4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o model/src + pkg/momentum:
8      - add input files for  2-D additional Western and Southern cell-edge wall
9         (e.g., to add "thin-wall" where it is =1).
10      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
11        using 2nd hFacZ that is computed from initial (fix domain) hFac
12      - known limitations of thin wall implementation: not yet coded for sigma
13        coords; not working with CD-scheme neither.
14    o pkg/seaice:
15      - rename recently introduced parameters from (wrong name) AB to
16        BDF (backward difference time discretisation)
17      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
18    o tools/adjoint_options:
19      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
20    
21    checkpoint64t (2014/02/01)
22    o pkg/thsice
23      - corrected store directive fixes thsice adjoint gradient checks
24    o genmake2 & testreport:
25      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
26        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
27        Update testreport accordingly. No need to set "export OPENAD=true"
28        in adjoint_options/adjoint_oad anymore (will be removed later).
29    o pkg/shelfice:
30      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
31        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
32        so that surface forcing applies to k=kSurf if using pkg/shelfice.
33    o pkg/ctrl, pkg/grdchk, pkg/ecco:
34      - Changes to make GENARR more modular (i.e. invisible if not used)
35    o model/src/temp_integrate.F and salt_integrate.F
36      - re-include store directives that were removed on Dec 27th.
37    o model/src/external_forcing_surf.F
38      - add storage directives for EmPmR and PmEpR to avoid recomputation of
39        seaice_model in the adjoint that is problematic when seaice_model is
40        turned off in the adjoint. The resolved issue dated back to July when
41        EXTERNAL_FORCING_SURF call was moved.
42        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
43    o pkg/exf/exf_check.F
44      - fix a small bug again (originally found by Wentao Liu, now found again)
45      - streamline error output
46    o pkg/streamice and aim_v23:
47      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
48        Apple's /usr/bin/cpp knows what to do:
49        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
50        Target: x86_64-apple-darwin13.0.0
51    
52    checkpoint64s (2014/01/05)
53    o tools/adjoint_options:
54      - switch to fastopt.net TAF server (instead of default fastopt.de) for
55        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
56    o model/src:
57      - remove some unnecessary TAF storage directives in forward_step.F and
58        in dynamics.F (note: not always removed by TAF, e.g., double storage
59        of kappaRU,kappaRV in former version of dynamics.F).
60    o model/src & pkg/ptracers:
61      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
62        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
63        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
64      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
65      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
66      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
67    o useSingleCpuInput separates single-CPU input from single-CPU output;
68        for now only implemented for in exf_interp_read.F
69    o verification/advect_xy:
70      - fix missing EXCH call in local version of ini_salt.F and update output.
71    o momentum diagnostics:
72      - fix which deltaT is used in Total-Tendency diagnostics.
73      - fix typo in diagnostics for momentum tendency from AB.
74    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
75        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
76    
77    checkpoint64r (2013/12/08)
78    o verification/*/results:
79      - Update reference output of experiments that were passing with just 13 digits
80         (make it easier to detect future changes in results)
81    o model/src & pkg/ptracers:
82      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
83        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
84        to inside ptracers_integrate.F ; remove ptracers_advection.F
85    o coupling interface pkgs:
86        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
87      - change the config check to test the agreement of Ocean Depth
88        with ATM land/sea mask (instead of ATM orography);
89      - send to coupler the number of coupler time-steps to do for this run:
90        this allows to check for consistency and don't need anymore to be
91        specified in parameter file "data";
92      in coupler:
93      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
94      - improve report to log-file of config setting (pass log-file unit to few S/R)
95    o pkg/compon_communic:
96      - add coupling send/receive for non-tiled integer vector;
97      - add S/R to check and stop if any proc has an error (similar to
98        eesupp/src/stop_if_error.F but single thread and across Comm_World).
99    o pkg/exch2:
100      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
101        through list of all tiles my proc owns.
102    o model/src:
103      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
104        from rTrans) to simplify dependencies (no need to store rTrans anymore in
105        calling S/R); this affects AD results at machine truncation level:
106        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
107        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
108    o tools/build_options:
109      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
110    o coupling interface pkgs:
111        [compon_communic, atm_compon_interf & ocn_compon_interf]
112      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
113        to each S/R that needs it; remove un-used variables.
114      - change component tile registration (cpl_register.F in both compon_interf
115        and mitcomponent_tile_register.F) to pass the full list of tiles
116        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
117      - with pkg/exch2: adopt the same convention used for I/O to define mapping
118        towards coupler global array (unless W2_useE2ioLayOut=F):
119         a) can now use different tiling between atm & ocn comp.
120         b) no needs to modify the run-Off map when changing tiling (was needed
121            even if using the same tiling between atm & ocn).
122         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
123            full land tiles); not yet tested.
124      - check for valid mapping from comp. tile to coupler global array
125      - improve report of tile registration results to log file.
126    o pkg/exch2:
127      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
128        tile-registration (CPL_REGISTER);
129      - activate (un-comment) definition and setting of "W2_tileIndex" list to
130        store the local bi,bj indices of each tile;
131      - also print bi,bj in local report to log file;
132      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
133        Jun 2009 modif of pkg/exch2).
134    o testing on baudelaire:
135      - run 2 tests at a time: no significant slow down (since enough cpu) and
136        get the full set of test done earlier
137      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
138    o model/src/thermodynamics.F and routines called from it:
139      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
140        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
141        velocity (outp) by adding bolus velocity.
142      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
143        mass transport from velocity + lateral grid cell area
144      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
145      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
146     in thermodynamics.F
147      - remove k from thermodynamics.F and move it to temp_integrate.F
148        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
149        loop).
150      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
151        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
152        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
153        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
154      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
155        global_ocean.90x40x15, tutorial_global_oce_biogeo and
156        tutorial_tracer_adjsens (+ TLM output).
157    o tools/OAD_support and (verification/*/) code_oad:
158      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
159        module conversion ; remove unneeded CPP_EEOPTIONS.h.
160      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
161        version (closer to model/inc/CPP_OPTIONS.h).
162    o model/src:
163      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
164        retired list of parameters (routine FREEZE has been replace by surface
165        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
166    o pkg/gmredi:
167      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
168        velocity (same scheme but affects machine truncation) for GM_AdvForm.
169      - update output of FWD experiments: front_relax.bvp,
170        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
171    
172    checkpoint64q (2013/11/17)
173    o verification:
174      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
175        tutorial_global_oce_biogeo and global_ocean.90x40x15.
176      - generate new output (growth & melt) for seaice_itd experiment after
177        updating the input pickup_seaice files (previously wrong).
178    o pkg/cost:
179      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
180        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
181        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
182          cannot be applied to var in common block).
183        o allows to get results independent of tile-per-proc setting (if using
184          slower GLOBAL_SUM_SEND_RECV option).
185      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
186        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
187        forward gradients: update output).
188      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
189        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
190    o pkg/mom_common:
191      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
192        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
193        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
194        ensure that all field value that are used are set.
195    o tutorial_deep_convection (smag3d):
196      - add missing scaling in mom_calc_smag_3d.F;
197      - set smag3D_coeff in input.smag3d such that results do not change.
198    o pkg/dic:
199      - change dic_cost.F to compute cost on each tile first and then apply
200        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
201        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
202      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
203    o eesupp/src & pkg/mdsio:
204      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
205        (from pkg/mdsio) since they are no longer used for tape IO.
206      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
207        (+ keep a copy in pkg/atm_ocn_coupler).
208    o verification/isomip:
209      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
210    o tools/build_options:
211      - optfile linux_amd64_ifort11, fast (no ieee) case:
212        to get a working restart for all experiments, add "-fp-model source"
213        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
214    
215    checkpoint64p (2013/10/20)
216    o pkg/autodiff:
217      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
218        criteria, return to simple (default) tape IO format.
219    o pkg/mdsio (+ eesupp/src):
220      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
221        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
222      - fix globalFile and singleCpuIO options using simpler global mapping.
223      - new pairs of scatter/gather vector S/R (one for each type, generated from
224        template) corresponding to simpler global mapping.
225      - adread_write.F: switch to new S/R (but leave old calls commented) and write
226        to globalFile when parameter globalFiles is set to True.
227      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
228    o pkg/autodiff:
229      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
230        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
231        missing, just add a STOP if array type do not match.
232    o pkg/exf:
233      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
234         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
235         and rename array obsSIce to exf_iceFraction.
236    o tutorial_deep_convection:
237      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
238        for now all in this exp. code dir.
239      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
240        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
241    o eesupp/src:
242      - added SINGLE_DISK_IO option because reading of parameter files on
243        very large number of processors did not work with existing set-up
244    
245    checkpoint64o (2013/09/25)
246    o pkg/atm_phys & atm_compon_interf:
247      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
248    o tools/build_options:
249      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
250        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
251        remove CPP setting (was identical to genmake2 default).
252    o pkg/gmredi & model/src: Some updating and work done on the residual model.
253      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
254      - fixed up the calculation of the eddy stress and how it is added to the
255        external forcing via taueddy_external_forcing.F
256      - at the moment, it is very experimental and only works with the variable eddy
257        diffusivity calculated in gmredi_k3d.F
258    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
259        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
260    o testreport (& tools/do_tst_2+2):
261      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
262    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
263      - remove CPP='cpp -traditional -P' (this is genmake2 default)
264      - add switch (for big setups) to use 'medium' memory-model (but leave it
265        commented out for now). Note: needed with FC 19 to compile big setups.
266    o pkg/atm_compon_interf:
267      - regroup per field origin (model & pkgs) the coupling storage routines
268         (which accumalate in time each coupling field)
269      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
270        update accordingly + simplify aim_do_physics.F
271    
272    checkpoint64n (2013/08/26)
273    o pkg/bbl:
274      - update formulation to reduce dispersion of tracer properties in bbl
275      - replaced horizontal and vertical transport parameters with velocities
276      - changes results for verification/global_with_exf.yearly
277    o verification/halfpipe_streamice:
278      - change to matrix construction; update both Fwd & AD output.
279    o verification/tutorial_tracer_adjsens:
280      - OpenAD test: switch to vector-invariant momentum since fluxform with
281        rStar causes problems with OpenAD; update output.
282    o tools:
283      - genmake2: define a common prefix for all temp-file names ; move them
284        to local /tmp disk (but would be easy to move them back);
285      - xmakedepend: apply the same switch for temp-files.
286    o pkg/offline:
287      - changes for use with rStar (NLFS): assume that we continue to provide
288        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
289        output files) and apply r* scaling at each time-step (function of the time
290        varying Eta field); use normal pickup files (needed for restart with NLFS).
291    o adjoint with OpenAD:
292      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
293        package openad.  This package has to be compiled for all runs with OpenAD
294        instead of specifying code_oad_all as a modification directory.
295      - link the fortran templates from tools/OAD_support to the build directory
296        for preprocessing to avoid conflicts between different setups compiled
297        simultaneously and simplify cleanup.
298    o pkg/exf:
299      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
300        main model or other pkgs are exchanged in EXF_MAPFIELDS).
301    o model/src:
302      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
303        (similar to do_fields_blocking_exchanges.F).
304    o tools/genmake2:
305      - remove TAF output src code just before calling staf (when not doing a fresh
306        built, will stop if things go wrong with staf).
307      - fix target "adobj" (left from TAF version-2 transition)
308    o pkg/diagnostics:
309      - add a parameter to track the status of pkg/diagnostics activation;
310        this replace/extend the use of logical param "settingDiags" (to check
311        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
312        New S/R to print error message and stop when pkgStatus is not right.
313      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
314    
315    checkpoint64m (2013/08/13)
316    o model/inc:
317      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
318        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
319    o pkg/kpp & aim_v23:
320      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
321    o pkg/seaice:
322      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
323        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
324      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
325    o eesupp/src:
326      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
327        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
328    o switch to TAF version-2:
329      - add flow directives to "freeze" naming convention for ad-routines that
330        are used in I/O routines of adjoint state and associated common blocks
331        that are used in adcommon.h (backward compatible with version-1)
332      - update all ad-optfiles (in tools/adjoint_options + few local to some
333        verification exp) to switch to latest TAF version (currently 2.5.5);
334        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
335        out except for diva).
336      - the major change with TAF version-2 is that both the differentiated
337        routines and the forward routines (new) are returned as part of the TAF
338        output source code. Update genmake2 accordingly.
339      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
340        with version-2 when compared to TLM or FWD gradient); other experiments
341        output show minor changes (machine truncation level); update the few AD &
342        TLM output with 12 matching digits only (some prior to version-2 switch).

345    o model/src:
346      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
347      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
348        when using TAF but only if using OpenAD.
349    o pkg/mom_common+fluxform+vecinv:
350      - always set horiz. viscosity arrays to background value before calling
351        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
352        only when using variable horiz. viscosity (useVariableVisc=T);
353      - simplify mom_vecinv.F (only 1 block for momViscosity).
354    o pkg/mom_common: variable horiz. viscosity in NH code
355      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
356        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
357      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
358        useBiharmonicVisc & useVariableVisc.
359      - fix old bug (already in 1rst implementation of variable horizontal viscosity
360        in calc_gw.F, version 1.27, 2006/06/20):
361        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
362        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
363      - change background horiz viscosity in vertical momentum (gW) to always be
364        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
365        any type of variable viscosity, e.g., viscAh/4Grid)
366      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
367        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
368        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
369        default viscAh,viscA4 is zero).
370    o model/src:
371      - extend length of drC & recip_drC from Nr to Nr+1.
372  o Divided Adjoint (DIVA) with MPI:  o Divided Adjoint (DIVA) with MPI:
373    - genmake2: do not create local ./mpi_headers dir when no file to copy into.    - genmake2: do not create local ./mpi_headers dir when no file to copy into.
374    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
