4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/ecco:
8      - add runtime parameters mdt[start,end]date[1,2]
9      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
10    o pkg/seaice:
11      - make deltaC a global variable, so that it can be used in ridging code
12      - first step towards ridging: introduce new routines that compute
13        ice strength based on ridging parameters
14    o pkg/salt_plume + pkg/seaice/seaice_growth.F
15      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
16        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
17    o verification/hs94.1x64x5:
18      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
19      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
20    o autodiff:
21      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
22        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
23        For now, only in pkgs used in verification/hs94.1x64x5.
24      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
25        which are specific to TAF/TAMC).
26      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
27        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
28        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
29      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
30        building mitgcmuv_ad (make adAll).
31    o pkg/ecco:
32      - cost_gencost_seaicev4.F:
33         reformulate proxy cost as function of sst and local param SEAICE_freeze
34         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
35      - add stop statement if old names siv4-[sst,vol] are used
36      - add snapshots + cost reports for atmospheric longwave
37      - remove factor 0.1 in front of wtau[u,v]
38      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
39         ALLOW_TMI_SST_COST_CONTRIBUTION
40    o pkg/atm_phys:
41      - add some diagnostics for Short-wave and for convection S/R.
42    o pkg/seaice/seaice_growth:
43      - fix a bug in the lateral melt parameterization for SEAICE_ITD
44        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
45      - rearrange loop order for better vector code in the same code block
46      - rewrite the floeDiameter formula to have fewer divisions
47      -  (miraculously) none of this changes the results of seaice_itd
48    o pkg/smooth:
49      - move param smooth2Ddiffnbt to pkg/ecco
50    o pkg/salt_plume:
51      - salt_plume_frac.F:
52         clean up local param names
53         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
54    o pkg/rw:
55      - add RS version of S/R READ_MFLDS_LEV.
56    o pkg/streamice:
57      - fix the restart test by writing/reading pickup_streamice files.
58    o pkg/seaice:
59      - refine checks for jfnk-related parameters
60      - comment out if statement with SEAICEuseIMEX parameter as long as there
61        is no IMEX code to avoid confusion and surprises
62    
63    checkpoint64u (2014/03/07)
64    o verification/MLAdjust:
65      - rename secondary test suffix:
66         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
67         0.leithD -> AhFlxF  + switch to flux-form
68         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
69         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
70    o pkg/mom_vecinv:
71      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
72        to be before mom_calc_visc.F)
73      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
74      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
75        this is simpler for the adjoint and for diagnostics.
76    o model/src + pkg/momentum:
77      - add input files for  2-D additional Western and Southern cell-edge wall
78         (e.g., to add "thin-wall" where it is =1).
79      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
80        using 2nd hFacZ that is computed from initial (fix domain) hFac
81      - known limitations of thin wall implementation: not yet coded for sigma
82        coords; not working with CD-scheme neither.
83    o pkg/seaice:
84      - rename recently introduced parameters from (wrong name) AB to
85        BDF (backward difference time discretisation)
86      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
87    o tools/adjoint_options:
88      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
89    
90    checkpoint64t (2014/02/01)
91    o pkg/ecco
92      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
93        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
94      - replace hard-coded record number and period which only work for monthly
95        with read-in runtime param that works for other periods (month,day,year)
96    o pkg/thsice
97      - corrected store directive fixes thsice adjoint gradient checks
98    o genmake2 & testreport:
99      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
100        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
101        Update testreport accordingly. No need to set "export OPENAD=true"
102        in adjoint_options/adjoint_oad anymore (will be removed later).
103    o pkg/shelfice:
104      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
105        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
106        so that surface forcing applies to k=kSurf if using pkg/shelfice.
107    o pkg/ctrl, pkg/grdchk, pkg/ecco:
108      - Changes to make GENARR more modular (i.e. invisible if not used)
109    o model/src/temp_integrate.F and salt_integrate.F
110      - re-include store directives that were removed on Dec 27th.
111    o model/src/external_forcing_surf.F
112      - add storage directives for EmPmR and PmEpR to avoid recomputation of
113        seaice_model in the adjoint that is problematic when seaice_model is
114        turned off in the adjoint. The resolved issue dated back to July when
115        EXTERNAL_FORCING_SURF call was moved.
116        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
117    o pkg/exf/exf_check.F
118      - fix a small bug again (originally found by Wentao Liu, now found again)
119      - streamline error output
120    o pkg/streamice and aim_v23:
121      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
122        Apple's /usr/bin/cpp knows what to do:
123        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
124        Target: x86_64-apple-darwin13.0.0
125    
126    checkpoint64s (2014/01/05)
127    o tools/adjoint_options:
128      - switch to fastopt.net TAF server (instead of default fastopt.de) for
129        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
130    o model/src:
131      - remove some unnecessary TAF storage directives in forward_step.F and
132        in dynamics.F (note: not always removed by TAF, e.g., double storage
133        of kappaRU,kappaRV in former version of dynamics.F).
134    o model/src & pkg/ptracers:
135      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
136        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
137        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
138      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
139      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
140      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
141    o useSingleCpuInput separates single-CPU input from single-CPU output;
142        for now only implemented for in exf_interp_read.F
143    o verification/advect_xy:
144      - fix missing EXCH call in local version of ini_salt.F and update output.
145    o momentum diagnostics:
146      - fix which deltaT is used in Total-Tendency diagnostics.
147      - fix typo in diagnostics for momentum tendency from AB.
148    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
149        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
150    
151    checkpoint64r (2013/12/08)
152    o verification/*/results:
153      - Update reference output of experiments that were passing with just 13 digits
154         (make it easier to detect future changes in results)
155    o model/src & pkg/ptracers:
156      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
157        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
158        to inside ptracers_integrate.F ; remove ptracers_advection.F
159    o coupling interface pkgs:
160        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
161      - change the config check to test the agreement of Ocean Depth
162        with ATM land/sea mask (instead of ATM orography);
163      - send to coupler the number of coupler time-steps to do for this run:
164        this allows to check for consistency and don't need anymore to be
165        specified in parameter file "data";
166      in coupler:
167      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
168      - improve report to log-file of config setting (pass log-file unit to few S/R)
169    o pkg/compon_communic:
170      - add coupling send/receive for non-tiled integer vector;
171      - add S/R to check and stop if any proc has an error (similar to
172        eesupp/src/stop_if_error.F but single thread and across Comm_World).
173    o pkg/exch2:
174      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
175        through list of all tiles my proc owns.
176    o model/src:
177      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
178        from rTrans) to simplify dependencies (no need to store rTrans anymore in
179        calling S/R); this affects AD results at machine truncation level:
180        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
181        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
182    o tools/build_options:
183      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
184    o coupling interface pkgs:
185        [compon_communic, atm_compon_interf & ocn_compon_interf]
186      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
187        to each S/R that needs it; remove un-used variables.
188      - change component tile registration (cpl_register.F in both compon_interf
189        and mitcomponent_tile_register.F) to pass the full list of tiles
190        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
191      - with pkg/exch2: adopt the same convention used for I/O to define mapping
192        towards coupler global array (unless W2_useE2ioLayOut=F):
193         a) can now use different tiling between atm & ocn comp.
194         b) no needs to modify the run-Off map when changing tiling (was needed
195            even if using the same tiling between atm & ocn).
196         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
197            full land tiles); not yet tested.
198      - check for valid mapping from comp. tile to coupler global array
199      - improve report of tile registration results to log file.
200    o pkg/exch2:
201      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
202        tile-registration (CPL_REGISTER);
203      - activate (un-comment) definition and setting of "W2_tileIndex" list to
204        store the local bi,bj indices of each tile;
205      - also print bi,bj in local report to log file;
206      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
207        Jun 2009 modif of pkg/exch2).
208    o testing on baudelaire:
209      - run 2 tests at a time: no significant slow down (since enough cpu) and
210        get the full set of test done earlier
211      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
212    o model/src/thermodynamics.F and routines called from it:
213      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
214        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
215        velocity (outp) by adding bolus velocity.
216      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
217        mass transport from velocity + lateral grid cell area
218      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
219      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
220     in thermodynamics.F
221      - remove k from thermodynamics.F and move it to temp_integrate.F
222        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
223        loop).
224      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
225        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
226        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
227        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
228      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
229        global_ocean.90x40x15, tutorial_global_oce_biogeo and
230        tutorial_tracer_adjsens (+ TLM output).
231    o tools/OAD_support and (verification/*/) code_oad:
232      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
233        module conversion ; remove unneeded CPP_EEOPTIONS.h.
234      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
235        version (closer to model/inc/CPP_OPTIONS.h).
236    o model/src:
237      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
238        retired list of parameters (routine FREEZE has been replace by surface
239        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
240    o pkg/gmredi:
241      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
242        velocity (same scheme but affects machine truncation) for GM_AdvForm.
243      - update output of FWD experiments: front_relax.bvp,
244        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
245    
246    checkpoint64q (2013/11/17)
247    o verification:
248      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
249        tutorial_global_oce_biogeo and global_ocean.90x40x15.
250      - generate new output (growth & melt) for seaice_itd experiment after
251        updating the input pickup_seaice files (previously wrong).
252    o pkg/cost:
253      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
254        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
255        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
256          cannot be applied to var in common block).
257        o allows to get results independent of tile-per-proc setting (if using
258          slower GLOBAL_SUM_SEND_RECV option).
259      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
260        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
261        forward gradients: update output).
262      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
263        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
264    o pkg/mom_common:
265      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
266        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
267        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
268        ensure that all field value that are used are set.
269    o tutorial_deep_convection (smag3d):
270      - add missing scaling in mom_calc_smag_3d.F;
271      - set smag3D_coeff in input.smag3d such that results do not change.
272    o pkg/dic:
273      - change dic_cost.F to compute cost on each tile first and then apply
274        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
275        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
276      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
277    o eesupp/src & pkg/mdsio:
278      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
279        (from pkg/mdsio) since they are no longer used for tape IO.
280      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
281        (+ keep a copy in pkg/atm_ocn_coupler).
282    o verification/isomip:
283      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
284    o tools/build_options:
285      - optfile linux_amd64_ifort11, fast (no ieee) case:
286        to get a working restart for all experiments, add "-fp-model source"
287        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
288    
289    checkpoint64p (2013/10/20)
290    o pkg/autodiff:
291      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
292        criteria, return to simple (default) tape IO format.
293    o pkg/mdsio (+ eesupp/src):
294      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
295        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
296      - fix globalFile and singleCpuIO options using simpler global mapping.
297      - new pairs of scatter/gather vector S/R (one for each type, generated from
298        template) corresponding to simpler global mapping.
299      - adread_write.F: switch to new S/R (but leave old calls commented) and write
300        to globalFile when parameter globalFiles is set to True.
301      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
302    o pkg/autodiff:
303      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
304        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
305        missing, just add a STOP if array type do not match.
306    o pkg/exf:
307      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
308         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
309         and rename array obsSIce to exf_iceFraction.
310    o tutorial_deep_convection:
311      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
312        for now all in this exp. code dir.
313      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
314        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
315    o eesupp/src:
316      - added SINGLE_DISK_IO option because reading of parameter files on
317        very large number of processors did not work with existing set-up
318    
319    checkpoint64o (2013/09/25)
320    o pkg/atm_phys & atm_compon_interf:
321      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
322    o tools/build_options:
323      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
324        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
325        remove CPP setting (was identical to genmake2 default).
326    o pkg/gmredi & model/src: Some updating and work done on the residual model.
327      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
328      - fixed up the calculation of the eddy stress and how it is added to the
329        external forcing via taueddy_external_forcing.F
330      - at the moment, it is very experimental and only works with the variable eddy
331        diffusivity calculated in gmredi_k3d.F
332    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
333        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
334    o testreport (& tools/do_tst_2+2):
335      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
336    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
337      - remove CPP='cpp -traditional -P' (this is genmake2 default)
338      - add switch (for big setups) to use 'medium' memory-model (but leave it
339        commented out for now). Note: needed with FC 19 to compile big setups.
340    o pkg/atm_compon_interf:
341      - regroup per field origin (model & pkgs) the coupling storage routines
342         (which accumalate in time each coupling field)
343      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
344        update accordingly + simplify aim_do_physics.F
345    
346    checkpoint64n (2013/08/26)
347    o pkg/bbl:
348      - update formulation to reduce dispersion of tracer properties in bbl
349      - replaced horizontal and vertical transport parameters with velocities
350      - changes results for verification/global_with_exf.yearly
351    o verification/halfpipe_streamice:
352      - change to matrix construction; update both Fwd & AD output.
353    o verification/tutorial_tracer_adjsens:
354      - OpenAD test: switch to vector-invariant momentum since fluxform with
355        rStar causes problems with OpenAD; update output.
356    o tools:
357      - genmake2: define a common prefix for all temp-file names ; move them
358        to local /tmp disk (but would be easy to move them back);
359      - xmakedepend: apply the same switch for temp-files.
360    o pkg/offline:
361      - changes for use with rStar (NLFS): assume that we continue to provide
362        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
363        output files) and apply r* scaling at each time-step (function of the time
364        varying Eta field); use normal pickup files (needed for restart with NLFS).
365    o adjoint with OpenAD:
366      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
367        package openad.  This package has to be compiled for all runs with OpenAD
368        instead of specifying code_oad_all as a modification directory.
369      - link the fortran templates from tools/OAD_support to the build directory
370        for preprocessing to avoid conflicts between different setups compiled
371        simultaneously and simplify cleanup.
372    o pkg/exf:
373      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
374        main model or other pkgs are exchanged in EXF_MAPFIELDS).
375    o model/src:
376      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
377        (similar to do_fields_blocking_exchanges.F).
378    o tools/genmake2:
379      - remove TAF output src code just before calling staf (when not doing a fresh
380        built, will stop if things go wrong with staf).
381      - fix target "adobj" (left from TAF version-2 transition)
382    o pkg/diagnostics:
383      - add a parameter to track the status of pkg/diagnostics activation;
384        this replace/extend the use of logical param "settingDiags" (to check
385        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
386        New S/R to print error message and stop when pkgStatus is not right.
387      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
388    
389    checkpoint64m (2013/08/13)
390    o model/inc:
391      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
392        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
393    o pkg/kpp & aim_v23:
394      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
395    o pkg/seaice:
396      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
397        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
398      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
399    o eesupp/src:
400      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
401        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
402    o switch to TAF version-2:
403      - add flow directives to "freeze" naming convention for ad-routines that
404        are used in I/O routines of adjoint state and associated common blocks
405        that are used in adcommon.h (backward compatible with version-1)
406      - update all ad-optfiles (in tools/adjoint_options + few local to some
407        verification exp) to switch to latest TAF version (currently 2.5.5);
408        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
409        out except for diva).
410      - the major change with TAF version-2 is that both the differentiated
411        routines and the forward routines (new) are returned as part of the TAF
412        output source code. Update genmake2 accordingly.
413      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
414        with version-2 when compared to TLM or FWD gradient); other experiments
415        output show minor changes (machine truncation level); update the few AD &
416        TLM output with 12 matching digits only (some prior to version-2 switch).
417    
418    checkpoint64l (2013/08/05)
419    o model/src:
420      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
421      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
422        when using TAF but only if using OpenAD.
423    o pkg/mom_common+fluxform+vecinv:
424      - always set horiz. viscosity arrays to background value before calling
425        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
426        only when using variable horiz. viscosity (useVariableVisc=T);
427      - simplify mom_vecinv.F (only 1 block for momViscosity).
428    o pkg/mom_common: variable horiz. viscosity in NH code
429      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
430        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
431      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
432        useBiharmonicVisc & useVariableVisc.
433      - fix old bug (already in 1rst implementation of variable horizontal viscosity
434        in calc_gw.F, version 1.27, 2006/06/20):
435        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
436        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
437      - change background horiz viscosity in vertical momentum (gW) to always be
438        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
439        any type of variable viscosity, e.g., viscAh/4Grid)
440      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
441        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
442        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
443        default viscAh,viscA4 is zero).
444    o model/src:
445      - extend length of drC & recip_drC from Nr to Nr+1.
446    o Divided Adjoint (DIVA) with MPI:
447      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
448      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
449        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
450    
451    checkpoint64k (2013/07/23)
452    o tools/OAD_support:
453      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
454        and remove it from genmake2.
455    o tools/build_options:
456      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
457        MPI_HEADER_FILES list (let genmake2 find the missing headers)
458    o verification/halfpipe_streamice:
459      - change to driving stress formulation; update both Fwd & AD output.
460    o tools/genmake2 and Divided Adjoint with MPI:
461      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
462      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
463      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
464        Makefile, which is set by genmake2, and check which mpi-headers are needed.
465        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
466      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
467    o testreport:
468      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
469        perform additional runs (number of additional runs is "add_DIVA_runs" taken
470        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
471    o verification/lab_sea (AD test):
472      - change to test Divided Adjoint Run in this set-up (both standard AD test
473        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
474    o pkg atm_ & ocn_compon_interf:
475      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
476        staggerTimeStep implementation) and disable (retired) corresponding
477        parameter.
478    o pkg/offline:
479      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
480      - add S/R OFFLINE_CHECK to print offline parameter summary
481        and stop if loading a file that is not used;
482      - enable to calculate GMRedi tensor, KPP mixing and convective index
483        when the corresponding file(s) is/are not specified (but pkg is used).
484      - comment out resetting of monitorFreq (to endTime) since it still useful
485        for monitoring CFL numbers and checking offline fields.
486    o OpenAD:
487      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
488        smaller standard output) and generate new (smaller) output (on baudelaire
489        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
490    o model/src:
491      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
492        (where external_forcing_adjust was called) and change list of arguments;
493      - merge external_forcing_adjust.F into external_forcing_surf.F
494      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
495        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
496        previously in file "balance_relax.F", now removed); remove corresponding
497        arrays in FFIELDS.h.
498      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
499        a hack for getting back surfaceForcingS (loaded from file) when using
500        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
501      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
502        (was getting only 11 digits for AD-grad, due to different truncation
503         error in AD code).
504    
505    checkpoint64j (2013/07/04)
506    o pkg/offline:
507      - to enable the use of other features with pkg offline (e.g., obcs),
508        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
509      - comment out "allowFreezing" (now active) in 2 offline testing exp.
510    o pkg/exf ALLOW_RUNOFTEMP
511      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
512      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
513      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
514    o pkg/atm_phys:
515      - allows to add some damping on uVel,vVel (strength only function of k).
516    o verification, ad-tests:
517      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
518        global_ocean_ebm and offline_exf_seaice.thsice.
519    o verification/halfpipe_streamice:
520      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
521        flux input boundary conditions to be ignored; a fix for this bug changed
522        verification results for forward test.
523      - add adjoint test.
524    o pkg/ptracers:
525      - allow to restart without SOM pickup (resetting SOM to zero).
526    o pkg/gmredi:
527      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
528      - It uses mixing length theory and suppression by steering level effects to
529        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
530        to JPO, for more details).
531      - It also uses the diffusivity to calculate an eddy induced streamfunction
532        based on a PV closure (rather than a buoyancy closure as in GM).
533      - New files added to pkg/gmredi:
534        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
535          induced overturning streamfunction (called from gmredi_calc_tensor)
536        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
537          for use in gmredi_k3d
538        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
539          the eddy diffusivity
540    
541    checkpoint64i (2013/06/18)
542    o pkg/cheapaml:
543      - take src files from MITgcm_contrib/verification_other/offline_cheapaml/code
544        that enable the use of seaice (pkg/thsice thermo & pkg/seaice dynamics)
545        with pkg/cheapaml.
546    o utils/python: add subpackage for cubed sphere function, first example is
547        simple cs.pcol to plot 2D fields on a map
548    o pkg/streamice:
549      - This is a new package in MITgcm, which solves dynamic equations for ice
550         sheets and ice streams
551      - At the moment it is independent of atmosphere/ocean dynamics, or any
552        other physical packages in MITgcm, even ShelfIce (although it is anticipat-
553        ed that this will change)
554      - There is a new verification exercise that tests it, halfpipe_streamice,
555        evolves a 40x80 km ice stream/ice shelf (at coarse resolution) in a
556        rectangular embayment
557      - halfpipe_streamice is forward-only for now, will have TAF test soon
558      - for questions, email dgoldber@mit.edu
559    o pkg/thsice:
560      - fix filling of snow-precip diagnostic (SIsnwPrc) (left from the removing
561        of snowPrc from common bloc, on May 2nd, thsice_step_fwd.F revision 1.40);
562      - remove diagnostics 'SI_FrcFx' ( now identical to 'SI_Fract' with new
563         call sequence: ice-Thermo(thsice),ice-Dyn,ice-Advect );
564      - allow precip from pkg/cheapaml to make snow over seaice.
565    o pkg/cfc:
566      - move in separated header file (CFC_ATMOS.h) time-serie arrays of Atmos CFC
567      - remove atmos CFC 2-D arrays from common bloc (now local variables)
568      - change some hard-coded constant to run time parameter for reading and
569        and interpolating atmospheric CFC ; keep same default as previously.
570      - more flexible reading of Atmos CFC (number of records no longer hard-coded)
571      - put arguments in standard order: myTime, myIter, myThid
572      - use standard S/R GET_PERIODIC_INTERVAL for time interpolation of
573        atmospheric CFC ; fix for the case myIter < PTRACERS_iter0.
574      - fix calculation of surf tendencys for partial-cell and/or Non-Lin Free-Surf
575      - new routine to print summary of CFC params and check for consistency.
576    o pkg/seaice: add uice/vice to the parameter list of s/r seaice_advdiff,
577      similar to thsice_advdiff.
578      Note that for the B-grid case the routine parameters uc/vc are overwritten.
579    o pkg/cfc:
580      - change time interpolation for atmospheric CFC-11 (now same as for CFC-12);
581        update output (CFC-11) of experiment cfc_example and tutorial_cfc_offline.
582      - fix interpolation of atmphspheric CFC between Sorthern and Northern
583        hemisphere value.
584    o pkg/seaice:
585      - allow to use seaice dynamics without pkg/exf (e.g., using pkg/cheapaml)
586    o pkg/seaice: add Adams-Bashforth2 time discretization for ice dynamics;
587                  so far only for JFNK-solver, turn on with SEAICEuseAB2 = .TRUE.
588      - requires an additional time level that is stored in the pickup
589      - you can start with AB2 from a pickup without this time level with
590        pickupStrictlyMatch = .false.
591    
592    checkpoint64h (2013/05/26)
593    o pkg/cheapaml:
594      - replace one ()**.5 with SQRT + use temp var "cdu = tau/Du" (coare3_flux);
595        affect machine truncation (but exp cheapAML_box still pass with 13 digits).
596      - consistent treatment of uWind,vWind location: assume everywhere in
597        pkg/cheapaml that they are on C-grid (@ uVel,vVel location)
598        (Note: was already the case for Tair,Qair advection);
599        add option (INCONSISTENT_WIND_LOCATION) to recover old results.
600      - compute diabatic forcing only in the interior (excluding overlap regions)
601      - fill in array "Qsw" (for short-wave heating);
602      - add diagnostic for precip ; fill-in diagnostics for cheapAML state vars
603        before any update (consistent with MITgcm state var diagnostics);
604      - cheapaml_fields_load.F & cheapaml_init_varia.F : only fill outer edges if
605        non periodic ; + adjusted for uWind,vWind (C-grid).
606    o pkg/seaice:
607      - remove dependence of pkg/seaice versus pkg/exf (file: pkg/pkg_depend) and
608        add explicitly pkg/exf in experiments that currently use pkg/seaice.
609      - allows to compile pkg/seaice without pkg/exf.
610    o tools/OAD_support:
611      - use a local copy (ourRWCPinBd) to ensure index ourRWCP stays within bounds
612        of array "ourStepOf" in function rvNextAction (revolve.F90).
613    o pkg/aim_compon_interf renamed to pkg/atm_compon_interf
614      - change pkg name (to be used with other atmospheric physics pkg)
615        but by-pass CVS when making the new pkg so that we keep the CVS history.
616    o pkg/offline:
617      - call OFFLINE_FIELDS_LOAD from pkg/offline/offline_init_varia.F
618        (previously called from pkg/dic_surfforcing_init.F)
619    o model/src:
620      - re-order sequence of calls within packages_init_variables.F, using
621        standard order, except for:
622         DIAGNOSTICS_INIT_VARIA and OFFLINE_INIT_VARIA (called @ the top),
623         CTRL_MAP_INI and OBCS_INIT_VARIABLES (called @ the bottom)
624    o new pkg: atm_phys
625      - add entry point and source code (previously in contrib
626          verification_other/atm_gray/code_gray/) for new pkg "atm_phys"
627        (atmospheric physics pkg from P. O'Gorman and T. Schneider, JCl, 2008).
628      - re-order sequence of calls within packages_readparms.F,
629         packages_init_fixed.F and packages_write_pickup.F
630        (but skip packages_init_variables.F because of TAF issues).
631      - update contrib/*/atm_gray/ experiment.
632    o pkg/seaice (ITD code):
633      - simplify and fix the writing of pickup-files for ITD case
634    o pkg/seaice (ITD code):
635      - introduce floe size dependent lateral melt for ITD case;
636      - cleaning (avoid division by zero, change to f77 syntax, remove tabs)
637      - update seaice_itd experiment main output.
638    o pkg/thsice:
639      - remove snowPrc from common block THSICE_FLUX, in THSICE_VARS.h and
640        declared it locally (without bi,bj) in thsice_main.F & aim_do_physics.F;
641        changed accordingly pkg/atm2d.
642    
643    checkpoint64g (2013/05/01)
644    o pkg/exf ALLOW_RUNOFTEMP
645      - if defined,  river and glacier runoff temperature can be read-in from
646        runoftempfile; runoftempfile needs to have same format as runofffile
647    o pkg/thsice (& pkg/bulk_force):
648      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
649        for energy content of Precip + RunOff & Evap (like with pkg/exf).
650      - change computation domain to always be the interior (without overlap).
651      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
652    o verification/tutorial_global_oce_biogeo:
653      - add preliminary OpenAD setup (still has problems)
654    o pkg/seaice:
655      - turn some parameters for choosing the convergence criterion of
656        the inexact Newton method (JFNK) into runtime parameters for convenience
657      - clean up seaice_calc_viscosities.F: remove/retire two options for
658        SEAICetaZmethod (1,2), introduce area weighting for method 3; this changes
659        the results of lab_sea/input because a division has been replaced by
660        a multiplication with the reciprocal (sumNorm)
661      - modify offline_exf_seaice/input.dyn_jfnk/data.seaice to improve
662        convergence of solver (changes results, of course), and to test some
663        new features
664    o model/src:
665      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
666      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
667      - move forcing adjustment (balancing surface forcing) in specific S/R
668        where might also be applied exchanges (if needed) to forcing arrays.
669    o pkg/shelfice:
670      - allow to specify the Ice-Shelf mass per unit area (instead of
671        shelficeLoadAnomaly) and do the conversion from one to the other
672      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
673        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
674        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
675        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
676      - update isomip experiment forward output (get machine truncation error
677        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
678    o verification/offline_exf_seaice:
679      revise data.seaice in input.thermo and input_ad and update results accordingly
680        HO = 0.2, SEAICE_areaLossFormula = 2,
681        SEAICE_growMeltByConv = .TRUE.,
682        SEAICE_doOpenWaterMelt = .TRUE.,
683      Improve consistency with input.thsice and fix the spurious 500m ice corners
684    o verification/global_ocean.cs32x15:
685      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
686        in icedyn (thsice+seaice-dyn) test and update output.
687    o verification/offline_exf_seaice:
688      - adjust list of tested variables (with testreport) and update
689        standard test output with better slection of monitored fields.
690    o pkg/cd_code:
691      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
692        experiment lab_sea.hb87
693    o tools/genmake2:
694      - change default makedepend from the system default to tools/xmakedepend:
695        When no makedepend is specified, select tools/xmakedepend it the test pass,
696        otherwise select the system default (if exist and pass the test) or
697        try to build cyrus-makedepend ; stop if none of the 3 works.
698    o pkg/exf & pkg/thsice:
699      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
700        for energy content of Precip + RunOff & Evap. Assumes:
701       1) Rain has same temp as Air.
702       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
703       3) Run-Off comes at the temp of surface water (with same Cp)
704       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
705        put directly into Latent Heat flux & should use water-vapor heat capacity.
706       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
707        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
