87      - in model/src and pkg/ptracers
88    
89    checkpoint51
90    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
91      - autodiff, ctrl, exf, grdchk, seaice
92      kept separate packages
93      - cost, ecco, obcs
94    o updating verification/internal_wave, verification/lab_sea
95      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
96    
97    checkpoint50i_post
98    o Preparing next differentiable checkpoint and sync
99      of MAIN vs. ecco-branch
100      - 1st step: this one is differentiable
101      - 2nd step: next(! not this) checkpoint will have updated packages
102                  from ecco-branch)
103    
104    checkpoint50h_post
105    o new package "land": provide surface BC for AIM.
106    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
107    o AIM: use true log-P extrapolation for near surface temp (= as in
108        F.Molteni paper) ; update aim.5l_cs output.
109    o New variable in PARM03 for more flexible pickups
110    o somewhat cleaned package initialisation sequence for
111      ctrl/ cost/ ecco/ in packages_... routines
112    
113    checkpoint50g_post
114    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
115      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
116      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
117        made the default because of faster convergence than ADI
118    
119    checkpoint50f_post
120    o exf totally restructured
121      - replaced all exf_set_ routines by one generic exf_set_gen.F
122        and made sure it's still differentiable
123      - split exf_getffields.F into new exf_bulkformulae.F
124      - exf_inscal_/exf_outscal_ suffixes consistent with field names

134     o new fn in pkg/monitor to stop model if solution grows too big
135     o removed lots of single quotes from comments
136    
137    checkpoint50e_post
138    o make KPP work with PTRACERS
139     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
140       nearly a copy of kpp_transport_s
141     - there is no analogue to SurfaceTendencyS, so I have to use
142       gPtr(of the surface layer) instead
143    o add a new platform SunFire+mpi (SunFire 15000) to genmake
144    checkpoint50e_pre
145    
146    checkpoint50d_post
147    o change kpp output from multiple-record state files to single-record state
148      files analogous to write_state.F
149    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
150      analogous to the cg2d-related output.
151    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
152      so that writing to internal file fn (with length 512) fails.
153    checkpoint50d_pre
154    
155    checkpoint50c_post
156    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
157    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
158    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
159    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
160    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
161    
162    checkpoint50c_pre
163    Merging from release1_p13:
164    o bug fix for pkg/seaice dynamic solver
165    o Added SEAICE_initialHEFF to pkg/seaice
166    
167    checkpoint50b_post
168    o store u*,v* in gU,V instead of in guNm1,gvNm1
169    o in order to put the momForcing out of the Adams-Bashforth:
170      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
171      to timestep.F
172    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
173    o re-generate output for highly sensitive test-exp:
174       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
175    
176    checkpoint50b_pre
177    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
178    o corrected CPP option mismatch in exf_Bulk... functions for case
179      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
180    
181    checkpoint50a_post
182    o Bug fix for merging between c50 and KPP.
183      ikey was passed from thermodynamics to kpp_calc via
184      common block rather than being recomputed in kpp_calc,
185      in contradiction with new key itdkey.
186      New key ikppkey created, and tamc.h headers updated.
187    
188    checkpoint50
189    - 2nd step of merge with ecco-branch:
190      merge changes in ecco-branch back into main trunk
191    - bug fix in find_alpha
192    - more storing in gmredi_calc_tensor.F, kpp_routines.F
193    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
194    - merged some sliced AD support routines
195    
196    checkpoint49
197    merged from ecco-branch:
198    o exf:
199      - Enable initialisation of forcing fields to constant
200        (runtime) values.
201      - in exf_getffields.F
202        Reduce i-/j-loop to interior domain, discarding overlaps.
203        That also fixes wrong TAF-key computations for key_1, key_2
204        with bulf formulae.
205      - exf_init.F modify #ifdef for exf_init_evap
206      - exf_getffieldrec.F, ctrl_getrec.F
207        The following INT-usages are not safe:
208          fldsecs  = int(fldsecs/fldperiod)*fldperiod
209          fldcount = int(fldsecs/fldperiod) + 1
210        and were modified.
211    o autodiff: checkpoint_lev...
212      - updated storing for bulk formulae (some arrays were missing)
213      - added state for seaice package
214      - synchronized with main branch
215    o DIVA:
216      Modif.s in
217      - the_main_loop.F
218      - the_model_main.F
219      and added cost_final_restore.F cost_final_store.F
220      o With these changes, it is possible to fully separate
221        the first forward run to compute the cost function (mdthe_main_loop)
222        and adjoint runs over individual DIVA intervals (adthe_main_loop)
223        into separate model executions.
224        This enables better tuning of DIVA to given queue sizes.
225      o Loss of cost function value in consecutive DIVA runs is
226        fixed by storing to 'costfinal' file.
227      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
228        beginning/end of adjoint integration is accounted for.
229      The current changes apply to TAF-1.4.26.
230      TAF has one remaining bug, requiring one manual change
231      (see MITgcm manual).
232    o cal: synchronized between MAIN and ecco-branch
233    
234    checkpoint48i_post
235    o Changes to restore differentiability of code w.r.t. previous tag
236      (mostly adding new routines to make list and replacing
237      pressure by totPhiHyd).
238    o Updated and merged grdchk package
239      - has both ADM and TLM checks
240      - works for single- and multi-proc.
241      - output cleaned
242      - worked successfully for parallel DIVA
243    o genmake:
244      - Adding -platform=SP4
245      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
246    o Modif. for DIVA:
247      ctrl_unpack should not be called in intermediate DIVA interval.
248      (similar thing would apply for active files such as
249      tbar, sbar, psbar, which should not be reinitialised;
250      only relevant for ecco-branch)
251    
252    checkpoint48h_post
253    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
254    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
255    o Added SEAICE_initialHEFF to pkg/seaice
256    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
257    
258    checkpoint48g_post
259    --- EOS:
260    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
261      store total Potential in totPhyHyd for diagnostics & EOS.
262    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
263    --- Pressure/geopotential gradient:
264    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
265    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
266      ( changes results of global_ocean_pressure )
267    o NLFS + z-coord.: add eta*Rho' contribution.
268    o accurate phiHyd when using interface-W at the middle between 2 centers
269     ( changes results of ideal_2D_oce )
270    o includes r* 2nd term in potential gradient.
271    
272    checkpoint48f_post
273    Merging from release1_p12:
274    o Modifications for using pkg/exf with pkg/seaice
275      - improved description of the various forcing configurations
276      - added basic radiation bulk formulae to pkg/exf
277      - units/sign fix for evap computation in exf_getffields.F
278      - updated verification/global_with_exf/results/output.txt
279    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
280      (SBO) core products, including oceanic mass, center-of-mass,
281      angular, and bottom pressure (see pkg/sbo/README.sbo).
282    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
283      to avoid negative values in shallow regions.
284      - updated verification/natl_box/results/output.txt
285      - updated verification/lab_sea/results/output.txt
286    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
287    o Added useSingleCpuIO option (see PARAMS.h).
288    o Updated useSingleCpuIO option in mdsio_writefield.F to
289      work with multi-field files, e.g., for single-file pickup.
290    o pkg/seaice:
291      - bug fix in growth.F: QNET for no shortwave case
292      - added HeffFile for specifying initial sea-ice thickness
293      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
294    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
295      kpp_transport_t.F, forward_step.F, and the_main_loop.F
296    o pkg/seaice:
297      - adjoint-friendly modifications
298      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
299    
300    checkpoint48e_post
301    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
302    o dynamics: change definition of computational domain & adapt mom_fluxform
303      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
304    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
305        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
306        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
307        global_ocean.90x40x15 global_with_exf global_ocean_pressure
308        inverted_barometer solid-body.cs-32x32x1
309      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
310    
311    checkpoint48d_post
312    o in preparation for r*:
313     a) use pre-computed gradient of hydrostatic potential:
314        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
315     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
316        => affects results of glob_oce_pressure (different truncation error)  
317      update output.txt of ideal_2D_oce & global_ocean_pressure
318    
319    checkpoint48d_pre
320    o in preparation for r*:
321      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
322      pass the 2 comp. of the grad. as arguments to momentum S/R.
323      but for the moment, only used if it does not change the results.
324    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
325    
326    checkpoint48c_post
327    Modifications in treatment of initial flux forcing controls
328    to avoid extra storing of flux fields.
329    
330    checkpoint48c_pre
331    o Added tidal_basin_2d experiment (currently 1D!)
332    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
333    
334    checkpoint48b_post
335    o r* coordinate added in #ifdef NONLIN_FRSURF block.
336     (modification to pressure gradient not yet implemented)
337    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
338      (for U & V) that are used for vertical advection of momentum.
339    
340    checkpoint48a_post
341    o In preparation for r*, use temp. array to compute vertical transport
342       in flux-form momentum pkg. => change results of few test-exp.
343      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
344                        lab_sea, natl_box & plume_on_slope
345    
346    checkpoint48
347    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
348    
349    checkpoint47j_post
350    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
351    o moved adexch from forward_step to addummy_in_stepping
352    o added exch in ctrl_map_...
353    o aveFreq.=0. at end of cost_final to avoid overwrite in
354      reverse checkpointing loop
355    o Yet more changes in gmredi:
356      * adgmredi_calc_tensor
357        avoiding all recomputation of gmredi_slope_limit
358      * adgmredi_x/y/rtransport
359        added flag for excessive storing to avoid recomp. of
360        u/v/rtans, dTdx/y/z
361        -> this is not really necessary and very memory-consuming
362      * adgmredi_slope_psi:
363        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
364      * gmredi_slope_limit
365        re-activated full calculation of taperfct for case 'ac02'
366    o updating verification/ adjoints of carbon, global_ocean.90x40x15
367    
368    checkpoint47i_post
369    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
370    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
371      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
372    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
373    o gmredi: fix few bugs.
374    
375    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
376    This will be a good checkpoint to plug into the ecco-branch.
377    o few modif.'s to get latest version adjointed
378      (mainly kick out code in ini_linear_phisurf)
379    o modif's to run adjoint with exactConserv
380    o case GM_BOLUS_ADVEC should be cleaned
381      S/R gmredi_slope_psi should be cleaned
382    o verification/carbon now has exactConserv=.TRUE.
383    
384    checkpoint47g_post
385    o time-average AIM output: becomes independent from statvars time-average
386      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
387    o After TAF bug fix:
388      Tested adjoint of gmredi package.
389      Tests were done with checkpoint47 rather than with latest
390      checkpoint47f_post since the latter is broken for the adjoint
391      verification/carbon/ contains both ADM and TLM gradient checks.
392    Here they are, before they get changed/lost/stolen.
393    Mostly modif.'s to fix numerical sensitivities.
394    Gradient checks OK for
395    - GM_taper_scheme:
396      * clipping
397      * ac02
398      * linear
399      * glw91
400      * dm95
401      * ldd97
402    - GMREDI_OPTIONS:
403      * GM_VISBECK_VARIABLE_K
404      * GM_NON_UNITY_DIAGONAL
405      * GM_EXTRA_DIAGONAL
406      * GM_BOLUS_ADVEC
407    in conjunction with data.gmredi parameters to be checked in
408    in a few minutes under verification/carbon/code/
409
