diffusion in seaice_calc_rhs
1513    
1514    checkpoint58h_post
1515    * Modifications for bottom topography control
1516      o replace hFacC by _hFacC at various places
1517      o replace ALLOW_HFACC_CONTROL by ALLOW_DEPTH_CONTROL
1518      o add non-self-adjoint cg2d_nsa
1519      o update autodiff support routines
1520      o re-initialise hfac after ctrl_depth_ini
1521      o works for 5x5 box, doesnt work for global_ocean.90x40x15
1522    * Adding verification for 5x5 box (4-layer) bottom topography control
1523    
1524    checkpoint58g_post
1525    o pkg/diagnostics: implement "periodic averaging diagnostics" (e.g.,
1526       used for mean seasonal cycle, mean diurnal cycle); add an example
1527       in verification/global_ocean.cs32x15/input.thsice/data.diagnostics
1528    o pkg/ggl90:
1529      - add parameter (minimum surface kinetic energy)
1530      - fix bug (avoiding division by zero)
1531    o couple pkg/thsice to pkg/seaice:
1532      - modify advection in seaice to accomodate new scalar fields to be advected
1533      - only muliDimAdection scheme work with seaice/thsice
1534      - mapping of thsice-variables to seaice-variables, back and forth
1535      - does not break the verification experiments, but does not give the
1536        desired results either
1537    o pkg/seaice
1538      - make (default) second order advection a bit less confusing?
1539    
1540    checkpoint58f_post
1541    o couple pkg/thsice and pkg/exf (as a preparation for coupling pkg/thsice
1542      to pkg/seaice):
1543      - new routines thsice_map_exf and thsice_get_exf provide the interface
1544      - add an additional formal parameter to thsice_solve4temp
1545    o pkg/exf:
1546      - add new fields wspeed, snowprecip (to be able to couple to thsice)
1547      - correct Stefan-Boltzmann constant
1548      - new parameter for longwave surface emittance
1549      - separate some stuff from exf_bulkformulae into new routines  
1550        exf_radiation, exf_wind
1551      - add new parameters and constants: longwave emissivity for ocean, ice
1552        and snow, evaporation parameters over ice
1553      - decouple wind/stress computation from ALLOW_BULKFORMULA: always compute
1554        either wind from stress or stress from wind
1555    o pkg/thSIce:
1556    - split thsice_step_fwd.F in 2 S/R: thsice_step_temp.F & thsice_step_fwd.F
1557    - put i,j loops inside S/R: THSICE_ALBEDO, THSICE_SOLVE4TEMP, THSICE_EXTEND
1558       and THSICE_CALC_THICKN
1559    - for now, call to THSICE_GET_BULKF remains inside i,j loops.
1560    - add CPP option: ALLOW_DBUG_THSICE and header file THSICE_DEBUG.h
1561      to make debugging easier.
1562    - affects results (@ truncation level) of global_ocean.cs32x15.thsice: update output
1563    o pkg/bulk_force:
1564      - clean-up comments and parameters ;
1565      - add new Bulk-Formulae from Large and Yeager, 2004, NCAR/TN-460+STR ;
1566    o fix bug in aim+thsice albedo: snow & ice thickness arguments were switched;
1567      generate new output for test-experiment: aim.5l_cs.thSI
1568    o results_ad : rename "output.txt_adm" to "output_adm.txt" and change
1569      testreport accordingly
1570    
1571    checkpoint58e_post
1572    o SEAICE_CGRID adjoint done
1573    o R_STAR adjoint implemented.
1574      * Seems to just work (based on global_ocean.90x40x15/code_ad_nlfs/ )
1575      * need to sort out init. of h0facc, etc.
1576    o Make pkg/profile fully independent of ecco,cost, etc. stuff
1577      to be able to use it in pure forward.
1578    
1579    checkpoint58d_post
1580    o upgrade simple test-experiment to tutorial example:
1581     step.1: duplicate the experiment and (step.2) will remove the old copy.
1582      tutorial_barotropic_gyre      <- copy of exp0     (R1:barotropic_gyre_in_a_box)
1583      tutorial_baroclinic_gyre      <- copy of exp1     (R1:baroclinic_gyre_on_a_sphere)
1584      tutorial_global_oce_latlon    <- empty for now    (R1:global_ocean_circulation)
1585      tutorial_global_oce_biogeo    <- copy of dic_example
1586      tutorial_deep_convection      <- almost like exp5 (R1:nonhydrostatic_deep_convection)
1587      tutorial_plume_on_slope       <- copy of plume_on_slope
1588      tutorial_tracer_adjsens       <- copy of carbon   (R1:tracer_adjoint_sensitivity)
1589      tutorial_global_oce_optim     <- empty for now (David ?)
1590      tutorial_global_oce_in_p      <- copy of global_ocean_pressure
1591     some tutorials (R1) were already checked-in under tutorial_examples in release1_branch
1592    o correct a sign problem in cost_scat.F
1593    o obcs and ptracers: fix boundary conditions for advections schemes
1594      with larger stencil
1595    o thsice adjoint: start
1596    o mom_vecinv: add ISOTROPIC_COS_SCALING flags to mom_vi_hdissip for
1597      completeness
1598    o mom_fluxform: fixing the mutual use of ISOTROPIC_COS_SCALING
1599      and COSINEMETH_III, add comments in default CPP_OPTIONS.h
1600    o ptracers adjoint:
1601      * avoid extensive recomputatations
1602      * fix missing re-init. of gptr (missed by TAF)
1603    o obcs: add a flag (OBCSprintDiags, defaults is true) that allows
1604      me to turn off the excessive output to STDOUT that this package produces
1605    o move NH metric terms & 3.D Coriolis S/R to pkg/mom_common
1606      and add those terms in Vector-Invariant formulation.
1607    o in ctrl pkg, if ALLOW_CAL, use monthly mean controls
1608      if the control period (xx_hfluxperiod etc) is 0
1609    o in profiles pkg, clean routines and fix details
1610    o in ecco pkg, reading ssh data:
1611      fix problem in case the model does not start at iter0=0
1612    o fix mnc-pickup/restart for ptracers
1613    o new package prifiles:
1614      code to compute profile-based cost by Gael Forget
1615      (modifs in ecco, ctrl, autodiff)
1616    o Benign bug fix in initialization (spotted by M. Mazloff) of
1617      ctrl_set_globfld_xz.F ctrl_set_globfld_yz.F
1618    
1619    checkpoint58c_post
1620    o adjoint: finish NLFS adjoint and provide reference output in
1621      verification/global_ocean.90x40x15/results_ad_nlfs
1622    o seaice: add an EVP solver following Hunke and Dukowicz (1997) and the
1623      documentation of CICE. Turn on by defining SEAICE_ALLOW_EVP in
1624      SEAICE_OPTIONS.h and SEAICEuseEVP=.true. in data.seaice. Works only
1625      with SEAICE_CGRID defined.
1626    o move calendarDumps from "data" to "data.cal" and clean-up the code
1627      with a simple call to pkg/cal S/R: CAL_TIME2WRITE
1628    o add useEXF & useCAL flags (for now, set in hard-coded way)
1629    o add S/R to compute NH-metrics terms & Coriolis f' in vertical momentum
1630      (were missing in NH mode, and wrong in quasihydrostatic mode).
1631      waiting for Chris updated version of calc_gw to add those CALLs.
1632    o fix bug in quasihydrostatic S/R ;
1633      add a test for this option: global_ocean.90x40x15.qshyd
1634    o new S/R "SET_PARMS": set parameters that might depend on the use of some pkgs.
1635      (called from INITIALISE_FIXED, after INI_PARMS & PACKAGES_READPARAMS)
1636    o add on/off flag useOffLine for package OFFLINE
1637    o seaice:
1638      - modify advection so that it works also on the C-grid
1639      - extend loop ranges in seaice_lsr and seaice_dynsolver; fixes
1640        problem in multi-tile runs with C-grid
1641      - add flags for clipping ice velocities and/or masking solver forcing
1642      - fix drag (ocean on ice) formulation and a bug that caused noise in the
1643        C-grid solver
1644      - added a few comments to seaice_diffusion.F
1645      - separate C-grid and B-grid versions more cleanly (UVM and seaiceMaskU/V
1646        are now exclusive)
1647      - add a new ocean-ice stress coupling method (Hibler and Bryan, 1987) which
1648        required re-ordering the code a little:
1649       + make DAIRN global variable (defined in SEAICE)
1650       + move computation of the viscosities eta and zeta into a new separate
1651         routine (because I need to recompute them in seaice_ocean_stress.F)
1652    
1653    checkpoint58b_post
1654    o AIM+thSIce: fix sign of Short-Wave through the Ice ;
1655      update output.txt of exp. aim.5l_cs.thSI
1656    o various mnc cleanups and improvements:
1657      + shrink lookup tables by factor of ~4
1658      + better error reporting when running out of lookup space
1659      + able to handle longer path/file names (up to 500 chars)
1660    o adjoint:
1661      - Another overhaul of store dirs. for NLFS to eliminate  "hidden" recomputations.
1662      - TBD: "hidden" mom_vecinv recomp. in dynamics
1663    o change forcing_In_AB to affects both T,S forcing and Momentum forcing
1664     (allow to differentiate between forcing components using new integer flags:
1665      momForcingOutAB=1/0 & tracForcingOutAB=1/0)
1666     and add new flag to put Dissipation tendency out of Adams-Bashforth.
1667    o ecco
1668      - enable trend removal from SSH anomaly obs.
1669    o adjoint
1670      - a fix for PmEpR when #undef EXACT_CONSERV
1671      - fix of "hidden" recomp. in thermodynamics (no TAF warnings)
1672      - try to fix "hidden" recomp. in forward_step for NLFS
1673        (NLFS seems broken sometimes after I checked it in)
1674    o seaice:
1675     - add c-grid version of the dynamic solver:
1676       + three new routines that are the c-grid substitute lsr, dynsolver
1677         and ostres
1678       + put a few fields that were local to dynsolver into global common
1679         blocks, so that I can move the computation of stresses etc into
1680         seaice_lsr (saves coding but may break the adjoint).
1681     - replace more hardwired parameters by runtime parameters
1682     - add ice masks that mask the rhs of the implicit solvers where there
1683       is no ice (commented out in seaice_dynsolver, because i am not sure
1684       if this works properly), eventually this should replace the clipping
1685       of ice velocities in seaice_dynsolver to +/-40cm/s.
1686    o remove the BUILD_INFO.h include from CPP_EEOPTIONS.h and explicitly
1687      include it only where its needed
1688    o move balancing of fluxes before the call of external_forcing_surf
1689    o seaice:
1690      - correct units of turning angles (now they are really in degrees)
1691      - move computation of GWATX/Y out of main routine into dynsolver
1692      - initialize GWATX/Y in seaice_init
1693    o Apply mask on Fresh-Water flux (needed for SSH forcing).
1694      update output.txt of exp. global_ocean_ebm & cpl_aim+ocn (affects cg2d residual)
1695    o seaice: add runtime flags for turning angles (default to zero)
1696    o Adding runtime parameter to exf/, ctrl/, to remove on-the-fly global mean
1697      and trend from exf forcing and ctrl control adjustments
1698    o fix variable aliasing in gad_calc_rhs that cannot be handled by TAF
1699      (since checkpoint57x_post)
1700    o change the default rotation period to 86164.s = the Earth rotation
1701    o 1rst implementation of Implicit IGW using the 3-D solver (use3Dsolver=T)
1702      and based on a reference stratification. Tested within hs94.cs-32x32x5.
1703    o seaice advection: add code for choosing between the default (2nd order
1704      central differences) and multiDim advection schemes provided by
1705      pkg/generic_advdiff
1706    o seaice:
1707      - removed all references to SEAICE_GRID.h fields from
1708        dynsolver, advect, diffus, lsr, without changing the results of lab_sea
1709        (cubed-sphere configuration will change a little)
1710      - grid computations in seaice_init are obsolete now.
1711      - cleaned up code a little so that is easier to read (hopefully).
1712      - added new (better?) discretizations of default advection and diffusion
1713        (turn on with SEAICEuseFluxForm)
1714      - replace 1 in 3d global fields by kSurface in growth.F
1715      
1716    checkpoint58a_post
1717    o seaice:
1718      - bug fix in advect.F
1719    o shelfice:
1720      - separate shelfice load anomaly from pload (breaks with time
1721        dependent forcing), => introduce constant field shelficeLoadAnomaly.
1722        Its default is 0., but it may be computed more cleverly from (unknown)
1723        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
1724        done offline. A good approximation of the pressure load anomaly is
1725        necessary to avoid large initial adjustment processes underneath
1726        deep-reaching shelfice.
1727      - small fix in ISOMIP shelfice_thermodynamics
1728      - add more sophisticated thermodynamics of Hellmer (1989), this is
1729        now the default
1730      - give a few constants more intuitive names
1731    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
1732      if bulk formulae are used in long integration (especially EmPmR). Turn
1733      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
1734      if balancePrintMean, the imbalance that is substracted is printed to
1735      STDOUT.
1736    o fix bug (typo) in obcs_apply_eta.F
1737    o add a new package shelfice which enables us to model the circulation
1738      underneath shelf-ice with draughts of hundreds of meters.
1739     - works
1740     - to do: + include improved thermodynamics
1741              + check whether kSurfC (from model/inc/SURFACE.h) can be used
1742                instead of new field kTopC
1743              + can we use topoFile, Ro_surf and existing code in ini_depth.F
1744                instead of new field R_shelfIce and new code in ini_depth.F
1745                and ini_mask_etc.F?
1746              + adjust vertical mixing schemes?
1747    o seaice pkg:
1748     - add a cpp-flag to include a simple formula for a salinity dependent
1749       freezing point of sea water at the surface
1750     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
1751       meridional stresses are now different (and hopefully correct)
1752    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
1753       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
1754       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
1755    o pkg/diagnostics: add options and parameters for regional-statistics
1756       diagnostics ; define regions by reading a region-mask from a file
1757       (might add other options later)
1758    o pkg/bulk_force:
1759     - add option and parameters to use AIM surface-flux formulae.
1760     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
1761       others forcing fields (defined in PARM05, parameter file "data") are loaded
1762       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
1763     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
1764     - use the right EXCH call for uwind,vwind (to work on CS-grid).
1765     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
1766       and parameters (note: calcWindStress replaces .NOT.readwindstress).
1767     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
1768    
1769    checkpoint58
1770    o add "--embed-source" option to genmake2 which, when the supporting
1771      tools can be compiled (as determined by genmake2) will turn on the
1772      embed_files package which then embeds the entire MITgcm source code
1773      (*.[fFhc] + Makefile) used for the build within the executable
1774      - requested by CNH but off by default
1775      - adds a paltry <9MB to the mitgcmuv executable in most cases
1776      - only writes the output when useEMBEDSRC in eedata is true
1777    o clean up 3-dim. relaxation codes:
1778      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
1779      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
1780      * Thanks to Tom Haine for testing!
1781    
1782    checkpoint57z_post
1783    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
1784      affects output (@ truncation level) of exp. plume_on_slope ; updated.
1785    o fix the pickup behavior for obcs in combination with ptracers
1786    o fix a bug in ptracers_external_fields_load
1787    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
1788      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
1789    o transfered surface NH pressure to eta field (if exactConserv).
1790    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
1791         and update lab_sea output.txt file.
1792    o completing 3-dim. relaxation code: additional term
1793         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
1794      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
1795      * At compile time, in "EXF_OPTIONS.h" set
1796          #define  ALLOW_CLIMTEMP_RELAXATION
1797          #define  ALLOW_CLIMSALT_RELAXATION
1798      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
1799          tauThetaClimRelax3Dim = 15552000.0,
1800          tauSaltClimRelax3Dim  = 15552000.0,
1801      * 3 cases:
1802          1) Use a constant-in-time 3-dim. field
1803          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
1804          3) Real-time relax. to time-evolving prescribed field
1805    o Adding Laplacian-type smoothness constraint on
1806      initial and boundary (forcing) controls (ic, bc)
1807      * enable at compile-time via
1808        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
1809      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
1810      * Absolute scale somewhat unclear so far
1811      * no area weighting was included since no other cost term does so far
1812    
1813    checkpoint57y_post
1814    First step for a NLFS adjoint
1815    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
1816    o new init. routines for calc_r_star, calc_surf_dr
1817    o still need to deal with ini_masks_etc
1818    o testreport seemed happy
1819    checkpoint57y_pre
1820    
1821    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
1822    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
1823    o add new offset feature to offline pkg (plus minor cleanup)
1824    o cfc fixes for final year of integration
1825    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
1826      be in GCHEM_OPTIONS).
1827    
1828    checkpoint57x_post
1829    o fix testreport Pb in multiple test experiment.
1830    o cleanup our namelist syntax in verification:
1831      - make it more F95 standards compliant (some work still needed)
1832      - allows the vast majority of our tests to work with gfortran
1833    o Non-Hydrostatic:
1834     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
1835     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
1836    o Allow to apply AB on T,S rather than on AB(gT,gS):
1837     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
1838     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
1839       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
1840     - need a "clever" read_pickup to restart from the other AB formulation
1841    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
1842    o remove some unused variables (reduces number of compiler warnings)
1843    o adjoint
1844      * Disable useVariableViscosity for adjoint for time being
1845        (there are a number of extensive recomputations)
1846      * Initialize certain variables needed for adjoint
1847    
1848    checkpoint57w_post
1849    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
1850                 fix the singleCpuIO RS version of MDSWRITEFIELD
1851       and add a WARNING if using globalFiles=T with multi-processors.
1852    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
1853      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
1854    o tracer advection scheme:
1855      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
1856       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
1857       was not very convenient).
1858      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
1859       (further tests needed for the implicit DST & Flux-Limiter schemes).
1860    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
1861      and sRef for convenience, handy, when you want to initialize
1862      ptracers in a large domain with a constant non-zero value. Also,
1863      untangle ptracers_init.F a little.
1864    
1865    checkpoint57v_post
1866    o change dome exp. to use variable viscosity in side-drag terms.
1867    o remove all the files from the cfc_offline test since they are now
1868      incorporated into tutorial_cfc_offline which has been producing
1869      identical results for a few days of testing
1870    o add new parameter: sideDragFactor to enable half-slip-side BC
1871      and change side-drag S/R to use viscosity from mom_calc_visc
1872      (can switch back by setting sideDragFactor=0.); affects results at
1873      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
1874       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
1875    o vorticity & strain are now computed without masking, to account for
1876      no-slip-side BC in variable viscosity calculation ; mask is applied
1877      anyway later on, before computing advection/coriolis terms.
1878    o modify exp4 to test new obcs support for reading from external files
1879      and for passive tracers
1880    o fix behavior of ptracers_monitor when monitor output is written to a
1881      netcdf-file; still not independent of monitor.F (writes in the same
1882      file).
1883    o change default value of tRef (put a uniform, meaningful value for ocean
1884      & atmos) and initialize sRef (was missing, as Martin mentioned).
1885    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
1886      to be proportional to enstrophy dissipation length.  Thus,
1887       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
1888      This is now consistent with Smagorinsky and with the manual.
1889    
1890    checkpoint57u_post
1891    o OBCS and PTRACERS: add open boundary support for passive tracers
1892      - either use homogenous (pseudo) v.Neumann conditions or prescribe
1893        OB-values from file; this is not different from the way theta and salinity
1894        are treated
1895      - however, Orlanski-radiation conditions are not supported, and the model
1896        will stop if you use pTracers and Orlanski at the same time.
1897      - beefed up the rountine obcs_external_fields_load: now only those open
1898        boundary values are overwritten with values from files for which there
1899        are really files, otherwise the OB-fields remain untouched. This makes
1900        it possible to use different OBs at different ends of the domain (as
1901        with EXF)
1902    o reduce number of exch calls in shap_filt (s2).
1903    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
1904      truncation level) 4/5 MLAdjust test results (11&12 digits match).
1905    
1906    checkpoint57t_post
1907    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
1908    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
1909      same truncation, independent of the face number: affects affects several
1910      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
1911    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
1912      note that biharmonic viscosity + no-slip was not tested in any experiment.
1913    o fix bug in non-linear free-surf side-drag ; generate new output for
1914      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
1915    o make mnc honor the writeBinaryPrec flag for most kinds of output
1916    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
1917    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
1918      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
1919    o add brackets in multi-terms sum to get same truncation, independent of
1920      the face number (manage to get exactly same value of gU,gV at the cs-edge)
1921      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
1922    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
1923      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
1924      a maximum grid-scale Reynolds number.  Also, changes all length calculations
1925      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
1926      Suggested values of viscosity parameters found in mom_calc_visc.
1927      Many new viscosity diagnostics available.
1928    
1929    checkpoint57s_post
1930    o Add clearing-house for viscosity calculations, mom_calc_visc and
1931      correct numerous bugs in LeithD and Smagorinsky discretizations.  
1932      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
1933      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
1934      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
1935      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
1936      The Strain-Tension form is now called with useStrainTensonVisc=.true.
1937      ViscAhStrain and viscAhTension are now retired.
1938    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
1939    o In response to JMC's bug report, genmake2 now ignores any soft-links
1940      that it finds in the *current* directory when searching for files.
1941      Soft-links found in any other source directories will still work as
1942      they did before.
1943    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
1944      a C routine to unlimit the stack size
1945    o mnc-ify pkg/aim snapshot vars
1946    o mnc-ify pkg/land as requested by Daniel
1947    o various changes to mnc including:
1948      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
1949      - output can now be grouped so that all files within a group
1950          change the ITER portion of their names in lock-step together
1951      - can now read ("global") PER-FACE (in addition to PER-TILE) files
1952          and works with both EXCH1 and EXCH2 (but needs more testing)
1953      - writing works for all verification test cases w/ g77 on Linux
1954    
1955    checkpoint57r_post
1956    o make MNC variable initialization happen earlier
1957    o add diagnostics for (almost) each term of the momentum Eq.
1958    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
1959    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
1960    o remove MINIMAL_TAVE_OUTPUT option ;
1961      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
1962    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
1963      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
1964    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
1965    o add time-dependent SST, SSS control
1966    o cost terms in ecco/ modularized (new cost_generic.F)
1967    o cost_averages routines are modularized (new cost_averagesgeneric.F)
1968    o new infrastructure for seaice model vs. obs misfits in seaice/
1969      * driver from the_main_loop.F is seaice_cost_driver.F
1970      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
1971      * gradient check in Exp. 6a of natl_box_adjoint/
1972    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
1973      (see README file)
1974    
1975    checkpoint57q_post
1976    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
1977    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
1978      - bug was reported by Jean-Michel and Ian Fenty
1979    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
1980      update exp. cpl_aim+ocn output.
1981    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
1982      Needed for high-res. runs with large global files
1983      to be able to limit tapelev size
1984    o Changed some tests for adjoint:
1985      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
1986      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
1987      * global_ocean.90x40x15/ back to default 3-level checkpointing
1988    o Modifications to enable scripted COMMON to MODULE conversion
1989      * verification/OpenAD/code/ has necessary scripts and description;
1990      * converts, compiles and runs successfully;
1991    
1992    checkpoint57p_post
1993    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
1994    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
1995      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
1996    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
1997    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
1998      (was already the case for dissipation with mom_vecinv,
1999       and also the case for grad.PhiHyd when staggered-timeStep)
2000      This will allow to put dissipation out-off the AB time-stepping.
2001     Unfortunately, affects truncation error. Update output of exp. that "fails"
2002      (cg2d matching number) and leave the others for later: front_relax(10),
2003      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
2004      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
2005    
2006    checkpoint57o_post
2007    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
2008      (2) its ready to be documented during the 20050801 DocFest
2009    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
2010      for ideal_2D_oce and lab_sea on linux_ia32_g77
2011    o set to #undef CTRL_SET_OLD_MAXCVARS_30
2012      in global1x1_tot/code_seaice_adj to access indices 32, 33
2013      (worth another tag)
2014    
2015    checkpoint57n_post
2016    o adding precip control xx_precip 32
2017    o adding swflux control xx_swflux 33
2018    o Replacing 10 forcing penalty cost routines by 1 generic.
2019    o Implementing partitioning in time-mean and variable adjustment
2020      for atmos. state.
2021    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
2022  o in natl_box_adjoint:  o in natl_box_adjoint:
2023    * updated: results_bulk/    * updated exp 1 to 10
2024    * not yet updated: results/, results_seaice/      (but does not have time-mean vs. variable split results yet)
2025    o updated global1x1/*_seaice_adj/
2026      to incorporate latest changes
2027    o enable useSingleCpuIO for mdsio vector routines
2028      (applies in particular to tapelev I/O)
2029    o removed inefficient K-loop in all active_file*control*.F
2030
