4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi
8    o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
9    o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
10      edges are closed (zero depth); might happen with "blank tiles";
11      for now, disable if using OBCS.
12    o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
13      link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
14    o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
15      to reduce length of 1.D array print in STDOUT.
16    o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
17      + use 48 tiles (16x8): this will allow to test "blank tiles".
18    o start to test MPI + multi-threaded (change testreport to skip tests
19      where number of tiles do not match).
20    o genmake2: add option "-omp" to turn on Open-MP ;
21      passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
22    o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
23      and keep the original tile numbering. Note: compatible with old
24      W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.
25    
26    checkpoint61l
27    o Overlaps had been forgotten in calculating ijk keys : fixed
28    o fix cyrus makedepend for gcc 4.4
29    o experiment fizhi-cs-aqualev20:
30      switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
31      and generate new output. Note: new output is much closer to the old
32      one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
33      the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
34    o pkg/fizhi:
35     - change to avoid indices going deliberately over array-bounds
36     - remove unnecessary MPI stuff
37     - perpetual spring equinox with "#define FIZHI_USE_FIXED_DAY"
38     - new version of S/R GETPWHERE available with #define TRY_NEW_GETPWHERE:
39       does not go over array-bounds and therefore returns reliable output.
40     - in fizhi_driver.F & fizhi_turb.F, fix "get_alarm" calls:
41       this S/R has 4 output arguments, which are used inside "get_alarm";
42       when it is called with the same variable "ndum" in place of several
43       output arguments, this produces weird side effect inside "get_alarm"
44      (e.g., datein=dates(n) is overwritten by timein=times(n) since both
45       datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
46       address) and produces error.
47    o tools/gemake2: (March 27-29 2009)
48      with option "-mpi": link *_mpi files from "MODS" dir (this is what
49      testreport does).
50    o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
51    o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
52       update lab_sea.lsr & lab_sea.salt_plume results
53    o pkg/seaice:
54      Major overhaul of the LSOR solver: change discretization from original
55      finite differences to finite volume. The old routine is still in the
56      file seaice_lsr.F and can be turned on with the CPP-flag
57      SEAICE_OLD_AND_BAD_DISCRETIZATION
58      Along with this change, the discretization of the strain rates is changed.
59      The same flag turns on the old discretization in seaice_calc_strainrates.F
60      All verification experiments with seaice are affected (except for
61      seaice_exf_offline); global_ocean.cs32x15/input.icedyn recovers the old
62      results by setting the above flag.
63      Further changes involve changes in defaults:
64      - ALLOW_FLOODING is defined and turned on by default
65      - SEAICEadvSnow = .true. is now the default
66      - SEAICEadvSalt = .true. is now the default
67      - SEAICEadvAge  = .true. is now the default
68      - SEAICE_clipVelocities  = .false. is now the default
69                                         (as per J. Zhang's recommendation)
70      - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
71        is defined, SEAICE_TEST_ICE_STRESS_1 is renamed into SEAICE_BICE_STRESS
72      - seaice_growth: replace computation of UG by a simple copy from wspeed
73    
74    checkpoint61k
75    o pkg/seaice: a few bug fixes mostly concerning the metric terms:
76      seaice_lsr: fixed a few metric terms,
77                  affects lab_sea.lsr, lab_sea.salt_plume, seaice_obcs
78                  add more debugging diagnostics
79      seaice_evp: removed superfluous many metric terms of FV discretization
80                  of stress divergence
81                  affects lab_sea, lab_sea.hb87
82      seaice_ocean_stress: removed superfluous many metric terms of FV discretization
83                  of stress divergence for non-evp solver
84                  (this part is not tested anywhere)
85      seaice_calc_strainrates: fixed a bug in no-slip boundary conditions,
86                  they were effectively only half slip
87                  affects lab_sea.hb87
88      updated all relevant verification experiments (except lab_sea//output_adm.txt
89        which was left over, but fails at level 7 & 6)
90    
91    checkpoint61j
92    o pkg/seaice: turn a few hard wired parameters into run time parameters
93    o pkg/seaice/exf/monitor: turn netcdf coordinate variable T into model
94      time in seconds as promised by the usints in seaice_monitor and exf_monitor
95    o pkg/mnc: fix the coordinate variables for multi-tile curvi-linear grids
96      that are not cubed-sphere grids
97    o pkg/seaice: fix a bug for the rare case of SEAICE_VECTORIZE_LSR
98    o pkg/ctrl:
99      fix bug in ctrl_depth_ini.F (EXCH_XYZ was applied to 2-D field xx_r_low)
100    o non-hydrostatic (calc_gw.F):
101      fix viscA4 on CS-grid + fix diagnostics: Wm_Diss & Wm_Advec
102      update output of exp. global_ocean.cs32x15.viscA4
103    o remove backward compatibility for thetaMin,phiMin
104      (replaced by xgOrigin,ygOrigin on Jan 27, 2009)
105    o pkg/exf: fix a serious bug in exf_set_uv.F: do a rotation of the
106      interpolated wind field not only for curvilineargrid=.true., but also
107      for a rotated grid (rotateGrid=.true.)
108    o pkg/exf: add capability to bypass interpolation for runoff
109      by setting yet another CPP-flag
110    o eesupp/src, B-grid exchange:
111      add simple (6 tiles, non MPI) CS exch + standard interface S/R.
112    o autodiff
113      new CPP option ALLOW_TAMC_SINGLEPREC_COMLEV
114      allows to switch to single-prec common blocks;
115      corresponding switch occurs in tamc.h, integer isbyte
116      TAF store directivs "byte" and "kind" seem equivalent;
117      Most tamc.h have been updated correspondingly.
118    
119    checkpoint61i
120    o autodiff:
121      fix autodiff_sore/_restore indices for obcs
122      (spotted by I. Hoteit, M. Mazloff)
123    o pkg/autodiff, pkg/ctrl:
124      Add flag to reduce all tapelev I/O to single-prec.
125      In data.ctrl set
126        doSinglePrecTapelev = .TRUE.
127    o model/src/ini_curvilinear_grid.F, new grid-file format without EXCH2:
128      check in hack for SX8 compiler (for dxV, dyU); remove it afterwards.
129    o pkg/shelfice: fix bug with SHELFICEconserve flag, prepare for
130      real fresh water flux (not yet)
131    o pkg/mdsio & rw:
132     - add argument & option to S/R MDS_WRITEVEC_LOC (avoid Open/Close & write-meta)
133     - add simple interface S/R to MDS_WRITEVEC_LOC in pkg/rw: WRITE_GLVEC_RX.
134    o pkg/flt:
135     - replace FLT_INIT by 3-steps standard initialization S/R: readparms,
136       init_fixed & ini_varia.
137     - clean-up & simplify linear interpolation S/R:
138       move flt_bilinear.F -> flt_interp_linear.F ; add arg. myThid.
139     - fix some indices (mainly vertical index) ; add IMPLICIT NONE.
140     - more efficient I/O, using new options of MDS_WRITEVEC_LOC S/R.
141     - add vert. coordinate & horiz. indices to output files.
142     - change vertical position in initial condition, from index to depth [m].
143     - store horizontal (decimal) indices i,j in common block (instead of coord. x,y)
144       (easier to get to a curvilinear grid) ; delX,delY no longer used.
145    o pkg/ggl90: a few modifications:
146     - fix bottom boundary condition, and interpolation of KappaE
147       near top and bottom
148     - use same set of viscosity/diffusivity for TKE/momnetum/tracer
149     - add smoothing option as in Blanke and Delecluse (1993) (--> ALLOW_GGL90_SMOOTH)
150     - add a few options for mixing-length upper limit (--> mxlMaxFlag)  
151    o rename thetaMin,phiMin -> xgOrigin,ygOrigin
152      (maintain temporary backward compatibility, until next checkpoint)
153    
154    checkpoint61h
155    o pkg/diagnostics with "periodic averaging diagnostics":
156      fix S/R DIAGNOSTICS_COUNT ; hack diagnostics_out.F to get NetCDF output.
157    o pkg/my82: add missing "_d 0" ; update output of exp. vermix.my82
158    o pkg/obcs: fix loop ranges for balancing code
159    o pkg/flt:
160     - improve criteria for finding which tile owns a float.
161     - fix FLT_EXCH for case without MPI ; apply cyclic BC + fix also the MPI case.
162    o Add well-mixed CO2 box in aim_v23 (which includes changes in pkg
163      aim_compon_interf, ocn_compon_interf, gchem, and dic to get coupling
164      with ocean biogeo)
165    o pkg/flt:
166     - do some cleaning and fix the restart ;
167     - add output.txt in flt_example/results to get this pkg tested.
168    o genmake2: add an EXTENDED_SRC option and flag.
169       for now, cannot be turned on on command line (only through genmake_local)
170    o pkg/mdsio: read/write vector:
171     - singleCpuIO: fix RL/RS in MDSWRITEVECTOR by calling new S/R MDS_BUFFERtoRL/RS
172     - singleCpuIO=F: fix arrType & filePrec & _BYTESWAPIO in both MDSREADVECTOR
173       & MDSWRITEVECTOR by calling new S/R MDS_RD/WR_VEC_RL/RS.
174     - affects gradient of test-exp "bottom_ctrl_5x5" (not due to _BYTESWAPIO)
175      (drop to 4 digits matching for grad). But this test does not look very
176      reliable (was already failling on eddy, fc5, at 6.digits). Update output.
177    
178    checkpoint61g
179    o pkg/flt:
180      - move FLT_CPPOPTIONS.h to FLT_OPTIONS.h (standard name)
181       + make OPTIONS file more standard.
182      - rename S/R MDSREADVECTOR_FLT to FLT_MDSREADVECTOR (to mach src file name)
183      - fix _BYTESWAPIO CPP-Flag
184      - standard reading of file-parameter "data.flt"
185      - fix argument list of S/R FLT_RESTART
186      still need to fix _BYTESWAPIO in pkg/mdsio/mdsio_writevector.F
187    o pkg/obcs: fix a CPP-flag, bug reported by Jeff Blundell
188    o gather_2d.F/scatter_2d.F: suppress vectorisation on NEC SX in respond to
189      a still unfixed compiler/optimization bug
190    
191    checkpoint61f
192    o pkg/seaice, LSR solver: fix bug in GLOBAL_MAX calls ;
193      update results of global_ocean.cs32x15.icedyn test.
194    o move getcon.F from model/src to pkg/fizhi.
195    o pkg/exf: add parameter for extrapolation of temp up to the surface
196       and option to prevent negative evap (in bulk_largeyeager04 only).
197    o Prather Advection scheme: fix tracer conservation for divergent flow
198      (e.g., when using NonLin Free-Surface).
199    o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead
200    o gmredi (Visbeck-variable-K):
201     - add more parameters to Visbeck-variable-K.
202     - use a 5 points average for dSigmaR in Visbeck-K calculation
203       (more "homogenous": same stencil and same weights as in dSigmaH)
204     - update output of ideal_2D_oce experiment.
205    o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4
206      (#undef REAL4_IS_SLOW)
207     - pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4
208       coordinate variable
209     - pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables
210       (surface forcing fields), removes some of the functionality
211     - model/src/write_grid.F: write _RS variables as RS-netcdf variables
212     - model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but
213       probably not all: copy _RS surface flux fields to RL field before
214       calling DIAGNOSTICS_FILL
215     - model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into
216       real*4 (CALL EXCH_*_RS) versions.
217     - tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1
218       (generate new output).
219    
220    checkpoint61e
221    o gmredi (Visbeck-variable-K):
222      - fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h
223      - change computation of Visbeck-K where Slope > Smax :        
224        now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct)
225        previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output.
226    o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic
227      to be the same as with Z-coord. (i.e., m/s & no-units respectively).
228    o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc)
229    o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz
230      does not become too large (to avoid precision problems in implicit-diffusion
231      solver); update ideal_2D_oce output.
232    o pkg ggl90:
233      - in ggl90_cal.F: compute only one set of visc/diff, used to
234        step forward TKE/T/S/momentum
235      - default value of GGL90viscMax/GGL90diffMax larger and equal (to
236        have Prandlt =1)
237    o gmredi (fm07):
238      - add lower limit on Transition layer thickness + lower limit on 1/lambda
239      - allow to set few more params from data.gmredi
240    o pkg ggl90:
241          - add missing sqrt(2) factor in computation of mixing length
242            scale in ggl90_calc.F
243            (see Eq. (2.35) in Blanke and Delecluse, JPO, 1993)
244    
245    checkpoint61d
246    o adjoint modifs
247      - adapt to new field rhoInSitu
248      - allow to revert from StoreDynVars2D, StoreDynVars3D
249        to individual fields
250        (switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D)
251    o store 3-D (in-situ) density in commom block (DYNVARS.h)
252     - save 1 rho computation.
253     - no longer modify T & S inland when using down_slope pkg.
254    o gad_som : allow to switch to SOM advection for T & S without corresponding
255      pickup files (using new S/R: MDS_CHECK4FILE).
256    o keep removing _BEGIN/_END_MASTER between MDSIO S/R call
257      (for useSingleCpuIO to work in multi-threaded)
258    o pkg/shelfice:
259     - disentangle parameters: retire shelfIceFile in data/PARM05 and substitute
260       with SHELFICEtopoFile in data.shelfice
261     - move code for reading ice shelf topography and modifying hFacC into separate
262       subroutines of the shelfice package
263     - separate initialisation of "fixed" and "variable" variables
264     - kTopC is not (yet) replaced by kSurfC, although this is possible
265    o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s
266    o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors)
267      and rename:
268      ini_phiref.F          --> set_ref_state.F  (+ set anelastic factors)
269      ini_reference_state.F --> load_ref_files.F (- set anelastic factors)
270    o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst)
271    
272    checkpoint61c
273    o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid"
274      to add mass source/sink of fluid in the interior (3-D generalisation
275      of oceanic real-fresh water flux).
276    o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max)
277    o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before)
278    o new pkg: down_slope
279      density-driven downsloping flow parameterisation (Tellus, 1999, 412-430).
280      - presently, modify T & S inland (dwnslp_calc_rho.F).
281        can be avoided if rho was stored in common bloc and used in calc_phi_hyd.
282      - implementation for ocean in P-coords not tested.
283      - add secondary test to global_ocean.90x40x15 (input.dwnslp) to check this pkg.
284    o move kSurfC,kSurfW & kSurfS from SURFACE.h to GRID.h (next to kLowC)
285      (to facilitate conversion of oceanic pkg to p-coordinate).
286    o change FIND_RHO to FIND_RHO_2D :
287      pass arguments tFld & sFld as local (tile) 2D-arrays ; +fix EOS_CHECK.
288    o new pkg: cheapaml
289    
290    checkpoint61b
291    o exch2:
292      change index bounds in rx2_cube exchanges (new S/R: EXCH2_GET_UV_BOUNDS)
293      - no longer depend on the order sequence (N,S,E,W).
294      - 3rd exchange no longer needed (tested with 24 tiles).
295      - same modif to hand-written adjoint S/R (global_ocean.cs32x15: zero diff)
296      - exch_UV_A-grid readily available (but not yet tested).
297      comment out 3rd exch call and remove copy of V to U at SE & NE face-corners
298      (both are no longer needed) in exch_uv: no effect in forward run; but
299       get truncation error differences with adjoint exch.
300    o exch2:
301     - change index-bounds storage (moved from target to local tile,
302       more intuitive this way) ; rename/remove some variables.
303     - change utils/exch2/matlab-topology-generator & code_mods accordingly.
304    
305    checkpoint61a
306    o exch2/matlab-topology-generator:
307      fix bug in index bounds for N-S internal exchange (hard to tell if this
308      had any effect on the solution).
309    o pkg/mnc: small fix in mnc_handle_err: make sure that length of msgbuf
310      is exceeded
311    o testreport: modify syntax of awk, so that it works also with
312      awk, and not only with nawk and gawk
313    
314    checkpoint61
315    o autodiff
316      Change default for TAF usage by removing argument '-nonew_arg'
317      This changes TAF subroutine argument list (ordering of active var.)
318      Omission of this flag leads to incompatibility w.r.t. TAMC
319      To restore TAMC-compatibility, need following modifs:
320      * use adoptfile tools/adjoint_options/adjoint_tamc_compatibility
321      * use CPP option #define AUTODIFF_TAMC_COMPATIBILITY
322      Tested TAF version is 1.9.22
323      N.B.: exch2 hand-written adjoint code currently not TAMC compatible
324    
325    checkpoint60
326    --->>> This is the last checkpoint for which generating the adjoint
327    --->>> is done via the TAMC-compatibility TAF-flag "-nonewarg"
328    --->>> by default.
329    --->>> Future checkpoints will ommit this flag by default.
330    o pkg/generic_advdiff, os7mp: simplify and avoid division by zero.
331    o pkg/grdchk: Add gradient check to etan0 perturbations.
332    o pkg/exf: read ice area from file (#ifdef ALLOW_ICE_AREAMASK).
333    o pkg/autodiff: more flexibility in zeroadj.
334      model/src: modifying do_oceanic_phys.F accordingly.
335    o pkg/ctrl: Bounds for (kapgm,kapredi,eddypsi) parameter estimation.
336    o model/src and pkg/gmredi: GMREDI_WITH_STABLE_ADJOINT CPP option
337      special setup of gmredi for which the adjoint is stable
338      enough for parameter optimization.
339    o bridging the gap between eddy stress and GM.
340      -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
341          along with a change in CPP option (now ALLOW_EDDYPSI).
342      -> when using GM w/ GM_AdvForm:
343          The total eddy streamfunction (Psi = eddyPsi + K x Slope)
344          is applied either in the tracer Eq. or in momentum Eq.
345          depending on data.gmredi (intro. GM_InMomAsStress).
346      -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
347      The key modifications are in model/src/taueddy_external_forcing.F
348      pkg/gmredi/gmredi_calc_*F pkg/gmredi/gmredi_*transport.F
349    
350    checkpoint59r
351    o new S/R (pkg/mdsio/mdsio_facef_read.F) reading of sNx+1 x sNy+1 array
352      from per-face file (take S/R READSYMTILE_RS out of ini_curvilinear_grid.F);
353      fix option to read coriolis(@ cell-corner) from files with CS-grid.
354    o pkg/mnc: add some attributes to standard 1D-coordinate variables
355    o pkg/diagnostics: enforce missing_value attribute for scalar variables at
356      mass points, when using mnc for output
357      - add runtime parameter (missing_value, missing_value_int) to override
358        default (which is the value of getcon('UNDEF'))
359    o pkg/mnc: prepare mnc for the actual use of missing values with the
360      diagnostics package: small fix in mnc_cw_readwrite.template and more
361      initialisation of never used fields
362      - replace mnc_common.h and mnc_id_header.h with corresponding upper case
363      versions
364    o pkg/thsice/thsice_ini_vars.F added default initial values so that
365      thermodynamics sea ice solver does not blow up when some initial fields
366      are missing.
367    o move from external_forcing_surf.F to ini_forcing.F
368      the p-coord. hack consisting in using pLoad to set phi0surf ;
369      update output of tutorial_global_oce_in_p (affected @ truncation level).
370    o Freshen up a bit hs94.1x64x5, notably:
371      remove rotationPeriod and tRef=5*0. (adjoint only), and add
372      exactConserv=.TRUE.
373    o pkg/generic_advdiff:
374      change option GAD_ALLOW_SOM_ADVECT to GAD_ALLOW_TS_SOM_ADV which only
375      applies to files where Temperature & Salinity 2nd Order moments are used.
376    o pkg/ptracers: add second-order moment advection schemes (80 and 81);
377      this uses a dynamically allocated internal state data structure
378      (#define PTRACERS_ALLOW_DYN_STATE in PTRACERS_OPTIONS.h)
379      and requires a fortran 90 compiler
380    
381    checkpoint59q
382    o pkg/mom_vecinv: Add energy & enstrophy conserving scheme (selectVortScheme=3)
383       (from Sadourny, described by Burridge & Haseler, ECMWF Rep.4, 1977)
384    o Refresh tutorial_global_oce_biogeo, notably:
385      - change bathymetry (put back seamounts in ACC, use hFacs)
386      - change EOS (POLY3 --> JMD95Z)
387      - use Bryan-Lewis vertical diffusivity
388      - use multidimensional advection
389      - remove old virtual virtual in dic pkg, now done through ptracer pkg
390      - change a couple of parameters in dic pkg
391    o pkg/ctrl: change formula in adctrl_bound.F and add a parameter to ctrl_map_ini_gen.F
392    o pkg/obcs: change default to OBCSfixTopo = .true.,
393      - set OBCSfixTopo=.false. in exp4/input/data.obcs to reproduce old result
394      - replace "debugMode" with "debugLevel .GE. debLevB"
395    o implementation of TAF directives for gchem,cfc,dic
396    o remove "exp5" (replaced by tutorial_deep_convection).
397    o pkg/obcs: add code to fix topography gradients normal to open boundaries;
398      this requires computing the index fields OB_Jn/Js/Ie/Iw in obcs_readparms;
399      the code can be turned on by setting OBCSfixTopo = .true. in data.obcs
400      --> changes results in exp4, seaice_obcs
401    o tutorial_deep_convection :
402      update the set-up and increase resolution and domain size ; start
403      from pseudo initial conditions = output at t=120mn in order to see
404      something happening when running testreport.
405    o pkg/seaice: add os7mp as an advection scheme
406                  add check for advection schemes
407                  add a flag for restoring T and S underneath sea ice
408    o pkg/my82: add netcdf-support and diagnostics
409    o thsice pkg:
410      - Now hsMax limits snow height by turning it into ice following
411        flooding scheme (and now conserving energy)
412      - Slight rewriting of the formula in thsice_calc_thick.F
413      - Parameter rhowi eliminated to be replaced by floodFac = (rhosw-rhoi)/rhos
414      --> changes results of global_ocean.cs32x15.icedyn and global_ocean.cs32x15.thsice
415    
416    checkpoint59p
417    o gchem / dic / cfc :
418      - add useDIC, useCFC , read from "data.gchem" (& hold in GCHEM.h);
419      - add new parameter files: "data.dic" & "data.cfc" ;
420      - various re-arrangement in initialisation & header file ;
421      - fix tutorial_global_oce_biogeo for multi-threaded test.
422    o pkg/dic: test for "pickup_dic" file when restarting ;
423      if no pickup-file, can restart with a re-initialised pH (same as it did
424      before) providing pickupStrictlyMatch is set to False.
425    o change argument list of S/R PTRACERS_WRITE_PICKUP & MYPACKAGE_WRITE_PICKUP
426      + fix call to S/R GGL90_WRITE_PICKUP & DIC_WRITE_PICKUP
427    o add a "warning" (to Error msg file) when an Active Tracer is not using AB-2
428      and staggerTimeStep is off (needed for stability of Internal-wave dynamics).
429    o move out of PARAMS.h & data the last pieces of old-ptracer code: tauTr1ClimRelax,
430     & lambdaTr1ClimRelax ; put those 2 params in PTRACERS_PARAMS.h & data.ptracers
431       (note: not clear to me what lambdaTr1ClimRelax is still used for ...)
432    o pkg/mom_vecinv: - new parameter "selectVortScheme" to select which
433       scheme to use for vorticty-term ;
434     - compute upwindVorticity=T case within mom_vi_u/v_coriolis_c4.F
435       (with default selectVortScheme, return to original discretisation)
436     - remove weird combination (e.g.: upwindVorticity & highOrderVorticity)
437    o pkg/seaice: add a line to the summary to indicate grid type (B/C)
438    o in mom_calc_visc, fix average value of viscAh_W & viscA4_W next to the
439      bottom ; only used with variable horizontal viscosity and non-hydrostatic.
440      also fix diagnostics VISCAHW & VISCA4W.
441    
442    checkpoint59o
443    o dome/code/obcs_calc.F: avoid division by zero (detected using gfortran).
444    o change the loop ordering in most gad_*_adv_x.F to improve vectorization:
445      move a few statemens out the main loop into separate loops
446    o pkg/shelfice:
447      - sort out freshwater flux; convert freshwater fluxes to mass fluxes
448        (kg/m^2/s), does not break tests, because in verification/isomip,
449        rhoConstFresh=rhoConst (by accident)
450      - rearrange computation of tLoc, sLoc, pLoc to make code more efficient
451      - move S/R find_rho_scalar, pkg/ecco/sw_ptmp.F, pkg/ecco/sw_adtg.F into
452        new file model/src/seawater.F, so that they are available for all pkgs.
453      - convert potential temperature into in-situ temperature. This changes the
454        isomip tests => update tests
455    o add a flag writePickupAtEnd (default=true) to be able to suppress
456      writing a pickup at the last timestep
457    o tools/mpack-1.6 :
458      - disable automake (not working) and autoconf (not needed).
459      - update to version 1.6.4 which fix MD5 code on some 64 bits platforms
460        also cleaner with much less compilation warnings.
461    o pkg/profiles:
462      rename profiles_interp_mean_genericgrid as profiles_interp_mean_gg
463      (for "less than 32 characters name" compiler requirement)
464    o pkg/obcs and pkg/exf: added capability to specify seaice open boundary
465      conditions that have a different sampling frequency than S/T/U/V obcs
466    o pkg/diagnostics (stats-diags):
467      - fix global Min/Max in case 1 processor get only empty tiles
468    o genmake2: replace (4 times)
469         make genmake_tc_1.o >> genmake_warnings 2>&1
470      with
471         COMM="$CC $CFLAGS -c genmake_tc_1.c"
472         echo $COMM >> genmake_warnings
473         $COMM >> genmake_warnings 2>&1
474      to make genmake2 always see the value of CC as specified in the optfile.
475    o generic_advdiff: - prather advection scheme (SOM) coded for CS-grid.
476      - add diagnostics for 1srt & 2nd Order moments and sub-grid variance.
477      - modify verification advect_cs test to test SOM-advection on CS-grid.
478    o pkg/ctrl:
479      - Rewrite of ctrl_map_ini_ecco.F,
480        introducing a generic routine (ctrl_map_ini_gen.F).
481      - Modification of ctrl_bound/adctrl_bound handling control vector bounds.
482    
483    checkpoint59n
484    o pkg/diagnostics: for large number of diagnostics, store diagnostic mate
485      number in dedicate array "hdiag":
486      - new version of S/R DIAGNOSTICS_ADD2LIST : DIAGNOSTICS_ADDTOLIST
487        with 1 more argument (mate number); modify old version DIAGNOSTICS_ADD2LIST.
488      - many small changes (integer format) for large number of diagnostics
489      - start to use DIAGNOSTICS_ADDTOLIST (necessary for diagnostics with
490        a counter mate) in pkg diagnostics, ptracers, thsice & aim_v23.
491    o add parameter rotateGrid and Euler angles EulerPhi/Theta/Psi. For
492      usingSphericalGrid, this allows to define the rotated grid coordinates
493      via phiMin/thetaMin/dxSpacing/dySpacing, etc., but then re-compute the
494      geographical coordinates according to the inverse of the rotation defined
495      by the Euler angles, so that Coriolis parameter and online-interpolation by
496      exf works with the geographical coordinates on XC/YC/XG/YG.
497      Naturally, this feature does not work with all packages, so some
498      combinations are prohibited in config_summary (flt, flt_zonal, ecco,
499      profiles), because there the coordinates are assumed to be regular
500      spherical grid coordinates.
501    o pkg/gmredi,ctrl,ecco,autodiff,grdchk and model/src,inc:
502      - introduce isopycnal diffusion coefficient control.
503    o tools/adjoint_options:
504      - additional control vector components.
505    o pkg/mnc: have mnc create marginally meaning full coordinate variables
506      (that is the grid indices) if usingCurvilinearGrid and NOT EXCH2
507    o pkg/mypackage:
508      - add example of read/write pickup for state-var ;
509      - add entry points to the main code for state-vars diags & write-pickup.
510    o pkg/exf: rewrite of exf_getffieldrec.F to properly deal with year
511      transitions for useExfYearlyFields
512      - add new subroutine that determines the file to read from for
513        use*YearlyFields = .TRUE. and .FALSE.
514      - add a verification experiment to global_with_exf that tests
515        useExfYearlyFields with USE_EXF_INTERPOLATION defined
516    o pkg/obcs/exf: add useOBCSYearlyFields (=.FALSE.) to obcs with exf in
517      analogy to useExfYearlyFields; rearrange obcs_prescribe_read: two new
518      subroutines (which could be generated from a template, because they are
519      almost identical), for now they are included in obcs_prescribe_read.F for
520      simplicity
521    o pkg/exf:
522      - add a little more diagnostic to exf_interp_read (in analogy to
523        mds_read_field, can be turned off with debugLevel < debugLevA=1)
524      - improve vectorizability of exf_interp for TARGET_NEC_SX, makes code
525        ugly but fast by unrolling short inner loops, inserting a unroll=8
526        directive in routine lagran, and splitting a loop and making do while the
527        outermost loop (the latter requires the intoduction of index arrays)
528    o pkg/obcs: replace obcs_apply_area/heff/hsalt/hsnow with obcs_apply_seaice
529    o pkg/seaice: moved DIFFERENT_MULTIPLE from seaice_model to seaice_dynsolver
530      http://forge.csail.mit.edu/pipermail/mitgcm-devel/2008-January/003173.html
531    o verification/seaice_obcs: updated for restart test and latest options
532    o pkg/seaice: add a new flag SEAICEuseTEM to use a slightly different
533      ice rheology (so-called truncated ellipse, that gets rid of tensile stress);
534      for now this is only available for the C-grid code and also within
535      #ifdef SEAICE_ALLOW_TEM, because this option may slow down the EVP code
536    
537    checkpoint59m
538    o pkg/seaice: use different time constant for melting (SEAICE_gamma_t)
539      and freezing (SEAICE_gamma_t_frz) ice due to mixed layer temperature
540    o gad_som : fix flux output (& diagnostics) to have same units as other  
541      advection scheme fluxes (was previously multiplied by deltaT).  
542    o added verification/seaice_obcs both to test seaice open boundaries
543      and to provide an example matlab scrpt for generating them
544    o added verification/lab_sea/input.salt_plume for testing pkg/salt_plume
545    o pkg/salt_plume: clean up salt_plume_frac.F to
546      remove redundancy in PlumeMethod 1 and 4
547    o pkg/kpp: added saltplume diagnostics
548    o pkg/obcs and pkg/seaice:
549      - do not set uice and vice to zero when OB*icefile are unspecified
550      - OBCS_SEAICE_AVOID_CONVERGENCE is undefined by default
551      - moved seaice tracer obcs after call to seaice_growth
552    o pkg/salt_plume: added various options for salt plume depth
553      criterion and for vertical distribution of the salt
554    
555    checkpoint59l
556    o pkg/ptracers: new version of ptracers pickup:
557      read meta file and write only fields which are needed to restart.
558      ( same logic as main pickup file ; also using pickupStrictlyMatch )
559    o pkg/seaice:
560      - add timescale for melting due to warm mixed layer as a means of
561        setting SEAICE_availHeatFrac more conveniently
562      - add a CPP-flag/runtime parameter check for flooding algorithm
563      - reformulated availHeat in seaice_growth.F to be independent of AREA
564    o change units attribute of EmPmR netcdf variables to kg/m^2/s to reflect recent
565      unit changes
566    o pkg/obcs: added OBCS_SEAICE_AVOID_CONVERGENCE constraint
567    o cg2d.F: add 3 compiler directives that speed up this routine by 30% on a NEC
568      SX vector computer.
569    o pkg/seaice:
570      - removed SEAICE_FFIELDS.h and seaice_get_forcing.F
571        seaice forcing fields can now be read only through pkg/exf
572      - removed some unused halos
573    o no longer write pickup from THE_MODEL_MAIN but always from FORWARD_STEP
574    o pkg/exf: added useRelativeWind EXF_PARAM.h option for subtracting U/VVEL
575      or U/VICE from U/VWIND before computing U/VSTRESS
576    
577    checkpoint59k
578    o pkg/seaice: ICE2WATR=SEAICE_rhoIce/rhoConst for consistency between
579      dynamics and thermodynamics. Set ICE2WATR=0.92 to reproduce older results.
580    o fix un-initialised variable problem (in mom_vecinv & shap_filt):
581      all experiments pass when compile with un-initialised var. checking option.
582    o added pkg/salt_plume
583    o script to test restart (for now, in MITgcm_contrib/jmc_script)
584    o pkg/seaice: new read/write pickup version.
585      read meta file and write only fields which are needed to restart.
586      ( same logic as main pickup file ; also using pickupStrictlyMatch )
587    o pkg/seaice: fix bug in seaice_ocean_stress (call of seaice_calc_strainrates)
588    o lab_sea.hb87: modify the domain & update output.hb87.txt :
589      lat-long grid & no-slip BC in seaice-dynamics produce different sigma12
590      at j=1 & j=Ny+1 : this case is not treated correctly in the restart
591      process. Fixed here by closing the domain at the Northern boundary.
592    o pkg/rw: cleaning-up: call directly new MDSIO S/R MDS_READ/WRITE_FIELD.
593    o pkg/mdsio: add new arguments to MDS_READ/WRITE_FIELD for reading/writing
594      a set of consecutive levels in/from a 3-D array.
595    o pkg/ptracers:
596      use a 2 characters string ioLabel to identify tracer (if more than 99 tracers).
597      to-do: fix pkg/diagnostics when large number of diagnostics are defined.
598    
599    checkpoint59j
600    o in pkgs: dic, obcs, offline, rbcs:
601      standard way to compute coeff. for time interpolation between 2 time reccords
602      which retains full precision (& make results less dependent on compiler).
603      update output of exp: tutorial_cfc_offline & tutorial_global_oce_biogeo.
604    o pkg/cfc: if compiled with exf and seaice, cfc now can use fields from those
605      packages instead of reading ice cover and wind speed separately
606    o split PTRACERS.h in 2 header files: PTRACERS_FIELDS.h & PTRACERS_PARAMS.h
607     (keep a temporary version of PTRACERS.h in verification/OpenAD/code_ad_openad
608      to allow to compile customized code before the update)
609    o cleaning-up:
610      - fix CPP instruction syntax in pkg/obcs
611      - replace (some) call to MDSIO S/R with call to RW interface S/R ; and
612        add #ifdef ALLOW_MDSIO elsewhere (allows to compile without pkg/mdsio)
613      - fix some threads issue in IO parts.
614    o pkg/dic:
615      - add tons of "_d 0" (--> much better testreports !)
616       and then update outputs of tutorial_global_oce_biogeo
617  o pkg/mom_fluxform:  o pkg/mom_fluxform:
