4      Notes on tags used in MITgcmUV      Notes on tags used in MITgcmUV
5      ==============================      ==============================
6    
7    o pkg/sbo:
8      - update from Katherine Quinn: evaluate mass directly from density and SSH
9        (budget using Finite Volume method) instead of from bottom pressure.
10    o model/src & most packages:
11      - always call {PKG}_READPARMS even if corresponding use{PKG}=F;
12      - in {PKG}_READPARMS, in case use{PKG}=F: add a call to new S/R
13        PACKAGES_UNUSED_MSG to print a weak warning when parameter file
14        "data.{pkg}" exist ; and leave the S/R (return) just after.
15      - more standard LAND pkg interface (land_init_fixed.F, land_check.F).
16        + call LAND_READPARMS from packages_readparms.F
17    o pkg/seaice:
18      - remove code that resets useThSice in S/R seaice_readparms and
19        replace by a warning in S/R seaice_check
20      - remove parameter MULTDIM, replace with nITD and runtime
21        parameter SEAICE_multDim (still hard-wired to nITD if
22        SEAICE_ITD is defined)
23    
24    checkpoint64x (2014/05/24)
25    o verification/lab_sea:
26      - update adjoint and TLM output following changes to pkg/salt_plume
27      - un-do the update after putting back local recip_Cp in few places.
28    o pkg/salt_plume: modifications by An Nguyen:
29      - add capability to do brine rejection (salt-plume) as function of
30        volume+tracers (instead of only salinity tracer).
31      - conserve volume by exchanging volume from each kLev to above to
32        accommodate in-coming brine volume
33      - store surface and klev exchanged fraction + volume in 4 new 3-d arrays
34      - switch KPP surf buoyancy due to brine forcing to 3-d
35        (3 more 3-d arrays, 2 for SPforcing[T,S], 1 for boplume)
36      - add salt_plume_volfrac, salt_plume_apply, salt_plume_tendency_apply_t
37      - unrelatedly, also add ad-hoc capability to vary salt_plume scheme
38        in East/West Arctic.
39    o pkg/sbo:
40      - incorporate modifications from Katherine Quinn to enable the use of sbo
41        pkg in ECCO-v4 set-up ; remove SBO-TimeAve output ; add monitor-like
42        output for future testreport verification (unfinished).
43    o pkg/atm_phys:
44      - change diagnostics (AtPh_Trf & AtPh_Qrf) of DARGAN_BETTSMILLER S/R:
45        skip the reseting of t_ref & q_ref to initial t & q ; this preserve the
46        output of S/R CAPECALCNEW (Parcel temp & q) for diagnostics.
47    o pkg/seaice
48      seaice_calc_ice_strength.F: modify expression to avoid divisions
49        (affects truncation)
50      seaice_do_ridging.F: clean up the insectarium
51      - fix a bug that was compensated by areaScaling (-> remove areaScaling code)
52      - added SEAICEsnowFracRidge to redistributed snow (2nd bug)
53      - set closing/openingRate to zero where no extra iteration is need (3rd bug)
54      - add some debugging information and error messages (warnings)
55    o model/src: modifications relatd to atmosphere p*:
56      - Switch to more accurate p* coordinate slope term (calc_grad_phi_hyd.F)
57      - With p* or Sigma-P, use constant reference Pot.Temp (thetaConst) instead
58        of vertical profile tRef in geopotential background and anomaly.
59      - Acount for true p* correction in theta <-> T conversion in pkg/aim_v23
60        and pkg/atm_phys.
61      - Update FWD output of experiments: aim.5l_cs (x2), fizhi-cs-32x32x40,
62        fizhi-cs-aqualev20, fizhi-gridalt-hs, tutorial_held_suarez_cs, cpl_aim+ocn.
63    o pkg/seaice: fix a bug in seaice_prepare_ridging.F, forgot a sqrt
64    o pkg/ptracers: compute ptracer source/sink due to linear free surface.
65        not used right now, but can be used in BGC packages to fix conservation.
66    o pkg/dic, pkg/gchem: move tracer_meanarea to gchem, so it can be used by
67        other packages too.
68    o pkg/seaice/seaice_calc_ice_strength.F: replace SEAICE_rhoSnow by
69        SEAICE_rhoIce in the Rothrock (1975)-type strength calculations (bug fix)
70    o model/src:
71      - since we have several heat capacity (even in model/src), define "recip_Cp"
72        as local variable (no longer in common block) to avoid any confusion.
73      - add thetaConst in PARAMS.h (to be used with pStar or sigma-P coords).
74    o pkg/exf:
75      - from Jeff Scott: add option (#define EXF_CALC_ATMRHO) to calculate local
76        air density as function of air Temp, Humidity and atm pressure.
77    
78    checkpoint64w (2014/05/02)
79    o verification:
80      - update output_adm.txt files for experiment global_ocean.cs32x15 (seaice &
81        seaice_dynmix) and lab_sea (primary test & noseaicedyn): moving/changing
82        code from seaice_growth.F & seaice_advdiff.F to new ridging routines
83        seaice_reg_ridge.F seaice_do_ridging.F affects AD gradient
84        (down to 8-7 matching digits for global_ocean and 5-6 for lab_sea).
85    o model/src: for atmosphere in p* coords:
86      - store factor rStarFacC**atm_kappa (= pStarFacK) in common block
87      - implement more accurate p* coordinate slope term (in calc_grad_phi_hyd.F),
88        but not yet activated.
89    o pkg/seaice: fix restart problem for ITD with new ice strength parameterisation:
90      - move computation of opnWtrFrac = 1-AREA to before computing ice strength
91      - this changes the results (but not for any verification experiment, because
92        none tests this), but avoids having an extra field in the restart files
93    o pkg/seaice: remove global variable TICE (not needed)
94      - replace by TICES or local variable where necessary (cost_seaice_test,
95        seaice_diagnostics_state)
96      - move copying TICE to TICES from seaice_check_pickup to seaice_read_pickup
97      - use specific read/write routines for reading and writing individual leves
98        of a multilevel field
99    o pkg/ctrl & model/inc:
100      - move additional anomaly fields of control vars (related to options:
101         ALLOW_KAPGM_CONTROL, ALLOW_KAPREDI_CONTROL and ALLOW_BOTTOMDRAG_CONTROL)
102        from DYNVARS.h into new header file: CTRL_FIELDS.h
103    o pkg/seaice: some small modifications to the ridging code
104      - make fw2ObyRidge a global variable and add the freshwater flux to
105        seaice_growth
106      - pass actual thickness from seaice_prepare_ridging, so that it is
107        computed only in one place and compute it in the same way as in
108        seaice_growth
109      - initialise more fields in seaice_do_ridging that where cause floating
110        point exceptions over land
111    o pkg/seaice: preparations for ridging code and first real ridging code
112      - move most of "PART 1" of S/R seaice_growth into a new and separate
113        S/R seaice_reg_ridge that will both regularize the state variable after
114        advection call the actual ridging routine;
115      - requires to make 5 fields global fields: d_HEFFbyNEG,d_HSNWbyNEG,
116        d_AREAbyRLX,d_HEFFbyRLX,saltFluxAdjust;
117      - remove ridging code from seaice_advdiff
118      - clean up remaining part 1 of seaice_growth in an attempt to make it
119        more readable (this is probably subjective)
120      - call seaice_itd_redist once in the initialisation phase to have the initial
121        conditions in the correct category
122      - finally: add new ridging routine for ITD code
123    
124    checkpoint64v (2014/04/11)
125    o pkg/ecco:
126      - add runtime parameters mdt[start,end]date[1,2]
127      - rename variable "tpmean" as "mdt" and "topexmeanfile" as "mdtdatfile"
128    o pkg/seaice:
129      - make deltaC a global variable, so that it can be used in ridging code
130      - first step towards ridging: introduce new routines that compute
131        ice strength based on ridging parameters
132      - add diagnostic for HSNOWITD
133      - add opnWtrFrac as a global variable (required for ridging scheme)
134    o pkg/salt_plume + pkg/seaice/seaice_growth.F
135      - add SALT_PLUME_IN_LEADS flag to activate pkg/salt_plume only when ice
136        AREA exceeds a threshold (code contributed by I.Fenty in 2011)
137    o verification/hs94.1x64x5:
138      - leave ALLOW_AUTODIFF_TAMC undefined in code_oad/AUTODIFF_OPTIONS.h
139      - do not use ECCO_CPPOPTIONS.h anymore for TAF & OpenAD Adjoint tests.
140    o autodiff:
141      - Start to include explicitly AUTODIFF_OPTIONS.h, COST_OPTIONS.h,
142        and CTRL_OPTIONS.h in src files (to enable to skip the ECCO_CPPOPTIONS.h)
143        For now, only in pkgs used in verification/hs94.1x64x5.
144      - Replace ALLOW_AUTODIFF_TAMC by ALLOW_AUTODIFF (except for tape/storage
145        which are specific to TAF/TAMC).
146      - Replace ALLOW_AUTODIFF_OPENAD by ALLOW_OPENAD:
147        since ALLOW_OPENAD is defined in PACKAGES_CONFIG.h (any time pkg/openad
148        is compiled), this simplifies/reduces which *_OPTIONS.h file to include.
149      - OpenAD: change Makefile to generate the appropriate AD_CONFIG.h when
150        building mitgcmuv_ad (make adAll).
151    o pkg/ecco:
152      - cost_gencost_seaicev4.F:
153         reformulate proxy cost as function of sst and local param SEAICE_freeze
154         change cost names from siv4-[sst,vol] to siv4-[deconc,exconc]
155      - add stop statement if old names siv4-[sst,vol] are used
156      - add snapshots + cost reports for atmospheric longwave
157      - remove factor 0.1 in front of wtau[u,v]
158      - replace never used flag ALLOW_TMI_COST_CONTRIBUTION with
159         ALLOW_TMI_SST_COST_CONTRIBUTION
160    o pkg/atm_phys:
161      - add some diagnostics for Short-wave and for convection S/R.
162    o pkg/seaice/seaice_growth:
163      - fix a bug in the lateral melt parameterization for SEAICE_ITD
164        in seaice_growth; tempFrz needs to be computed inside the i/j-loop
165      - rearrange loop order for better vector code in the same code block
166      - rewrite the floeDiameter formula to have fewer divisions
167      -  (miraculously) none of this changes the results of seaice_itd
168    o pkg/smooth:
169      - move param smooth2Ddiffnbt to pkg/ecco
170    o pkg/salt_plume:
171      - salt_plume_frac.F:
172         clean up local param names
173         reformulate (1-frac) to frac; original 1-frac was based on swfrac code
174    o pkg/rw:
175      - add RS version of S/R READ_MFLDS_LEV.
176    o pkg/streamice:
177      - fix the restart test by writing/reading pickup_streamice files.
178    o pkg/seaice:
179      - refine checks for jfnk-related parameters
180      - comment out if statement with SEAICEuseIMEX parameter as long as there
181        is no IMEX code to avoid confusion and surprises
182    
183    checkpoint64u (2014/03/07)
184    o verification/MLAdjust:
185      - rename secondary test suffix:
186         1.leith  -> A4FlxF  + switch to flux-form & add side-drag
187         0.leithD -> AhFlxF  + switch to flux-form
188         0.smag   -> AhVrDv  (use Vorticity-Div. visc form) + add side-drag
189         0.leith  -> AhStTn  (use Strain-Tension visc form) + add side-drag
190    o pkg/mom_vecinv:
191      - remove unused arguments from S/R MOM_VI_HDISSIP & MOM_HDISSIP (as it used
192        to be before mom_calc_visc.F)
193      - skip the call to MOM_CALC_TENSION & MOM_CALC_STRAIN if not needed.
194      - add 2nd copy of vort3 & strain that knows about lateral BC (free/no slip):
195        this is simpler for the adjoint and for diagnostics.
196    o model/src + pkg/momentum:
197      - add input files for  2-D additional Western and Southern cell-edge wall
198         (e.g., to add "thin-wall" where it is =1).
199      - fix sideDrag option for thin-walls with Non-Lin Free-Surf
200        using 2nd hFacZ that is computed from initial (fix domain) hFac
201      - known limitations of thin wall implementation: not yet coded for sigma
202        coords; not working with CD-scheme neither.
203    o pkg/seaice:
204      - rename recently introduced parameters from (wrong name) AB to
205        BDF (backward difference time discretisation)
206      - retire runtime parameters SEAICEuseAB2, SEAICE_abEps
207    o tools/adjoint_options:
208      - remove setting of "OPENAD=true" (now set by command line "genmake2 -oad")
209    
210    checkpoint64t (2014/02/01)
211    o pkg/ecco
212      - add compile flag ALLOW_GENCOST_TIMEVARY_WEIGHT in ECCO_OPTIONS.h and
213        runtime logical flag gencost_timevaryweight to read daily sea-ice sigma
214      - replace hard-coded record number and period which only work for monthly
215        with read-in runtime param that works for other periods (month,day,year)
216    o pkg/thsice
217      - corrected store directive fixes thsice adjoint gradient checks
218    o genmake2 & testreport:
219      - add genmake2 option "-oad" to generate a Makefile for OpenAD built and
220        in this case, use tools/adjoint_options/adjoint_oad as default AD optfile.
221        Update testreport accordingly. No need to set "export OPENAD=true"
222        in adjoint_options/adjoint_oad anymore (will be removed later).
223    o pkg/shelfice:
224      - put T & S shelfice forcing into model surfaceForcing_T,_S (for now,
225        only if SHELFICEboundaryLayer=F); Change model/src/external_forcing.F
226        so that surface forcing applies to k=kSurf if using pkg/shelfice.
227    o pkg/ctrl, pkg/grdchk, pkg/ecco:
228      - Changes to make GENARR more modular (i.e. invisible if not used)
229    o model/src/temp_integrate.F and salt_integrate.F
230      - re-include store directives that were removed on Dec 27th.
231    o model/src/external_forcing_surf.F
232      - add storage directives for EmPmR and PmEpR to avoid recomputation of
233        seaice_model in the adjoint that is problematic when seaice_model is
234        turned off in the adjoint. The resolved issue dated back to July when
235        EXTERNAL_FORCING_SURF call was moved.
236        Update global_ocean.cs32x15/*/output_adm.seaice_dynmix.txt accordingly.
237    o pkg/exf/exf_check.F
238      - fix a small bug again (originally found by Wentao Liu, now found again)
239      - streamline error output
240    o pkg/streamice and aim_v23:
241      - replace a few "_EXCH_XY_RL (" with "_EXCH_XY_RL(", so that
242        Apple's /usr/bin/cpp knows what to do:
243        Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
244        Target: x86_64-apple-darwin13.0.0
245    
246    checkpoint64s (2014/01/05)
247    o tools/adjoint_options:
248      - switch to fastopt.net TAF server (instead of default fastopt.de) for
249        AD optfiles adjoint_diva & adjoint_f95 (similar to adjoint_default).
250    o model/src:
251      - remove some unnecessary TAF storage directives in forward_step.F and
252        in dynamics.F (note: not always removed by TAF, e.g., double storage
253        of kappaRU,kappaRV in former version of dynamics.F).
254    o model/src & pkg/ptracers:
255      - call directly GAD_IMPLICIT_R & IMPLDIFF + DWNSLP_APPLY from temp_integrate.F
256        salt_integrate.F and ptracers_integrate.F (instead of from thermodynamics.F)
257        and remove ptracers_dwnslp_apply.F & ptracers_implicit.F
258      - call MATRIX_STORE_TENDENCY_EXP for each tracer (in ptracers_integrate.F)
259      - add fZon & fMer as output argument of S/R GAD_CALC_RHS.
260      - update TAF AD-output of experiments global_ocean.90x40x15 (13 for AD-grad).
261    o useSingleCpuInput separates single-CPU input from single-CPU output;
262        for now only implemented for in exf_interp_read.F
263    o verification/advect_xy:
264      - fix missing EXCH call in local version of ini_salt.F and update output.
265    o momentum diagnostics:
266      - fix which deltaT is used in Total-Tendency diagnostics.
267      - fix typo in diagnostics for momentum tendency from AB.
268    o pkg/seaice/seaice_lsr.F: fix an initialisation bug for the
269        SEAICE_VECTORIZE_LSR_ZEBRA option that lead to NaNs on a NEC-SX8
270    
271    checkpoint64r (2013/12/08)
272    o verification/*/results:
273      - Update reference output of experiments that were passing with just 13 digits
274         (make it easier to detect future changes in results)
275    o model/src & pkg/ptracers:
276      - move calls to GAD_ADVECTION (Multi-Dim advection) from thermodynamics.F to
277        inside temp_integrate.F and salt_integrate.F and from ptracers_advection.F
278        to inside ptracers_integrate.F ; remove ptracers_advection.F
279    o coupling interface pkgs:
280        [atm_compon_interf, ocn_compon_interf & atm_ocn_coupler]
281      - change the config check to test the agreement of Ocean Depth
282        with ATM land/sea mask (instead of ATM orography);
283      - send to coupler the number of coupler time-steps to do for this run:
284        this allows to check for consistency and don't need anymore to be
285        specified in parameter file "data";
286      in coupler:
287      - check consistency of RunOff map versus Ocean Depth and ATM land/sea mask.
288      - improve report to log-file of config setting (pass log-file unit to few S/R)
289    o pkg/compon_communic:
290      - add coupling send/receive for non-tiled integer vector;
291      - add S/R to check and stop if any proc has an error (similar to
292        eesupp/src/stop_if_error.F but single thread and across Comm_World).
293    o pkg/exch2:
294      - in exch2*_get_rx[1,2]: use new list "W2_tileIndex" to replace search
295        through list of all tiles my proc owns.
296    o model/src:
297      - AUTODIFF only: in calc_adv_flow.F, recompute rTransKp (instead of copying
298        from rTrans) to simplify dependencies (no need to store rTrans anymore in
299        calling S/R); this affects AD results at machine truncation level:
300        update AD-output (TAF) of experiments: 1D_ocean_ice_column,
301        bottom_ctrl_5x5 & obcs_ctrl (12 digits for AD grad, same FWD grad).
302    o tools/build_options:
303      - simplify Warnings options (-ieee & -devel cases) in linux_amd64_gfortran
304    o coupling interface pkgs:
305        [compon_communic, atm_compon_interf & ocn_compon_interf]
306      - move declaration of local array "ibuf" out of header file "CPLR_SIG.h"
307        to each S/R that needs it; remove un-used variables.
308      - change component tile registration (cpl_register.F in both compon_interf
309        and mitcomponent_tile_register.F) to pass the full list of tiles
310        information (including bi,bj) in 1 vector (instead of in a bi,bj matrix).
311      - with pkg/exch2: adopt the same convention used for I/O to define mapping
312        towards coupler global array (unless W2_useE2ioLayOut=F):
313         a) can now use different tiling between atm & ocn comp.
314         b) no needs to modify the run-Off map when changing tiling (was needed
315            even if using the same tiling between atm & ocn).
316         c) will allow to run with blank-tiles in 1 component (e.g., for ocean
317            full land tiles); not yet tested.
318      - check for valid mapping from comp. tile to coupler global array
319      - improve report of tile registration results to log file.
320    o pkg/exch2:
321      - in eesupp/src/eeboot.F: move call to W2_EEBOOT before Coupler
322        tile-registration (CPL_REGISTER);
323      - activate (un-comment) definition and setting of "W2_tileIndex" list to
324        store the local bi,bj indices of each tile;
325      - also print bi,bj in local report to log file;
326      - fix pkg/debug/debug_cs_corner_uv.F for the case nSy > 1 (left from
327        Jun 2009 modif of pkg/exch2).
328    o testing on baudelaire:
329      - run 2 tests at a time: no significant slow down (since enough cpu) and
330        get the full set of test done earlier
331      - switch the ifort test to "-devel" ; run the OpenAD test everyday.
332    o model/src/thermodynamics.F and routines called from it:
333      - pkg/gmredi: gmredi_residual_flow.F (replacing gmredi_calc_uvflow.F &
334        gmredi_calc_wflow.F) to update eulerian velocity (input) into residual
335        velocity (outp) by adding bolus velocity.
336      - model/src: calc_adv_flow.F (replacing calc_common_factors.F) to compute
337        mass transport from velocity + lateral grid cell area
338      - rename calc_gt.F to temp_integrate.F (includes call to TIMESTEP_TRACER)
339      - rename calc_gs.F to salt_integrate.F (includes call to TIMESTEP_TRACER)
340     in thermodynamics.F
341      - remove k from thermodynamics.F and move it to temp_integrate.F
342        salt_integrate.F and ptracers_integrate.F (now done inside the tracer
343        loop).
344      - compute locally (in thermodynamics.F) 3-D velocity field that is used to
345        advect tracers; pass it as argument to GAD_ADVECTION, GAD_SOM_ADVECT,
346        PTRACERS_ADVECTION, TEMP_INTEGRATE, SALT_INTEGRATE, PTRACERS_INTEGRATE,
347        GAD_IMPLICIT_R and PTRACERS_IMPLICIT
348      - update AD-output (TAF & OAD) of experiments: 1D_ocean_ice_column,
349        global_ocean.90x40x15, tutorial_global_oce_biogeo and
350        tutorial_tracer_adjsens (+ TLM output).
351    o tools/OAD_support and (verification/*/) code_oad:
352      - OAD_support/cb2mGetModules.csh: add PACKAGES_CONFIG.h in header file to
353        module conversion ; remove unneeded CPP_EEOPTIONS.h.
354      - code_oad/CPP_OPTIONS.h: remove PACKAGES_CONFIG.h and use a more standard
355        version (closer to model/inc/CPP_OPTIONS.h).
356    o model/src:
357      - remove parameter "useOldFreezing" from PARAMS.h and push it to the
358        retired list of parameters (routine FREEZE has been replace by surface
359        freezing (10.yrs ago) and by pkg/frazil (interior freezing).
360    o pkg/gmredi:
361      - add option (GM_CALC_TRANSP_FROM_VEL) to compute transport directly from
362        velocity (same scheme but affects machine truncation) for GM_AdvForm.
363      - update output of FWD experiments: front_relax.bvp,
364        global_ocean.90x40x15.dwnslp, global_ocean.cs32x15 and ideal_2D_oce.
365    
366    checkpoint64q (2013/11/17)
367    o verification:
368      - generate new output on baudelaire (gfortran, -ieee) for OpenAD experiments
369        tutorial_global_oce_biogeo and global_ocean.90x40x15.
370      - generate new output (growth & melt) for seaice_itd experiment after
371        updating the input pickup_seaice files (previously wrong).
372    o pkg/cost:
373      - define a "final cost function" for each tile, and use GLOBAL_SUM_TILE_RL
374        (instead of _GLOBAL_SUM_RL) to get the final cost from all procs & threads:
375        o this fixes global-sum value if multi-threads (since GLOBAL_SUM_RL
376          cannot be applied to var in common block).
377        o allows to get results independent of tile-per-proc setting (if using
378          slower GLOBAL_SUM_SEND_RECV option).
379      - update accordingly: seaice_cost_final.F, shelfice_cost_final.F,
380        thsice_cost_final.F and ecco_cost_final.F (this one affects lab_sea
381        forward gradients: update output).
382      - update */code_oad/externalDummies.F by adding dummy GLOBAL_SUM_TILE_RL
383        S/R and, for most exp., also comment out GLOBAL_SUM_R8.
384    o pkg/mom_common:
385      - move to pkg/mom_common and model/src (previously in tutorial_deep_convection
386        code) 2nd version of isotropic 3-D Smagorinsky code interface: strain and
387        viscosity are locally declared in dynmics.F and pass as argument to CALC_GW;
388        ensure that all field value that are used are set.
389    o tutorial_deep_convection (smag3d):
390      - add missing scaling in mom_calc_smag_3d.F;
391      - set smag3D_coeff in input.smag3d such that results do not change.
392    o pkg/dic:
393      - change dic_cost.F to compute cost on each tile first and then apply
394        GLOBAL_SUM_TILE_RL: this affects forward gradient of AD experiments
395        tutorial_dic_adjoffline & tutorial_global_oce_biogeo; update output.
396      - remove kLev argument and use GLOBAL_SUM_TILE_RL in tracer_meanarea.
397    o eesupp/src & pkg/mdsio:
398      - remove gather/scatter_vector.F (from eesupp) and mdsio_read/writevector.F
399        (from pkg/mdsio) since they are no longer used for tape IO.
400      - move simple C subroutine "setdir.c" from pkg/compon_communic to eesupp/src
401        (+ keep a copy in pkg/atm_ocn_coupler).
402    o verification/isomip:
403      - split domain in 8 squared tiles (instead of just 2) for FWD, AD & OAD tests.
404    o tools/build_options:
405      - optfile linux_amd64_ifort11, fast (no ieee) case:
406        to get a working restart for all experiments, add "-fp-model source"
407        to FOPTIM (also remove "-opt-streaming-stores auto" <- this is the default).
408    
409    checkpoint64p (2013/10/20)
410    o pkg/autodiff:
411      - adread_adwrite.F: when type and length do not match ALLOW_AUTODIFF_WHTAPEIO
412        criteria, return to simple (default) tape IO format.
413    o pkg/mdsio (+ eesupp/src):
414      - rewrite/simplify tape-IO S/R (new S/R MDS_READ/WRITE_TAPE replace
415        previous MDSREAD/WRITEVECTOR) with 2 array argument from each type (R4/R8);
416      - fix globalFile and singleCpuIO options using simpler global mapping.
417      - new pairs of scatter/gather vector S/R (one for each type, generated from
418        template) corresponding to simpler global mapping.
419      - adread_write.F: switch to new S/R (but leave old calls commented) and write
420        to globalFile when parameter globalFiles is set to True.
421      - switch on useSingleCpuIO in AD experiments: global_ocean.90x40x15 & isomip.
422    o pkg/autodiff:
423      - adread_adwrite.F: add a hack for RS arrays (when RS=real*4);
424        with ALLOW_AUTODIFF_WHTAPEIO defined, since corresponding (real*4) is
425        missing, just add a STOP if array type do not match.
426    o pkg/exf:
427      - to allow to use seaice-fraction from pkg/exf in other pkgs than pkg/seaice:
428         rename CPP option EXF_ALLOW_SEAICE_RELAX to EXF_SEAICE_FRACTION
429         and rename array obsSIce to exf_iceFraction.
430    o tutorial_deep_convection:
431      - add 1rst version of isotropic 3-D Smagorinsky code (from Louis-Philippe),
432        for now all in this exp. code dir.
433      - add secondary test using Smag-3D viscosity (keep very low backgroud visc for
434        testing) and flux-limter advection scheme for Temp. (no explicit diffusion).
435    o eesupp/src:
436      - added SINGLE_DISK_IO option because reading of parameter files on
437        very large number of processors did not work with existing set-up
438    
439    checkpoint64o (2013/09/25)
440    o pkg/atm_phys & atm_compon_interf:
441      - allows for coupling of gray-atmosphere (atm_phys) with ocean.
442    o tools/build_options:
443      - switch from "-fPIC" to "-mcmodel=medium" in optfiles: linux_amd64_gfortran
444        & linux_amd64_ifort11 and in linux_amd64_g77 & linux_amd64_open64 also
445        remove CPP setting (was identical to genmake2 default).
446    o pkg/gmredi & model/src: Some updating and work done on the residual model.
447      - created new file model/src/calc_eddy_stress.F to calculate the eddy stress.
448      - fixed up the calculation of the eddy stress and how it is added to the
449        external forcing via taueddy_external_forcing.F
450      - at the moment, it is very experimental and only works with the variable eddy
451        diffusivity calculated in gmredi_k3d.F
452    o pkg/seaice/seaice_check.F: add a check to catch the case of specifying
453        lw/swfluxfile instead of lw/swdownfile in data.exf together with pkg/seaice
454    o testreport (& tools/do_tst_2+2):
455      - for MPI test, set default COMMAND to 'mpirun -v -np TR_NPROC ./{executable}'
456    o tools/build_options: linux_amd64_gfortran & linux_amd64_ifort11:
457      - remove CPP='cpp -traditional -P' (this is genmake2 default)
458      - add switch (for big setups) to use 'medium' memory-model (but leave it
459        commented out for now). Note: needed with FC 19 to compile big setups.
460    o pkg/atm_compon_interf:
461      - regroup per field origin (model & pkgs) the coupling storage routines
462         (which accumalate in time each coupling field)
463      - move bi,bj loops inside atm_store_my_data.F and store also wind-stress;
464        update accordingly + simplify aim_do_physics.F
465    
466    checkpoint64n (2013/08/26)
467    o pkg/bbl:
468      - update formulation to reduce dispersion of tracer properties in bbl
469      - replaced horizontal and vertical transport parameters with velocities
470      - changes results for verification/global_with_exf.yearly
471    o verification/halfpipe_streamice:
472      - change to matrix construction; update both Fwd & AD output.
473    o verification/tutorial_tracer_adjsens:
474      - OpenAD test: switch to vector-invariant momentum since fluxform with
475        rStar causes problems with OpenAD; update output.
476    o tools:
477      - genmake2: define a common prefix for all temp-file names ; move them
478        to local /tmp disk (but would be easy to move them back);
479      - xmakedepend: apply the same switch for temp-files.
480    o pkg/offline:
481      - changes for use with rStar (NLFS): assume that we continue to provide
482        UVELMASS/hFacW_ini & VVELMASS/hFacS_ini (hFacWi,S_ini as written in grid
483        output files) and apply r* scaling at each time-step (function of the time
484        varying Eta field); use normal pickup files (needed for restart with NLFS).
485    o adjoint with OpenAD:
486      - move OpenAD-specific files from verification/OpenAD/code_oad_all to a new
487        package openad.  This package has to be compiled for all runs with OpenAD
488        instead of specifying code_oad_all as a modification directory.
489      - link the fortran templates from tools/OAD_support to the build directory
490        for preprocessing to avoid conflicts between different setups compiled
491        simultaneously and simplify cleanup.
492    o pkg/exf:
493      - in exf_getforcing.F: comment out most of the EXCH calls (fields used by
494        main model or other pkgs are exchanged in EXF_MAPFIELDS).
495    o model/src:
496      - do_stagger_fields_exchanges.F: skip EXCH calls when using pkg/offline
497        (similar to do_fields_blocking_exchanges.F).
498    o tools/genmake2:
499      - remove TAF output src code just before calling staf (when not doing a fresh
500        built, will stop if things go wrong with staf).
501      - fix target "adobj" (left from TAF version-2 transition)
502    o pkg/diagnostics:
503      - add a parameter to track the status of pkg/diagnostics activation;
504        this replace/extend the use of logical param "settingDiags" (to check
505        when adding diag to the list) to also check any DIAGNOSTICS_[]FILL* call.
506        New S/R to print error message and stop when pkgStatus is not right.
507      - to try: add a warning when "data.diagnostics" exist but useDiagnostics=F.
508    
509    checkpoint64m (2013/08/13)
510    o model/inc:
511      - move FCORI_MACROS.h from PARAMS(_MACROS).h to GRID_MACROS.h (left from
512        8 yrs ago modif when Coriolis arrays were moved from PARAMS.h to GRID.h)
513    o pkg/kpp & aim_v23:
514      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
515    o pkg/seaice:
516      - restore (last time on 2011/12/24) ability to compile pkg/seaice with
517        undefined pkg/exf ALLOW_ATM_TEMP or ALLOW_RUNOFF CPP-options.
518      - only call DIAGNOSTICS_FILL when useDiagnostics=TRUE.
519    o eesupp/src:
520      - fix check for overlap-size argument (myOLn.GT.MAX_OLY_EXCH)
521        in exch1_rx[_ad].template (thanks to Francois Lefeuvre report).
522    o switch to TAF version-2:
523      - add flow directives to "freeze" naming convention for ad-routines that
524        are used in I/O routines of adjoint state and associated common blocks
525        that are used in adcommon.h (backward compatible with version-1)
526      - update all ad-optfiles (in tools/adjoint_options + few local to some
527        verification exp) to switch to latest TAF version (currently 2.5.5);
528        merge "*_mpi" adoptfiles into the corresponding non-mpi (but commented
529        out except for diva).
530      - the major change with TAF version-2 is that both the differentiated
531        routines and the forward routines (new) are returned as part of the TAF
532        output source code. Update genmake2 accordingly.
533      - new output for AD experiment tutorial_global_oce_biogeo (better AD gradient
534        with version-2 when compared to TLM or FWD gradient); other experiments
535        output show minor changes (machine truncation level); update the few AD &
536        TLM output with 12 matching digits only (some prior to version-2 switch).
537    
538    checkpoint64l (2013/08/05)
539    o model/src:
540      - in dynamics.F, skip the call to CALC_VISCOSITY if momViscosity=F
541      - main_do_loop.F: no longer includes additional (AUTODIFF) header files
542        when using TAF but only if using OpenAD.
543    o pkg/mom_common+fluxform+vecinv:
544      - always set horiz. viscosity arrays to background value before calling
545        MOM_CALC_VISC (in MOM_FLUXFORM & MOM_VECINV) and call S/R MOM_CALC_VISC
546        only when using variable horiz. viscosity (useVariableVisc=T);
547      - simplify mom_vecinv.F (only 1 block for momViscosity).
548    o pkg/mom_common: variable horiz. viscosity in NH code
549      - move horiz-viscosity 3-D arrays viscAh_W & viscA4_W (used in calc_gw.F)
550        from model/inc/NH_VARS.h to pkg/mom_common/MOM_VISC.h
551      - store in common block (in MOM_VISC.h) logical parameters: useHarmonicVisc,
552        useBiharmonicVisc & useVariableVisc.
553      - fix old bug (already in 1rst implementation of variable horizontal viscosity
554        in calc_gw.F, version 1.27, 2006/06/20):
555        horizontal bi-harmonic viscosity in gW was missing when wiscA4W=0
556        even if variable bi-harmonic viscosity (e.g., viscA4Grid) was non-zero.
557      - change background horiz viscosity in vertical momentum (gW) to always be
558        viscAhW,viscA4W (instead of switching to viscAhD, viscA4D when using
559        any type of variable viscosity, e.g., viscAh/4Grid)
560      - change default value of viscAhW,viscA4W to viscAhD,viscA4D (instead of
561        viscAh,viscA4) which default to viscAh,viscA4 :  this avoid missing
562        horiz. viscosity in W eq when just setting viscAhD/Z,viscA4D/Z (since
563        default viscAh,viscA4 is zero).
564    o model/src:
565      - extend length of drC & recip_drC from Nr to Nr+1.
566    o Divided Adjoint (DIVA) with MPI:
567      - genmake2: do not create local ./mpi_headers dir when no file to copy into.
568      - remove option ALLOW_DIVIDED_ADJOINT_MPI (replaced by ALLOW_DIVIDED_ADJOINT
569        and ALLOW_USE_MPI) from model/src code and from ECCO_CPPOPTIONS.h.
570    
571    checkpoint64k (2013/07/23)
572    o tools/OAD_support:
573      - avoid the need for file "oadtempflile" in insertTemplateDir.bash
574        and remove it from genmake2.
575    o tools/build_options:
576      - remove MPI_HEADER_FILES_INC setting (no longer used) and comment out
577        MPI_HEADER_FILES list (let genmake2 find the missing headers)
578    o verification/halfpipe_streamice:
579      - change to driving stress formulation; update both Fwd & AD output.
580    o tools/genmake2 and Divided Adjoint with MPI:
581      - remove default setting of MPIINCLUDEDIR from $MPIHOME (always been broken);
582      - only create local ./mpi_headers dir if using MPI and MPIINCLUDEDIR is set;
583      - add new variable (LOCAL_MPI_HEADERS, replace MPI_HEADER_FILES_INC) in
584        Makefile, which is set by genmake2, and check which mpi-headers are needed.
585        Note: need to update adjoint_options/adjoint_diva_mpi accordingly.
586      - update target "CLEAN" (to also remove ./mpi_headers/ dir).
587    o testreport:
588      - changes for Divided Adjoint Run: when file "run_ADM_DIVA" is present,
589        perform additional runs (number of additional runs is "add_DIVA_runs" taken
590        from file run_ADM_DIVA ; should match "nchklev_3" in file "code_ad/tamc.h").
591    o verification/lab_sea (AD test):
592      - change to test Divided Adjoint Run in this set-up (both standard AD test
593        and 2 secondary AD test: noseaice + noseaicedyn); drop the evp AD test.
594    o pkg atm_ & ocn_compon_interf:
595      - remove cpl_earlyExpImpCall=F option (was mainly a hack added for the old
596        staggerTimeStep implementation) and disable (retired) corresponding
597        parameter.
598    o pkg/offline:
599      - comment out unused field-array: ICEM, ConvectCount, hflx[01], icem[01];
600      - add S/R OFFLINE_CHECK to print offline parameter summary
601        and stop if loading a file that is not used;
602      - enable to calculate GMRedi tensor, KPP mixing and convective index
603        when the corresponding file(s) is/are not specified (but pkg is used).
604      - comment out resetting of monitorFreq (to endTime) since it still useful
605        for monitoring CFL numbers and checking offline fields.
606    o OpenAD:
607      - do not define OAD_DEBUG (in tools/adjoint_options/adjoint_oad) to get
608        smaller standard output) and generate new (smaller) output (on baudelaire
609        using gfortran with -ieee) for exp. tutorial_tracer_adjsens
610    o model/src:
611      - call EXTERNAL_FORCING_SURF outside bi,bj loops (in do_oceanic_phys.F),
612        (where external_forcing_adjust was called) and change list of arguments;
613      - merge external_forcing_adjust.F into external_forcing_surf.F
614      - put surface relaxation of SST & SSS in new S/R (forcing_surf_relax.F)
615        which also contains balancing surface relaxation (ALLOW_BALANCE_RELAX,
616        previously in file "balance_relax.F", now removed); remove corresponding
617        arrays in FFIELDS.h.
618      - EXTERNAL_FORCING_SURF is now called when using pkg/offline; implement
619        a hack for getting back surfaceForcingS (loaded from file) when using
620        ALLOW_OLD_VIRTUALFLUX (pkg/dic, in DIC_OPTIONS.h) in offline set-up.
621      - update output of AD test experiment global_ocean.cs32x15.seaice_dynmix
622        (was getting only 11 digits for AD-grad, due to different truncation
623         error in AD code).
624    
625    checkpoint64j (2013/07/04)
626    o pkg/offline:
627      - to enable the use of other features with pkg offline (e.g., obcs),
628        also call S/R DO_OCEANIC_PHYS in offline run - more modifs to come.
629      - comment out "allowFreezing" (now active) in 2 offline testing exp.
630    o pkg/exf ALLOW_RUNOFTEMP
631      - fix sign and make compatible with temp_EvPrRn .NE. UNSET_RL
632      - ahdded RUNOFTEMP test to verification/global_ocean.cs32x15/input.seaice
633      - changes verification/global_ocean.cs32x15/results/output.seaice.txt
634    o pkg/atm_phys:
635      - allows to add some damping on uVel,vVel (strength only function of k).
636    o verification, ad-tests:
637      - reduce length of the simulation for AD test: global_ocean.cs32x15.seaice,
638        global_ocean_ebm and offline_exf_seaice.thsice.
639    o verification/halfpipe_streamice:
640      - found a bug in s/r pkg/streamice/streamice_advect_thickness which caused
641        flux input boundary conditions to be ignored; a fix for this bug changed
642        verification results for forward test.
643      - add adjoint test.
644    o pkg/ptracers:
645      - allow to restart without SOM pickup (resetting SOM to zero).
646    o pkg/gmredi:
647      - New parameterisation for the calculation of K and (GM_PsiX,GM_PsiY) added.
648      - It uses mixing length theory and suppression by steering level effects to
649        calculate a diffusivity used in the Redi tensor (see Bates et al., submitted
650        to JPO, for more details).
651      - It also uses the diffusivity to calculate an eddy induced streamfunction
652        based on a PV closure (rather than a buoyancy closure as in GM).
653      - New files added to pkg/gmredi:
654        gmredi_k3d.F calculates the diffusivity for the Redi tensor and the eddy
655          induced overturning streamfunction (called from gmredi_calc_tensor)
656        gmredi_calc_eigs.F calculates the eigenvalues and eigenvectors required
657          for use in gmredi_k3d
658        gmredi_calc_urms.F calculates the the rms eddy velocity used to calculate
659          the eddy diffusivity
