4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/sbo:
8      - incorporate modifications from Katherine Quinn to enable the use of sbo
9        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
10        output for future testreport verification (unfinished).
11    o pkg/atm_phys:
12      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
13        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
14        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
15    o pkg/seaice
16      seaice_calc_ice_strength.F: modify expression to avoid divisions
17        (affects truncation)
18      seaice_do_ridging.F: clean up the insectarium
19      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
20      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
21      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
22      - add some debugging information and error messages (warnings)
23    o model/src: modifications relatd to atmosphere p*:
24      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
25      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
26        of vertical profile tRef in geopotential background and anomaly.
27      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
28        and pkg/atm_phys.
29      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
30        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
31    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
32    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
33        not used right now, but can be used in BGC packages to fix conservation.
34    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
35        other packages too.
36    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
37        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
38    o model/src:
39      - since we have several heat capacity (even in model/src), define "recip_Cp"
40        as local variable (no longer in common block) to avoid any confusion.
41      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
42    o pkg/exf:
43      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
44        air density as function of air Temp, Humidity and atm pressure.
45    
46    checkpoint64w (2014/05/02)
47    o verification:
48      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
49        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
50        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
51        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
52        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
53    o model/src: for atmosphere in p* coords:
54      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
55      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
56        but not yet activated.
57    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
58      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
59      - this changes the results (but not for any verification experiment, because
60        none tests this), but avoids having an extra field in the restart files
61    o pkg/seaice: remove global variable TICE (not needed)
62      - replace by TICES or local variable where necessary (cost_seaice_test,
63        seaice_diagnostics_state)
64      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
65      - use specific read/write routines for reading and writing individual leves
66        of a multilevel field
67    o pkg/ctrl & model/inc:
68      - move additional anomaly fields of control vars (related to options:
69         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
70        from DYNVARS.h into new header file: CTRL_FIELDS.h
71    o pkg/seaice: some small modifications to the ridging code
72      - make fw2ObyRidge a global variable and add the freshwater flux to
73        seaice_growth
74      - pass actual thickness from seaice_prepare_ridging, so that it is
75        computed only in one place and compute it in the same way as in
76        seaice_growth
77      - initialise more fields in seaice_do_ridging that where cause floating
78        point exceptions over land
79    o pkg/seaice: preparations for ridging code and first real ridging code
80      - move most of "PART 1" of S/R seaice_growth into a new and separate
81        S/R seaice_reg_ridge that will both regularize the state variable after
82        advection call the actual ridging routine;
83      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
84        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
85      - remove ridging code from seaice_advdiff
86      - clean up remaining part 1 of seaice_growth in an attempt to make it
87        more readable (this is probably subjective)
88      - call seaice_itd_redist once in the initialisation phase to have the initial
89        conditions in the correct category
90      - finally: add new ridging routine for ITD code
91    
92    checkpoint64v (2014/04/11)
93    o pkg/ecco:
94      - add runtime parameters mdt[start,end]date[1,2]
95      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
96    o pkg/seaice:
97      - make deltaC a global variable, so that it can be used in ridging code
98      - first step towards ridging: introduce new routines that compute
99        ice strength based on ridging parameters
100      - add diagnostic for HSNOWITD
101      - add opnWtrFrac as a global variable (required for ridging scheme)
102    o pkg/salt_plume + pkg/seaice/seaice_growth.F
103      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
104        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
105    o verification/hs94.1x64x5:
106      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
107      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
108    o autodiff:
109      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
110        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
111        For now, only in pkgs used in verification/hs94.1x64x5.
112      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
113        which are specific to TAF/TAMC).
114      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
115        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
116        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
117      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
118        building mitgcmuv_ad (make adAll).
119    o pkg/ecco:
120      - cost_gencost_seaicev4.F:
121         reformulate proxy cost as function of sst and local param SEAICE_freeze
122         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
123      - add stop statement if old names siv4-[sst,vol] are used
124      - add snapshots + cost reports for atmospheric longwave
125      - remove factor 0.1 in front of wtau[u,v]
126      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
127         ALLOW_TMI_SST_COST_CONTRIBUTION
128    o pkg/atm_phys:
129      - add some diagnostics for Short-wave and for convection S/R.
130    o pkg/seaice/seaice_growth:
131      - fix a bug in the lateral melt parameterization for SEAICE_ITD
132        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
133      - rearrange loop order for better vector code in the same code block
134      - rewrite the floeDiameter formula to have fewer divisions
135      -  (miraculously) none of this changes the results of seaice_itd
136    o pkg/smooth:
137      - move param smooth2Ddiffnbt to pkg/ecco
138    o pkg/salt_plume:
139      - salt_plume_frac.F:
140         clean up local param names
141         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
142    o pkg/rw:
143      - add RS version of S/R READ_MFLDS_LEV.
144    o pkg/streamice:
145      - fix the restart test by writing/reading pickup_streamice files.
146    o pkg/seaice:
147      - refine checks for jfnk-related parameters
148      - comment out if statement with SEAICEuseIMEX parameter as long as there
149        is no IMEX code to avoid confusion and surprises
150    
151    checkpoint64u (2014/03/07)
152    o verification/MLAdjust:
153      - rename secondary test suffix:
154         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
155         0.leithD -> AhFlxF  + switch to flux-form
156         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
157         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
158    o pkg/mom_vecinv:
159      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
160        to be before mom_calc_visc.F)
161      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
162      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
163        this is simpler for the adjoint and for diagnostics.
164    o model/src + pkg/momentum:
165      - add input files for  2-D additional Western and Southern cell-edge wall
166         (e.g., to add "thin-wall" where it is =1).
167      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
168        using 2nd hFacZ that is computed from initial (fix domain) hFac
169      - known limitations of thin wall implementation: not yet coded for sigma
170        coords; not working with CD-scheme neither.
171    o pkg/seaice:
172      - rename recently introduced parameters from (wrong name) AB to
173        BDF (backward difference time discretisation)
174      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
175    o tools/adjoint_options:
176      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
177    
178    checkpoint64t (2014/02/01)
179    o pkg/ecco
180      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
181        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
182      - replace hard-coded record number and period which only work for monthly
183        with read-in runtime param that works for other periods (month,day,year)
184    o pkg/thsice
185      - corrected store directive fixes thsice adjoint gradient checks
186    o genmake2 & testreport:
187      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
188        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
189        Update testreport accordingly. No need to set "export OPENAD=true"
190        in adjoint_options/adjoint_oad anymore (will be removed later).
191    o pkg/shelfice:
192      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
193        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
194        so that surface forcing applies to k=kSurf if using pkg/shelfice.
195    o pkg/ctrl, pkg/grdchk, pkg/ecco:
196      - Changes to make GENARR more modular (i.e. invisible if not used)
197    o model/src/temp_integrate.F and salt_integrate.F
198      - re-include store directives that were removed on Dec 27th.
199    o model/src/external_forcing_surf.F
200      - add storage directives for EmPmR and PmEpR to avoid recomputation of
201        seaice_model in the adjoint that is problematic when seaice_model is
202        turned off in the adjoint. The resolved issue dated back to July when
203        EXTERNAL_FORCING_SURF call was moved.
204        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
205    o pkg/exf/exf_check.F
206      - fix a small bug again (originally found by Wentao Liu, now found again)
207      - streamline error output
208    o pkg/streamice and aim_v23:
209      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
210        Apple's /usr/bin/cpp knows what to do:
211        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
212        Target: x86_64-apple-darwin13.0.0
213    
214    checkpoint64s (2014/01/05)
215    o tools/adjoint_options:
216      - switch to fastopt.net TAF server (instead of default fastopt.de) for
217        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
218    o model/src:
219      - remove some unnecessary TAF storage directives in forward_step.F and
220        in dynamics.F (note: not always removed by TAF, e.g., double storage
221        of kappaRU,kappaRV in former version of dynamics.F).
222    o model/src & pkg/ptracers:
223      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
224        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
225        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
226      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
227      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
228      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
229    o useSingleCpuInput separates single-CPU input from single-CPU output;
230        for now only implemented for in exf_interp_read.F
231    o verification/advect_xy:
232      - fix missing EXCH call in local version of ini_salt.F and update output.
233    o momentum diagnostics:
234      - fix which deltaT is used in Total-Tendency diagnostics.
235      - fix typo in diagnostics for momentum tendency from AB.
236    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
237        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
238    
239    checkpoint64r (2013/12/08)
240    o verification/*/results:
241      - Update reference output of experiments that were passing with just 13 digits
242         (make it easier to detect future changes in results)
243    o model/src & pkg/ptracers:
244      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
245        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
246        to inside ptracers_integrate.F ; remove ptracers_advection.F
247    o coupling interface pkgs:
248        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
249      - change the config check to test the agreement of Ocean Depth
250        with ATM land/sea mask (instead of ATM orography);
251      - send to coupler the number of coupler time-steps to do for this run:
252        this allows to check for consistency and don't need anymore to be
253        specified in parameter file "data";
254      in coupler:
255      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
256      - improve report to log-file of config setting (pass log-file unit to few S/R)
257    o pkg/compon_communic:
258      - add coupling send/receive for non-tiled integer vector;
259      - add S/R to check and stop if any proc has an error (similar to
260        eesupp/src/stop_if_error.F but single thread and across Comm_World).
261    o pkg/exch2:
262      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
263        through list of all tiles my proc owns.
264    o model/src:
265      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
266        from rTrans) to simplify dependencies (no need to store rTrans anymore in
267        calling S/R); this affects AD results at machine truncation level:
268        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
269        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
270    o tools/build_options:
271      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
272    o coupling interface pkgs:
273        [compon_communic, atm_compon_interf & ocn_compon_interf]
274      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
275        to each S/R that needs it; remove un-used variables.
276      - change component tile registration (cpl_register.F in both compon_interf
277        and mitcomponent_tile_register.F) to pass the full list of tiles
278        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
279      - with pkg/exch2: adopt the same convention used for I/O to define mapping
280        towards coupler global array (unless W2_useE2ioLayOut=F):
281         a) can now use different tiling between atm & ocn comp.
282         b) no needs to modify the run-Off map when changing tiling (was needed
283            even if using the same tiling between atm & ocn).
284         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
285            full land tiles); not yet tested.
286      - check for valid mapping from comp. tile to coupler global array
287      - improve report of tile registration results to log file.
288    o pkg/exch2:
289      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
290        tile-registration (CPL_REGISTER);
291      - activate (un-comment) definition and setting of "W2_tileIndex" list to
292        store the local bi,bj indices of each tile;
293      - also print bi,bj in local report to log file;
294      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
295        Jun 2009 modif of pkg/exch2).
296    o testing on baudelaire:
297      - run 2 tests at a time: no significant slow down (since enough cpu) and
298        get the full set of test done earlier
299      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
300    o model/src/thermodynamics.F and routines called from it:
301      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
302        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
303        velocity (outp) by adding bolus velocity.
304      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
305        mass transport from velocity + lateral grid cell area
306      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
307      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
308     in thermodynamics.F
309      - remove k from thermodynamics.F and move it to temp_integrate.F
310        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
311        loop).
312      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
313        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
314        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
315        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
316      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
317        global_ocean.90x40x15, tutorial_global_oce_biogeo and
318        tutorial_tracer_adjsens (+ TLM output).
319    o tools/OAD_support and (verification/*/) code_oad:
320      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
321        module conversion ; remove unneeded CPP_EEOPTIONS.h.
322      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
323        version (closer to model/inc/CPP_OPTIONS.h).
324    o model/src:
325      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
326        retired list of parameters (routine FREEZE has been replace by surface
327        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
328    o pkg/gmredi:
329      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
330        velocity (same scheme but affects machine truncation) for GM_AdvForm.
331      - update output of FWD experiments: front_relax.bvp,
332        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
333    
334    checkpoint64q (2013/11/17)
335    o verification:
336      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
337        tutorial_global_oce_biogeo and global_ocean.90x40x15.
338      - generate new output (growth & melt) for seaice_itd experiment after
339        updating the input pickup_seaice files (previously wrong).
340    o pkg/cost:
341      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
342        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
343        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
344          cannot be applied to var in common block).
345        o allows to get results independent of tile-per-proc setting (if using
346          slower GLOBAL_SUM_SEND_RECV option).
347      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
348        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
349        forward gradients: update output).
350      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
351        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
352    o pkg/mom_common:
353      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
354        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
355        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
356        ensure that all field value that are used are set.
357    o tutorial_deep_convection (smag3d):
358      - add missing scaling in mom_calc_smag_3d.F;
359      - set smag3D_coeff in input.smag3d such that results do not change.
360    o pkg/dic:
361      - change dic_cost.F to compute cost on each tile first and then apply
362        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
363        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
364      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
365    o eesupp/src & pkg/mdsio:
366      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
367        (from pkg/mdsio) since they are no longer used for tape IO.
368      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
369        (+ keep a copy in pkg/atm_ocn_coupler).
370    o verification/isomip:
371      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
372    o tools/build_options:
373      - optfile linux_amd64_ifort11, fast (no ieee) case:
374        to get a working restart for all experiments, add "-fp-model source"
375        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
376    
377    checkpoint64p (2013/10/20)
378    o pkg/autodiff:
379      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
380        criteria, return to simple (default) tape IO format.
381    o pkg/mdsio (+ eesupp/src):
382      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
383        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
384      - fix globalFile and singleCpuIO options using simpler global mapping.
385      - new pairs of scatter/gather vector S/R (one for each type, generated from
386        template) corresponding to simpler global mapping.
387      - adread_write.F: switch to new S/R (but leave old calls commented) and write
388        to globalFile when parameter globalFiles is set to True.
389      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
390    o pkg/autodiff:
391      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
392        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
393        missing, just add a STOP if array type do not match.
394    o pkg/exf:
395      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
396         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
397         and rename array obsSIce to exf_iceFraction.
398    o tutorial_deep_convection:
399      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
400        for now all in this exp. code dir.
401      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
402        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
403    o eesupp/src:
404      - added SINGLE_DISK_IO option because reading of parameter files on
405        very large number of processors did not work with existing set-up
406    
407    checkpoint64o (2013/09/25)
408    o pkg/atm_phys & atm_compon_interf:
409      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
410    o tools/build_options:
411      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
412        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
413        remove CPP setting (was identical to genmake2 default).
414    o pkg/gmredi & model/src: Some updating and work done on the residual model.
415      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
416      - fixed up the calculation of the eddy stress and how it is added to the
417        external forcing via taueddy_external_forcing.F
418      - at the moment, it is very experimental and only works with the variable eddy
419        diffusivity calculated in gmredi_k3d.F
420    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
421        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
422    o testreport (& tools/do_tst_2+2):
423      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
424    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
425      - remove CPP='cpp -traditional -P' (this is genmake2 default)
426      - add switch (for big setups) to use 'medium' memory-model (but leave it
427        commented out for now). Note: needed with FC 19 to compile big setups.
428    o pkg/atm_compon_interf:
429      - regroup per field origin (model & pkgs) the coupling storage routines
430         (which accumalate in time each coupling field)
431      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
432        update accordingly + simplify aim_do_physics.F
433    
434    checkpoint64n (2013/08/26)
435    o pkg/bbl:
436      - update formulation to reduce dispersion of tracer properties in bbl
437      - replaced horizontal and vertical transport parameters with velocities
438      - changes results for verification/global_with_exf.yearly
439    o verification/halfpipe_streamice:
440      - change to matrix construction; update both Fwd & AD output.
441    o verification/tutorial_tracer_adjsens:
442      - OpenAD test: switch to vector-invariant momentum since fluxform with
443        rStar causes problems with OpenAD; update output.
444    o tools:
445      - genmake2: define a common prefix for all temp-file names ; move them
446        to local /tmp disk (but would be easy to move them back);
447      - xmakedepend: apply the same switch for temp-files.
448    o pkg/offline:
449      - changes for use with rStar (NLFS): assume that we continue to provide
450        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
451        output files) and apply r* scaling at each time-step (function of the time
452        varying Eta field); use normal pickup files (needed for restart with NLFS).
453    o adjoint with OpenAD:
454      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
455        package openad.  This package has to be compiled for all runs with OpenAD
456        instead of specifying code_oad_all as a modification directory.
457      - link the fortran templates from tools/OAD_support to the build directory
458        for preprocessing to avoid conflicts between different setups compiled
459        simultaneously and simplify cleanup.
460    o pkg/exf:
461      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
462        main model or other pkgs are exchanged in EXF_MAPFIELDS).
463    o model/src:
464      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
465        (similar to do_fields_blocking_exchanges.F).
466    o tools/genmake2:
467      - remove TAF output src code just before calling staf (when not doing a fresh
468        built, will stop if things go wrong with staf).
469      - fix target "adobj" (left from TAF version-2 transition)
470    o pkg/diagnostics:
471      - add a parameter to track the status of pkg/diagnostics activation;
472        this replace/extend the use of logical param "settingDiags" (to check
473        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
474        New S/R to print error message and stop when pkgStatus is not right.
475      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
476    
477    checkpoint64m (2013/08/13)
478    o model/inc:
479      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
480        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
481    o pkg/kpp & aim_v23:
482      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
483    o pkg/seaice:
484      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
485        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
486      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
487    o eesupp/src:
488      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
489        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
490    o switch to TAF version-2:
491      - add flow directives to "freeze" naming convention for ad-routines that
492        are used in I/O routines of adjoint state and associated common blocks
493        that are used in adcommon.h (backward compatible with version-1)
494      - update all ad-optfiles (in tools/adjoint_options + few local to some
495        verification exp) to switch to latest TAF version (currently 2.5.5);
496        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
497        out except for diva).
498      - the major change with TAF version-2 is that both the differentiated
499        routines and the forward routines (new) are returned as part of the TAF
500        output source code. Update genmake2 accordingly.
501      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
502        with version-2 when compared to TLM or FWD gradient); other experiments
503        output show minor changes (machine truncation level); update the few AD &
504        TLM output with 12 matching digits only (some prior to version-2 switch).
505    
506    checkpoint64l (2013/08/05)
507    o model/src:
508      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
509      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
510        when using TAF but only if using OpenAD.
511    o pkg/mom_common+fluxform+vecinv:
512      - always set horiz. viscosity arrays to background value before calling
513        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
514        only when using variable horiz. viscosity (useVariableVisc=T);
515      - simplify mom_vecinv.F (only 1 block for momViscosity).
516    o pkg/mom_common: variable horiz. viscosity in NH code
517      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
518        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
519      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
520        useBiharmonicVisc & useVariableVisc.
521      - fix old bug (already in 1rst implementation of variable horizontal viscosity
522        in calc_gw.F, version 1.27, 2006/06/20):
523        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
524        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
525      - change background horiz viscosity in vertical momentum (gW) to always be
526        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
527        any type of variable viscosity, e.g., viscAh/4Grid)
528      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
529        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
530        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
531        default viscAh,viscA4 is zero).
532    o model/src:
533      - extend length of drC & recip_drC from Nr to Nr+1.
534  o Divided Adjoint (DIVA) with MPI:  o Divided Adjoint (DIVA) with MPI:
535    - 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.
536    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT    - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
