4      ==============================      ==============================
5    o re-arrange diagnostics pkg initialisation:
6     - allow each package to extend the available diagnostics list
7     - add some checking and fix small problems (multi-threaded, ...)
8     - new S/R diagnostics_fill (replace fill_diagnostics):
9       look through the short list of active diag. (instead of the long list)
10       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
11    
12    checkpoint57a_post
13    o this set of changes restores TAMC compatibility
14      tested for global_ocean.90x40x15 adjoint on trough
15      (what a pain)
16    
17    checkpoint57a_pre
18    o some modifs in tools/build_options for sunos
19    o call ctrl_pack for ctrl at end for optimcycle=0
20    
21    checkpoint57
22    o add horizontal bi-harmonic viscosity for vertical velocity
23      - new parameter viscA4W (defaults to viscA4)
24      - affects only non-hydrostatic code
25      - to be done: no-slip lateral boundary conditions
26    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
27    o implement Implicit Vertical advection for pTracers
28    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
29      (implemented also for implicit vertical diffusion & advection)
30    o OBCS: extend application of tracer open boundary conditions
31      to a strip beyond the boundary of width Olx/Oly
32    o add call monitor to TAF set of required calls (flow directives)
33      and include in natl_box_adjoint
34    o untangle a few ifdefs related to cost, ctrl, autodiff
35      untangel a few ALLOW_ECCO_OPTIMIZATION
36    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
37      (theta2, salt2 in ecco_cost_weights)
38    
39    checkpoint56c_post
40    o OBCS as control variables
41      - update ctrl_ad_diff.list, obcs_ad_diff.list
42      - remove balance of obcs controls from default
43      - fix index bug nobcs in ctrl_init
44      - fix dummy fields filen in ctrl_pack
45      - add dummy weights for obcs
46    o lsopt: comment out fort.94 output
47    o optim:
48      - remove unnecessary header files
49      - adjusted namelists
50      - add xerbla.F to Makefile
51    o exf:
52      - multiple modifications of exf_check_range
53      - unit change in exf_init_runoff from [m/year] to [m/s]
54    o mdsio:
55      - i/o-vector change debugLevel from debLevA to debLevB
56    
57    checkpoint56b_post
58    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
59      is called from DO_THE_MODEL_IO
60      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
61      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
62      - clean up PTRACERS_WRITE_TIMEAVE a little
63    o add another verification experiment that tests both the cfc-pkg and
64      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
65      reactive tendencies treated inline with regular timestepping
66    o testreport previously did a lousy job of comparing small numbers, so
67      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
68      implemented in the little c-progam tmp_cmpnum.c which is embedded in
69      testreport.
70    o ptracers_monitor: bug fix for MPI
71    
72    checkpoint56a_post
73    o GCHEM: finish reorganizating the package
74      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
75        (introduces another 3D-array for each passive tracer, but only if
76        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
77        gchemTendency is not needed because the timestep is done separately)
78      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
79      - GCHEM is now---more or less cleanly---separate from PTRACERS
80      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
81        so clear to me how that should be done in a general way.
82    o CFC: improve formatting of output in CFC_ATMOS
83    o PTRACERS:
84      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
85        that ALL experiments with ptracers enable can be checked. This makes
86        GCHEM_MONITOR obsolete.
87      - include a runtime parameter PTRACERS_monitorFreq that defaults to
88        monitorFreq
89      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
90    o add PTRACERS (PTR0[1-5]) to testreport output
91    o exf_check_range:
92      * default changed to .TRUE.
93      * will check values for niter0 if debLevA, every timestep if debLevB
94      * STOP in exf_check_range if 'out of range'
95      * range chosen generous to allow for potential extema
96      TBD: a version with stricter range
97           permitted range would be runtime parameters
98    o GMredi:
99      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
100      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
101      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
102    o GCHEM:
103      - move call to GCHEM_FORCING_SEP, so that it is now called before
104        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
105      - introduced a useGCHEM runtime flag and applied it everywhere.
106      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
107        this flag is now only visible within GCHEM-pkg routines.
108      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
109        be replaced by a 3D array that is computed before thermodynamics; for
110        this, the tracer ID iTracer had to be included into the parameter list
111        of ptracers_forcing
112      - set up forward_step to call gchem_forcing, that will replace
113        gchem_forcing_int in ptracers_forcing
114      - cleaning up
115    o small cleaning of exch2: remove files that are also in eesupp/src
116    
117    checkpoint56
118    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
119    o mnc: cleanup "full" files--fixes out-of-memory problem
120    o ECCO-GODAE
121      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
122      * fully merged and updated from SIO code
123        windstress sign change affects
124        - exf_inscal_[u/v]stress
125        - sign of xx_tau[u/v] adjustments
126        - signs in cost_scat
127      * ctrl_get_gen: avoid update of tau[u/v] for first few days
128      * natl_box_adjoint updated and compressed
129      * 2-level checkpoint switch added
130        (tested in EXP. 1 of natl_box_adjoint)
131      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
132    o SVD
133      * first complete, non-hacked version for SVD calculations
134      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
135        performed via direct access files admtlm_vector.it????
136        (via ctrl_[un]pack)
137      * optimcycle is used for ARPACK iteration counter
138        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
139      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
140        and add linear transforms where necessary
141      * controls are initial/final SST, SSS (can be extended; need to check
142        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
143    o mdsio: filename info to both stderr, stdout
144    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
145      from sign change
146    
147    checkpoint55j_post
148    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
149      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
150    o add consistent build directories and .cvsignore files to verification
151    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
152    o make all subroutines 30 or less characters in length for certain older
153      compilers to work (a thorough search only turns up two routines in
154      pkg/ptracers)
155    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
156      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
157    
158    checkpoint55i_post
159    o change arrays for total vertical diffusivity (2.D if explicit,
160      3.D if implicit) ; each ptracer uses its own background value.
161    o added mnc/NetCDF output capability to ocn_compon_interf
162      - added bits to verification/cpl_aim+ocn so that it can run on
163        ITRDA and other clusters without the mpirun "-wd" option
164    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
165      configuration
166    o give MNC the ability to create additional files rather than
167      exceeding a specified file size limit "MNC_MAX_FILESIZE"
168      - the default is just less than 2GB which is a practical limit
169        on many systems
170    o Compute the non-local term using either KPP vertical diffusivity (=default)
171       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
172    
173    checkpoint55h_post
174    o add verification test "vermix"
175    o remove all the *_ioinc flags and replace with the single global
176      outputTypesInclusive flag
177    o allow to set a vertical profile of vertical diffusivity for T & S
178    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
179    o useMNC moved from data.mnc to data.pkg
180    
181    checkpoint55g_post
182    o Renaming carbon AD experiments to comply with testreport conventions
183    o Updating adjoint of Held-Suarez hs94.1x64x5
184    o Fixing directives for non-ECCO forward_step, after ECCO directives
185      have been fixed to avoid recomp. of do_oceanic_phys
186      Works well for global_ocean.90x40x15,
187      but recomp. issue remains for carbon
188    o Updating adjoint output for natl_box_adjoint after
189      pkg/ecco has been modified (see taga c55d_post)
190    
191    checkpoint55f_post
192    o rename to timeave_init_fixed
193    
194    checkpoint55e_post
195    o some delicate re-shuffle of store directives to avoid one
196      extra call of do_oceanic_physics
197      affects ecco_the_main_loop.F, do_oceanic_physics.F
198      checkpoint_lev1_directives.h
199    o NB: this may break global_ocean adjoint temporarily,
200      but it is clear how to fix it. Will do later, need this now.
201    
202    checkpoint55d_post
203    o ECCO specific cost function terms (up-to-date with 1x1 runs)
204    o ecco_cost_weights is modified to 1x1 runs
205    o modifs to allow observations to be read in as
206      single file or yearly files
207    o enable to read exf forcing fields as either
208      single file or yearly files (flag useExfYearlyFields)
209    checkpoint55d_pre
210    
211    o switch between 2-level and 3-level checkpointing
212    o add ability of MNC to write local and "partial" (eg. 2D slices where
213      the full 3D field is never actually stored) arrays to NetCDF files
214      with the correct (that is, the complete multi-dimensional) set of
215      array indicies
216      - used in mom_vecinv() to write the diagFreq output
217      - tested (demonstrated) in verification/aim.5l_cs
218    o further mnc-ification
219      - add verification/lab_sea to the list with mnc setups
220      - fix undefined mnc v-names in cd_code
221      - add kpp to mnc output (both snapshot and timeave)
222    o non-hydrostatic code
223      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
224        in calc_gw.F
225      - defaults to viscAh
226      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
227        friction or Leith) in non-hydrostatic mode, as long as there is
228        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
229    o pkg/cost
230      extend simple cost functions to treat time mean quantities
231      (T,U,V) via cost_accumulate_state from cost_tile
232    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
233        be 2 times larger than the minimum size the advection scheme requires.
234        now get a perfect conservation of salt in advect_cs test-exp (updated)
235    o GGL90 (Gaspar's TKE mixed layer)
236      - add horizontal diffusion of TKE, requires exchanges in
237        do_fields_blocking_exchanges, horizontal diffusivity is zero by
238        default. In OPA there is no horizontal diffusion of TKE but the
239        mixing coefficients are computed from a horizontal average of TKE of
240        6 points or so. I think that diffusion has a little more physical
241        justification.
242      - clean up ggl90_calc in the hope of reducing memory usage (this hope
243        was in vain)
244      - mask tke-variable in ggl90_init
245    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
246    o fix biharmonic diffusion on CS-grid.
247    o more obcs stuff
248      - added obcs_external_fields_load as an alternative to the EXF-pkg option
249        for reading boundary values. This routine is called from
250        obcs_prescribe_read
251      - updated obcs_check
252      - changed sponge layer relaxation parameter units for days to seconds
253      - turned off sponge layer by default
254      - changed argument list of OBCS_CALC to myTime+deltaTclock
255      - fixed about 35 bugs in obcs_external_fields_load
256    
257    checkpoint55c_post
258    o obcs stuff
259      - new runtime flags useOBCSprescribe, useOBCSbalance
260      - re-arranged obcs_calc
261      - moved exf_getobcs to obcs_prescibe_read
262        obcs_prescibe_read is called after ORLANSKI stuff
263        and independent of it (executable can contain all).
264      - updated obcs_check
265      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
266        These may be necessary only if tangential velocities are
267        prescribed at OB, not sure, needs testing.
268    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
269      which simplifies the calls and passes the ifc check-bounds test
270    
271    checkpoint55b_post
272    o add a 2D scalar, Z location, exchange_2 routine.
273    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
274      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
275      affects advect_cs results (for the wrong reason): update output.txt
276    o use a more standard discretization for biharmonic viscosity ;
277     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
278      affects results of dome set-up: update output.txt
279    o fix gad_advection.F (CubedSphere part), back to version 1.23
280    o fix bug in mom_vi_del2uv.F (CubedSphere part).
281    
282    checkpoint55a_post
283    o merged code to
284      * prescribe/read time-dependent open boundaries
285        (works in conjunction with exf, cal)
286      * sponge layer code for open boundaries
287      * each boundary N/S/E/W now has its own CPP option
288        (healthy for the adjoint)
289    
290    checkpoint55
291    o up-to-date adjoint of previous breaks
292      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
293      - global_ocean_ebm: adjoint still needs fix (TLM ok)
294      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
295      - carbon: * remove tr1-related adjoint verification
296                * add ptracer as control variable
297    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
298      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
299    
300    checkpoint54f_post
301    o in verification/carbin/ remove experiment related to
302      ALLOW_PASSIVE_TRACER (array tr1 etc)
303      code_ad/ input_ad/ results_ad
304    
305    o add two new packages
306      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
307        + subject to optimization (memory)
308      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
309        + subject to reordering (many GOTOs in the original code)
310        + so far opps is called for every (i,j) point, and then operates in
311          the vertical; one may want to reorder the scheme in order operate in
312          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
313          fields)
314    o overhaul of IO so that we now have flags for MDSIO and/or MNC
315      - all verification tests compile and run with linux_ia32_g77
316      - defaults are compatible with current input files--nothing
317        should change if you were not previously using MNC
318      - MNC output has been added in numerous places (eg. timeave)
319        but there are still a few writes not yet do-able with MNC
320        (this is in progress)
321      - flags now allow for either/or/both use of MDSIO and MNC and
322        documentation will soon follow
323      - numerous small formatting cleanups for ProTeX
324    o add version info (via BUILD_INFO.h) to MNC and stdout
325    
326    checkpoint54e_post
327    o add two new packages
328      - pp81 (Packanowski and Philander, 1981), Richardson number and
329        stratification dependent mixing
330      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
331      - these scheme operate in a similar manner as KPP (without ghat, of
332        course), however there is only one diffusivity that is used for both
333        temperature and salinity (and passive tracers)ç
334    o add offline package
335    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
336      provided by Stephanie Dutkiewicz
337    o genmake2: add ability to search for C compilers and cleanup test output
338      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
339    
340    checkpoint54d_post
341    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
342    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
343      leading to additional shift by 5 days each year of integration
344       (i.e. leading to considerable offset over the years)
345    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
346    o start with no AB and no initial filtering (staggerTimeStep):
347      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
348    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
349      (external loading & cpl import/export stay in forward_step.F)
350    o update coupling interface to work with new staggerTimeStep
351    o change MDSIO ptracers_pickup.
352    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
353    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
354    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
355    
356    checkpoint54c_post
357    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
358      this affects (truncation error) output.txt of test-exp:
359       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
360    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
361    o change Qnet to always be the net heat flux, (+upward).
362      affects (truncation error) output of natl_box exp.: updated
363    o define the max number of passive tracers in PTRACERS_SIZE.h
364    o start to test mnc routinely in exp0
365    o add sea-ice loading (sIceLoad) as a new forcing field.
366    
367    checkpoint54b_post
368    o add testreport "-j JOBS" option for parallel builds (tested and pretty
369       impressive on Altix and Opteron systems)
370    o diagnostics can now write NetCDF files through the mnc package
371    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
372    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
373    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
374      affects (truncation error) output of lab_sea & natl_box exp.: updated
375    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
376    
377    checkpoint54a_post
378    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
379    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
380    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
381    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
382      + internal_wave (shift in writing cg2d_ini_res)
383    checkpoint54a_pre
384    
385    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
386      - modified verification/lab_sea and natl_box_adjoint accordingly
387    
388    checkpoint54
389    checkpoint53g_post
390    o prepare splitting of thermodynamics: store convect.counter in common block
391    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
392      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
393    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
394    o new parameter "nShapS": allow to treat differently S from T (nShapT)
395    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
396    o restore adjointability
397    
398    checkpoint53f_post
399    o modifications that affect AIM experiment results (update output.txt):
400      - no advection of S at top interface Nr (pkg/generic_advdiff)
401      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
402    o AIM pkg:
403      - include stability function into surf.Flux derivative relative to Tsurf
404      - calculate clear-sky radiation & surface temp. change (for diagnostics)
405    
406    checkpoint53e_post
407    o merged cylindrical coord configuration
408    o added rotating_tank experiment
409    checkpoint53e_pre
410    
411    checkpoint53d_post
412    o faulks upgraded: re-generate output.txt that have changed:
413       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
414    o Added Bryan and Lewis, 1979, vertical diffusivity profile
415    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
416    o added Sadourny discretization of Coriolis
417      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
418      - re-enabled use of omega3 (useAbsVorticity)
419    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
420      vector-invariant equations
421      - note: does *NOT* yet use same variable visc. for no-slip BC's.
422    o recoded the lateral boundary conditions for non-hydrostatic w, this time
423      hopefully without new bugs
424      - still to do: biharmonic friction for non-hydrostatic w
425    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
426    o regenerated output for global_ocean_ebm (using -ieee)
427    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
428      of mom_common/
429      - simple re-arrangement of instructions within computing loop
430    checkpoint53d_pre
431    
432    checkpoint53c_post
433    o new version of coupler for AIM+thSIce and Ocean models
434     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
435     - land: change Evaporation of snow
436     - aim with thSIce: fix bug in snow-precip.
437    o changes to calc_gw.F
438     - bug fix for w^2 term near the bottom boundary
439     - (hopefully) improve the lateral slip boundary condtions for use with
440        partial/looped cells
441      - because the bug fix changes two verification experiments anyway (exp5
442        and plume on slope), change the lateral boundary condition from half slip
443        to the value of no_slip_sides
444    o ebm package wasnt quite up to the parallel task. Fixed that.
445    o Adjoint of EBM package + verification
446      * TLM OK
447      * ADM not sufficient accuracy yet (needs further testing)
448    
449    checkpoint53b_post
450    o Commiting new energy balance model to repository
451      * package is pkg/ebm
452      * verif. is verification/global_ocean_ebm
453      * references are in ebm_driver.F
454    C      * X. Wang, P. Stone and J. Marotzke, 1999:
455    C        Global thermohaline circulation. Part I:
456    C        Sensitivity to atmospheric moisture transport.

464    C        by atmospheric eddy transports.
465    C        J. Climate 7(12), 1870-1882
466    o Will need long integration testing.
467    checkpoint53b_pre
468    
469    o created pkg/mom_common in preparation for variable viscosity code
470    o renamed and split ini_mnc_io
471    o pkg/land: only liquid water can diffuse or run-off
472    o AIM using land: soil wetness availability account for snow
473    o added printMapIncludesZeros to EEPARMS namelist
474    
475    checkpoint53a_post
476    o restore TAMC compatiility for exf_constants.h
477      (no usage of _d in .h)
478    o Additional storing in KPP in an attempt to fix
479      TAMC problem with adjoint of KPP code.
480      (no success...)
481      Identical code works fine with TAF.
482    o Fixed verification/natl_box_adjoint experiments.
483      Initial conditions for Experiments 4 and 5 are now
484      set to "SEAICE_initialHEFF=0", which is more reasonable,
485      and hence gives results closer to that of Experiment 2.
486      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
487    
488    checkpoint53
489    o stable checkpoint with up to date adjoint
490      TLM tests only run for 1st grdchk at the moment. Its unclear if
491      this is a code problem or a problem with resetting code for g_
492      variables that is being autogenerated wrong.
493      Otherwise:
494       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
495       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
496         are both still in chaos following their security messes.
497    
498    checkpoint52n_post
499    o various build (mostly genmake2) changes including:
500      - ability to build/run more easily within Cygwin and MacOS X
501      - more complicated Makefiles with a stronger dependence on Gnu Make
502    o pkg/seaice modifications
503      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
504        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
505        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
506      - changed proxy for geostrophic velocity and updated
507        verification/lab_sea/results/* accordingly
508      - removed ADI dynamic solver from pkg/seaice
509      - replaced all occurrences of 1/CSTICE or 1/CSUICE
510        they caused a segmentation fault under certain circumstances
511      - removed unused field WATR
512    o bug fix in exf-package:
513      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
514         now reflect that.
515    o small fixes in the cal-package:
516      - set reference date to first of January for the 'model'-calendar
517      - failing of cal_CheckDate in cal_FullDate now actually results in a
518        warning
519    o small modifications in exf-package to increase flexibility:
520      - change climtempfreeze from a constant to a runtime parameter that
521        is specified in data.exf_clim (default = -1.9)
522      - introduce runtime parameter windstressmax (default = 2.0) that is
523        specified in data.exf
524    o fix in pkg/thsice:
525      - update Evap (Tsf changes) to be consistent with Latent heat flux
526      - maintain snow precipitation unchanged (even if Tsf >=0).
527     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
528    
529    checkpoint52m_post
530    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
531      this does not change any of the results, because myIter=0 in swfrac always
532      lead to jwtype=2 (the default anyway), but the call makes little sense
533      as a default
534    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
535    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
536      atmospheric model (AIM) to use it ; add a "slab ocean" component.
537    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
538    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
539    o extending useSingleCpuIO option to work with new exch2 I/O format
540      - old-style, missing-tile I/O is still accessible by defining CPP
541        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
542    o monitor package can write to NetCDF files and/or STDOUT
543    o fix re-definition bug in MNC_GRID_INIT_ALL()
544    o doc/api_reference added
545      - a framework for building an API Reference Manual using all
546        the "protex" comments embedded in the code
547      - see pkg/generic_advdiff, pkg/mnc for examples
548    o MNC:
549      - make myThid the last argument for all subroutines
550      - new default for the grid files: NO halos
551      - add useMNC and other run-time flags
552      - separate per-file-group handling of the unlimited dimension
553      - early initialization of MNC w/ flags read at the eeboot stage
554        and lookup tables set in initialize_fixed
555      - write all MNC output to a freshly-created directory
556    o thermodynamics sea-ice (thsice) is now tested with testreport.
557    o test exp. advect_cs: use the standard cs32 grid ; update output.
558    o Added functionality to grdchk:
559      pick global i,j,k position (or nearest wet) where to perform check.
560    
561    checkpoint52l_post
562    o new land formulation:
563      a) use ground enthalpy as prognostic variable to ensure exact
564         energy conservation.
565      b) account for water temperature and for latent heat of freezing
566         in all processes (rain, run-off, ground storage)
567      c) compute surface and ground temperature implicitly.
568    o aim_v23 modification for new land model:
569      a) Treat separately land / ocean / sea-ice surface fluxes
570         to allow implicit computation of land & sea-ice surface temp.
571      b) add snow precipitation.
572    checkpoint52l_pre
573    
574    o fix problem (when 1 tile is empty) in min/max monitor.
575    o fix bug in timeAve (u,vZetatave in common block)
576    o no restoring terms under ice for pkg/seaice
577    o moved SEAICE_DO_DIAGS to S/R do_the_model_io
578    o bug fix for pkg/seaice pickups
579    o change MNC call locations and add coordinate attributes
580    o mask vorticity at the corner ; affects global_ocean.cs output
581    o fix ini_curvilinear_grid ; test CS experiments with mpi
582    o aim.5l_cs: modify sea-ice fraction input file ; update output
583    o exf: Adding simple range check routine for exf fields after read
584    
585    checkpoint52k_post
586    o removed top-level directory "diags"
587      - we migrated these functions to pkg/timeave a long time ago
588    o fixed bug introduced in pkg/monitor
589    o accuracy ctrlprec = 32 insuffient for gradient checks using
590      averaged fields (I/O via cost_averages)
591      -> use ctrl.h in active_file*.F to control I/O precision.
592    o paramter list of CALL ADTHE_MAIN_LOOP
593    o added initial do_the_model_io to ecco
594    o set all ...Freq to zero after cost_final
595      taveFreq, dumpFreq, pChkptFreq
596    o MAIN and ECCO differentiability restored
597    
598    checkpoint52j_post
599    o fix nchklev in tamc.h for global_ocean...
600    o Bringing flow and store directives up-to-date
601    o Really weird thing!
602      call do_the_model_io from the_main_loop with parameters
603      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
604      TAF places a faulty re-call of initialise_varia
605      after cost_final call which should not be there!
606    checkpoint52j_pre
607    
608    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
609      error messages
610    o fix errorMessageUnit problem. remove old version of mdsio from eesup/src
611    o modified pkg/mdsio/mdsio_readfield.F -- commented out diskspace-eating
612      debug output
613    o modfied mdsio_writefield.F to handle non-global files under exch2
614    o update AIM Cubed-Sphere exp (aim.5l_cs):
615      use land, p*, and Franco.M forcing fields with fractional land-sea mask.
616    o update AIM Equatorial Channel exp:
617      use standard aim_v23 pkg and change the SST fields to be more realistic.
618    o globalFile now works with exch2
619    o merged mom_vi_calc_relvort3.F, mom_vi_del2uv.F and
620      mon_vort3.F to make exch2 friendly with >1 tile per cube face
621    o limit timeave output for hi-res integrations
622    
623    checkpoint52i_post
624    o removed CPP_EEOPTIONS.h from verification/*/code
625    o updated the tiling for global_ocean_pressure
626    checkpoint52i_pre
627    
628    o update aim.5l_LatLon using the standard aim_v23 pkg (instead of
629      the old pkg/aim).
630    
631    checkpoint52h_pre
632    o shortened offending lines in exch2_send_rx?.template
633    o modified W2_EXCH2_TOPOLOGY.h to reflect current topology generator
634    o genmake2: add build & execute test for NetCDF code
635    o modded aim.5l_cs and global_ocean.cs32x15 to use exch2, removed
636      old grid files, moved CPP_EEMACROS.h to pkg/exch2
637    o added useSingleCPUIO flag to monitor.F and mon_out.F
638    o added temporary hack for sea-ice dynamics on the cube:
639      metric terms are ignored and it is assumed that
640      there is no sea-ice on cube faces 1, 2, 4, and 5.
641    
642    checkpoint52f_post
643    o added exch2 cube routines to pkg/exch2
644    o modified hs94.cs-32x32x5 to use it
645    o added new grid files to hs94.cs-32x32x5
646    checkpoint52f_pre
647    
648    checkpoint52e_post
649    o first attempt to solve vertical advection (momemtum & T,S) Implicitly
650      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
651    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
652      to work with implicit vertical advection and AB ;
653    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
654    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
655     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
656    checkpoint52e_pre
657    
658    o fix bug in impldiff when Nr=1 or Nr=2.
659    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
660    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
661    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
662      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
663    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
664    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
665    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
666    
667    checkpoint52d_post
668    o re-tiled many expts to allow comparison in multi-processor mode
669      - updated output accordingly
670      - changed hs94.128x64x5 to use intial T from file rather than use the
671        random number generator
672    o add infrastructure in model routines for fizhi and gridalt packages
673    o change global_ocean.cs32x15 because of Pb with GM on CS-grid.
674    o changes to permit hi-res, cubed-sphere, configuration
675      - added useSingleCpuIO capability to mdsio_readfield.F and exf_interp.F
676      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
677      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
678        of surface winds for the cube
679      (A verification experiment, based on global_ocean.cs32x15, but with
680       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
681       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
682       complete with example surface forcing files and matlab scripts to look
683       at the output and compare it with that of global_ocean.cs32x15.)
684    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
685       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
686       to conform to the common rule.
687    o check-in the first version of the coupler + interfaces for multi-components
688       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
689       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
690       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
691       - ocean and atmos. share the same horizontal grid (no interpolation).
692       - exchanges between component and coupler is done in forward_step
693    o new verification experiment, cpl_aim+ocn:
694       coupled ocean - AIM atmosphere on cs32 grid.
695    
696    checkpoint52d_pre
697    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
698    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
699    
700    checkpoint52c_post
701    o Fixing OPTIONS files for use of exf:
702      - ALLOW_ECCO not needed
703      - ECCO_CPPOPTIONS.h should not be included from
704        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
705        as has been the case in the past
706      - All cal/exf related options are currently set in
707        single header file. Should remain so until we
708        agree on a consistent new policy.
709    o Removed all CPP options for cal package.
710      cal has no more CPP options.
711    o modified STOREs in GAD_ADVECTION
712    o corrected key comp. for passkey
713    
714    checkpoint52b_post
715    o new version: "thsice" of thermodynamic sea-ice pkg:
716     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
717     - modify fluxes but do not change theta directly;
718     - light cleaning of bulk_force pkg (still needed with thsice).
719     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
720       + output_thsice.txt to test thsice & bulk_force pkgs.
721    o put back grid & coriolis monitor output.
722    checkpoint52b_pre
723    
724    o call "do_the_model_io" at the beginning (=> dump initial state)
725    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
726    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
727      (need info on NUMBER_OF_PTRACERS)
728    o missing PTRACERS headers in some routines
729    o default tamc.h in pkg/autodiff supposed to crash
730      to ensure proper customization
731    
732    checkpoint52a_post
733    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
734      - moved surfaceTendencyTice from pkg/seaice to main code
735      - subroutine FREEZE_SURFACE now limits only surface temperature
736        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
737        => new output.txt for global_ocean.cs32x15 & global_with_exf
738      - keep the old version of FREEZE for backward compatibility;
739        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
740      - corresponding modifs for TAF directives
741    o added surface flux output variables to TIMEAVE_STATVARS
742    o time-averaged output for pkg/ptracers
743    o fix problem with ECCO-related divided adjoint
744      snapshot file was missing some ad-variables,
745      but no warning issued by TAF
746    
747    checkpoint52a_pre
748    o some bug fixes for #undef REAL4_IS_SLOW
749    
750    checkpoint52 = ecco_c52_e35
751    o after testing adjoints of checkpoint51u_post
752    
753    checkpoint51u_post
754    o this is the post-merge tag of the ecco-branch
755      (needs another clean checkout and re-testing)
756    o various natl_box_adjoint configs and results
757      but no input fields
758    o obcs adjoint not yet merged!
759    o adding ECCO global 1x1 and 2x2 degree configs
760    o updated/extended some store directives for seaice
761    o pkg/ecco now containes ecco-specific part of cost function
762    o top level routines the_main_loop, forward_step
763      supersede those in model/src/
764      previous input data.cost now in data.ecco
765      (new namelist ecco_cost_nml)
766    o in ctrl/ cleaned some cross-dependencies and updated CPP options
767    
768    checkpoint51t_post
769    o this is the pre-merge tag of the ecco-branch
770    
771    checkpoint51s_post
772    o cleanup: removed various obsolete #define-s
773    o pkg/grdchk
774      - renamed 'ph-grd 3' to 'grad-res'
775      - merged from ecco-branch
776        (remaining bug fixes for obcs gradient checks)
777      - additional high-precision output for testreport
778        (grep for 'precision_grdchk_result')
779    
780    checkpoint51r_post
781    o cleaned up or removed CPP_OPTIONS.h files
782    o updated results for some of the tests to reflect the new
783      optfiles (-ieee: -O0 instead of -O3)
784    
785    checkpoint51q_post
786    o cd_code:
787      - moved cd_scheme.F -> cd_code_scheme.F
788      - separate read_checkpoint from cd_code_ini_vars.F
789      - separated cd_code part from write_checkpoint
790      - updated AD_SOURCE, generated .flow

793    o ctrl package totally restructured
794      - pack/unpack now optional and decoupled from
795        xx_/adxx_ I/O
796      - ctrl_pack/unpack cleaned
797        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
798      - confined inclusion of AD_CONFIG.h to where necessary.
799    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
800    
801    checkpoint51p_post
802    o create initial cd_code package
803      - WARNING: the initialization of fields within packages
804        is broken because INI_FIELDS (where READ_CHECKPOINT is
805        called) is called *before* PACKAGES_INIT_VARIABLES.
806        This seems to be backwards since
807        1) its important to initially zero the entire field including
808           the "halo" region
809        2) zeroing needs to be done *before* reading pickup info
810           and the pickup call might or might not happen in any
811           particular run
812      - this needs an overhaul for R2
813    o cleanup verification/*/code/GMREDI_OPTIONS.h
814    o cleanup testreport

824    o cleaning some ALLOW_TANGENTLINEAR_RUN -> ALLOW_AUTODIFF
825    o bug fix in find_alpha.F for MDJWF:
826      - modif. to alpha = 1/D*( dN/dT - rho*dD/Dt) to account for
827        change rho -> rho-rhoConst
828      - replace call find_rho to find_rhonum
829    o initialisation of rFlx extended to full array (required by TAF)
830      and shifted to thermodynamics
831    o removed PTRACERS.h in ptracers routine

851         global_ocean.cs32x15, and global_with_exf)
852    o added surface flux output variables to TIMEAVE_STATVARS
