This alone reduces the cpu + time spent in this routine by more than a factor of 3 on an NEC-SX8 + - step 2: replace search algorithm by a bisection algorithm found in + Press et al. Numerical Recipes in Fortran. This algorithm can be + vectorized and finds the correct bin in approx. log2(Nlayers) steps. + For now, use this algorithm only for TARGET_NEC_SX defined. + - moved the search algorithm into a separate subroutine, that is kept + within the same file for automatic inlining. + - modified catching potential errors +o pkg/ecco: + - add compile switches ALLOW_SHALLOW_ALTIMETRY and ALLOW_HIGHLAT_ALTIMETRY. +o model/src, pkg/autodiff, pkg/ctrl, pkg/grdchk : + - modifications for ALLOW_GENTIM2D_CONTROL + -- forward_step.F, the_main_loop.F : pass options and arrays for adjoint tapes. + -- load_fields_driver.F : add call to CTRL_MAP_GENTIM2D( myTime, myIter, myThid ) + -- add xx_gentim2d0/1 in ctrl_ad_check_lev1_dir.h checkpoint_lev1_directives.h etc + -- use ctrl_swapffields.F (new) instead of exf_SwapFFields.F in ctrl_get_gen.F +o model/src: + - account for moist thermodynamics in (dry) potential temperature equation;

+ - update diagnostics for Intermediate State thsice diagnostics: now filled + just before advection (instead of just after advection in old sequence); + - update output of experiment offline_exf_seaice (standard test);

+ - use standard pkg/mdsio routines to read & write CO2 pickup file; + - in-line S/R AIM_AIM2DYN_EXCHANGES in aim_do_physics.F; + - Implement new sequence of calls for seaice advection (with thsice and + seaice diffusion): do ice advection after ice-Thermodynamic (previously + was done before); change aim_do_physics.F (split the bi,bj loops block); + - use same CPP option (OLD_THSICE_CALL_SEQUENCE) to recover old sequence; +o pkg/thsice: + - add a missing EXCH of sIceLoad in thsice_main.F (ocean set-up) for the case + where just seaice diffusion is used without seaice-dynamics. + +checkpoint64c (2013/01/18) +o pkg/seaice: + - add a parameter JFNKres_tFac that can replace JFNKres_t + (= JFNKres_tFac*JFNKresidual before JFNK solver) + - add a line search option to the JFNK solver + - move update of u/vIce and computation of initial residual into a separate + routine (same file); makes the code a little easier to read (?) + - the line search requires computation of the residual and for some reason + I cannot do the update of u/vIce at the beginning of the Newton loop + without changing the results, so we move computation of the new residual + also to the end of the Newton loop, even without the line search +o pkg/mdsio: + - write missing value (corresponding to undefined array value) to meta files; + skip this if missing value is one (UNSET_RL would be a better value for the + case of undefined missing value but it's current the default missing-value); + Also update mdsio_read_meta.F (reading timeInterval & missing-value). +o pkg/exf & thsice: + - for diagnostics purpose, fill-up and update Qsw array (+ fill the + diagnostics) even when SHORTWAVE_HEATING is #undef; +o verification/cfc_example: + - turn on pkg/layers with pkg/diagnostics (to test pkg/layers and to + illustrate how to use it). +o verification/offline_exf_seaice: + in input: add SEAICErestoreUnderIce=.TRUE., and reduce size of forcing + files to only one time-record. + in input.thermo: narrow the 2 bands of low initial ice-concentration near + N & S edges; switch on SEAICErestoreUnderIce=T; use pkg/diagnostics for + snapshot output; same mcPheePiston value as in thsice with + surf-current=0.2m/s. + in input.thsice: similar set-up as in input.thermo (channel with same seaice + initial conditions). +o verification/cfc_example: + - update file "data" with more standard choice (default rotationPeriod, + exactConserv=T, reduce ivdc_kappa to 10, remove multiDimAdvection=F, + set deltaTFreeSurf to deltaTtracer) and update the output. +o pkg/layers: + - fix bolus part so that it compiles with #undef GM_BOLUS_ADVEC; + - ensure that "layers_bolus" is switched to False when useGMRedi=False. +o verification/offline_exf_seaice: + - set all {field}period to zero for constant-in-time forcing (not tested + anywhere else). +o verification/offline_exf_seaice: + - dyn_lsr : use pkg/seaice S/R (instead of pkg/thsice) to advect sea-ice;

(2012). + - In order to be compatible with the default EVP code, this requires changing + the EVP code around a little; and because any small change immediately + breaks the lab_sea.hb87 verification experiment, the reference output is + updated two times (each time the remaining aggrement was only 2 digits): + - after replacing 1/dt by 1*recip_dt with a precomputed recip_dt + - after replacing 1/(1+0.5*dt/tau) by a/(a+1), with a=2*tau/dt + The adjoint test lab_sea.evp also needed to be updated. + - Turn on EVP* by setting SEAICE_deltaTevp as before, and setting + SEAICEuseEVPstar=.true.; for EVP* SEAICE_deltaTevp does not need to be + a factor of SEAICE_deltaTdyn, and you can set the number of EVP steps + explicitly with SEAICEnEVPstarSteps (thereby overriding the default of + INT(SEAICE_deltaTdyn/SEAICE_deltaTevp)). Controlling EVP* is deliberately + kept obscure, because I need to test it a little more. +o pkg/cheapaml: + - fix few incorrect type (_RL/_RS) in subroutine calls. +o pkg/seaice: + - new S/R SEAICE_MAP_RS2VEC (similar to SEAICE_MAP2VEC) to map _RS arrays + to _RL vector; this fixes JFNK code when compiling with "-use_r4" option. +o model/src: + - add a warning if using select_rStar=2 with nonlinFreeSurf <> 4; + change (in input_ad*/data) select_rStar from 2 to 1 for AD verification + experiments global_ocean.cs32x15 & tutorial_tracer_adjsens (+ update output) +o pkg/cheapaml: + - replace "273.1 _d 0" by celsius2K in pkg/cheapaml/cheapaml.F and + update output of experiment cheapAML_box. + - store in CHEAPAML.h coeffs ssq[0:2] for saturation specific humidity, + and set them only in one place (cheapaml_readparms.F). + - replace "273.16 _d 0" by celsius2K & replace "3.14159 _d 0" by constant "PI" + - remove re-setting of main-model parameter "celsius2K" (in cheapaml_readparms) + and re-setting of cheapAML params "lath" & "p0" (in cheapaml_init_varia). +o model/src/the_main_loop.F: + - fix revision 129 : need both ALLOW_ECCO and ALLOW_ECCO_EVOLUTION. +o pkg/seaice: + - remove legacy branch code. + - retire SEAICE_GROWTH_LEGACY and SEAICE_CAP_HEFF accordingly. +o verification/*/code*/SEAICE_OPTIONS.h: + - remove documentation for retired CPP flags (SEAICE_GROWTH_LEGACY, + SEAICE_CAP_HEFF). +o pkg/cheapaml: + - use standard routine (S/R GET_PERIODIC_INTERVAL) to decide when it is time + to load new forcing fields. + - add missing "_d 0" where it's needed; + some editing (improve indentation). + - remove switch to "-r8" compiler option (no longer needed) in verification + cheapAML_box, keep same output (small trucation error differences). +o verification/offline_exf_seaice: + - add thermodynamics only test. +o verification/cheapAML_box: + - split the domain in 8 (2x4) tiles; add MPI and multi-threaded test; + keep same output (same 14 digits for cg2d). + - switch on "-r8" compiler option (some numerical values are missing + the "_d 0") and update output (only 6 digits for cg2d were preserved). + +checkpoint64b (2012/12/24) +o pkg/cheapaml: + - remove un-used variables (Qnet,EmPmR) from pickup files. + - store tendency of advected variables into cheapaml pickup file + and fix the AB-2 restart. +o verification/offline_exf_seaice and lab_sea adjoint: + - switch to new code (#undef SEAICE_GROWTH_LEGACY). + - switch to 4 time steps in offline, consistent with lab_sea. + - match parameters from SEAICE_GROWTH_LEGACY branch in data.seaice. + - update results after change of experiment seaice. +o pkg/seaice: + - remove option SEAICE_MULTICATEGORY; has been replaced with run-time + parameter SEAICE_multDim. Issue a warning if SEAICE_MULTICATEGORY is + still defined since SEAICE_multDim needs to be set to MULTDIM value (from + SEAICE_SIZE.h) to recover previous #define SEAICE_MULTICATEGORY default. +o model/src: + - add run-time parameter to select CG2D solver minimum-residual solution + (in case of a poor convergence). +o pkg/seaice/seaice_lsr.F + - move calculation of matrix coefficients into new + S/R SEAICE_CALC_LSR_COEFFS; for now this routine remains in the same + file; the main purpose of this change is to be able to reuse the code + in S/R SEAICE_PRECONDITIONER + - modify the computation of the residual so that the mass of sea-ice + is not used twice; this simplifies the calculations, but since + the residual is never used except when LSR_mixIniGuess.ge.4---and this is + not tested in testreport---this does not affect the testreport results. +o verification/seaice_obcs: + - disable SEAICE_GROWTH_LEGACY; reset input files to match those of + verification/lab_sea/input.salt_plume; changes results/output.txt* +o model/src: + - adapt quasi-hydrostatic formulation to work with p or p* coordinate. +o pkg/seaice: + - improve description of parameters in seaice_fgmres.F and start + cleaning up the code + - change name of SCALPROD to SEAICE_SCALPROD and modify meaning of + second argument + - add a metric based on grid cell area to SEAICE_SCALPROD; update + results of offline_exf_seaice.dyn_jfnk + - compute initial residual norm in seaice_jfnk based on SEAICE_SCALPROD +o pkg/aim_v23: + - fix an other bug in dissipation heating (grid-cell area was missing). +o model/src + pkg/seaice: + - add global (multi-tile) linear solver for pair of tri-diagonal system + along X and Y lines, respectively for U and V component. + Note: 1) MPI and cube-exchange not yet coded. + 2) probably not accurate for poorly conditioned / large size problem. + - add option for SEAICE_LSR to use global (multi-tile) tri-diagonal solver; + default: not compiled and not used. +o pkg/seaice: + - first attempt at a multi-threaded fgmres solver for the JFNK solver: + introduce bi/bj loops and use global_sum_tile_rl instead of + mpi_allreduce in seaice_fgmres.F + - improve diagnostics output for fgmres solver (seaice_fgmres.F) + - replace a few unnecessary goto statements by if-blocks (seaice_fgmres.F) + - add a verification experiment for JFNK in offline_exf_seaice +o verification: + - change (for now, only fwd test) offline_exf_seaice experiment: + use a re-entrant channel with idealized coastline (trapezoidal shape) + at southern boundary to explore seaice dynamics and thermodynamics + with simple forcing. Main set-up has dynamics+thermo and SST relaxation; + secondary test (input.thsice) use thermodynamics only with SST relaxation. + - add seaice-dynamics only secondary test using LSR and pkg/thsice advection. +o pkg/exf: + - disable "sstExtrapol" when Nr=1 +o verification: + - add new experiment "cheapAML_box" (simple 1 layer set-up from Bruno Deremble) + to test pkg/cheapaml. +o pkg/aim_v23 & pkg/shap_filt: + - fix dissipation heating (erroneous gravity multiplication factor). +o pkg/seaice: + - remove unused field pressPre from jfnk solver + - rename two subroutines in seaice_preconditioner.F +o eesupp/src: + - S/R MDSFINDUNIT avoids reserved unit numbers (scrUnit1, eeDataUnit ...) +o pkg/seaice/seaice_preconditioner.F: fix preconditioner once again + - remove wrong parts of the rhs and the lhs (were in there + because I did not understand the concept of this preconditioner) + - add an exchange between u- and v-sweep. This increases communication + by a factor of two but improves the convergence of jfnk. Ideally, + one would like the u- and v-sweep to be independent. So far within + undocumented ifdefs + - reorganize the extra computations for printing the residuals +o tools/genmake2: + - comment out the "mpif.h" include in NetCDF test programm (for MPI built) + since it's not necessary (and was preventing to use MNC in some cases). + +checkpoint64a (2012/11/16) +o pkg/autodiff: + - improve pkg-internal logical parameter switch (inAd/inFwd mode) so that + autodiff_readparms.F no longer depends on calling order (within + packages_readparms.F) and no longer requires to include ${PKG}_PARMS.h): + rename param turnFreeDriftInAdMode to SEAICEuseFREEDRIFTswitchInAd + and change param SEAICEuseDYNAMICSinAdMode to SEAICEuseDYNAMICSswitchInAd. +o pkg/obcs: + - adding tidal velocity forcing capability to obcs + for usage example, see verification/seaice_obcs/input.tides +o pkg/seaice: + - turn the LSR-relaxation parameters WFAU/V into runtime parameters + SEAICE_LSRrelaxU/V + - introduce runtime parameter SEAICEetaZmethod (=0 by default) +o pkg/aim_v23: + - implement heating from friction (bottom friction and stratospheric drag). +o pkg/shap_filt: + - fix diagnostic "SHAP_dKE" (was 2 time smaller); implement heating from + dissipation but only for Shap_funct=2, active when addFrictionHeating=T. +o model/src: + - move AddMass common block from DYNVARS.h to FFIELDS.h; allow to read-in + time-constant addMass field from file (addMassFile); + - support for heating due to friction (and Kinetic Energy dissipation): + add option, run-time switch and 3-D field array + support code ; each pkg + or S/R can add heating contribution (if there is a sink of KE); the sum is + accounted for as a Temperature tendency term (EXTERNAL_FORCING_T). +o pkg/seaice: + - complete merge of ITD code into seaice_growth.F + from MITgcm_contrib/torge/itd/code/ + no verification so far, but Torge Martin tested + "1-D test case and Beaufort set up; + deliver okay results after 1 model year." + - complete merge of SEAICE_SIZE.h into all relevant routines + - move computation of eta at Z-points into calc_viscosities + + introduce global field etaZ + + add different methods for computing etaZ, for now the old + method (simple averages of eta to Z-points) is hardwired + + replace etaMeanZ by etaZ in seaice_lsr, seaice_calc_residual, + seaice_preconditioner + - simplify computations for SEAICE_ZETA_SMOOTHREG + - seaice_preconditioner: + + replace one remaining press by pressLoc (mistake) + + adjust printing of residuals + - improve I/O of diagnostics of JFNK in seaice_jfnk.F: + + add (SEAICE.h) and rename some counters (initiliased in + seaice_init_fixed.F) + + add _BEGIN/END_MASTER (myThid) around print statements + + print total number of iterations and failures over SEAICE_monFreq + interval to STDOUT + - move control over output-messages by fgmres to seaice_jfnk to save + some operations + - move resetting initial guess for fgmres outside of seaice_fgmres_driver + in order to make restarts with sol .ne. zero (fgmres with restarts) + (seaice_jfnk.F, seaice_fgmres.F) + - seaice_calc_l/rhs.F: replace maskW/S by maskInW/S; this fixes + a serious convergence problem when open boundaries are involved +o pkg/ggl90: fix computation of control volumes for the case of + ALLOW_GGL90_HORIZDIFF (probably not used very often): move control volumes + up half a grid cell from C-centered to W-centered (pointed out by C. Eden) +o pkg/seaice: simplify seaice_evp by avoiding use of extra fields u/vIceC +o pkg/autodiff + - Add inAdMode switch for SEAICEuseDYNAMICS: + SEAICEuseDYNAMICSinAdMode + (extend logic in ADAUTODIFF_INADMODE_SET) +o pkg/seaice + - Step 1 of merging ice-thickness distribution (ITD) code from + MITgcm_contrib/torge/itd/ (author: Torge Martin) + The code implements concept laid out in Thorndike et al. (1975); + code is enabled via CPP flag SEAICE_ITD + nITD (in SEAICE_SIZE.h) defines number of ice thickness categories; + code is not complete yet!! + - SEAICE_SIZE.h now included in almost all seaice routines +o verification (using seaice): + - switch back seaice-dynamics (+ lower SOLV_MAX_ITERS) in ADM exp. + global_ocean.cs32x15.seaice ; update results. + - compile B-grid dynamics in FW test exp 1D_ocean_ice_column ; + - compile C-grid dynamics with #define SEAICE_ALLOW_JFNK in FW test exp + offline_exf_seaice (previously compiling B-grid). +o pkg/exf: + - fix some STOP conditions in exf_check.F (from Aug 28, modifs did not allow + to specify neither just 1 comp of wind or wind-stress, nor no surface momentum + forcing): just replace CPP option ALLOW_ATM_WIND with run-time param useAtmWind. +o pkg/layers (adjust changes from Sept 19): + - do snap-shot output and fill diagnostics from inside iLa loop (layers_calc.F) + this allows to remove "layers_maxNum" dimension from all layers arrays. +o pkg/layers (adjust changes from Sept 19): + - remove ALLOW_LAYERS_OUTPUT ; fix snap-shot and time-ave output ; + - snap-shot extended to all type of layers (not just the 1rst type); + - remove layers variables when corresponding CPP option is undef. +o pkg/layers: + - rename pkg/layers variable and add new output (layer exist & un-weighted + velocity in layer) +o pkg/seaice: + - simplify (?) ocean-drag coefficent computations by using + the same routine in all three solvers (saves some code lines) + - remove global fields DRAGA and DRAGS from C-grid code and + declare them locally in lsr.F (the only place where they are + still used) + - update AD output of lab_sea.evp (very sensitive anyway). +o pkg/seaice: add Jacobian-free Newton Krylov solver for ice dynamics + (Lemieux et al. 2010, 2012). Turn on with the usual SEAICE_ALLOW_JFNK + and SEAICEuseJFNK=.true. A few things to note: + - involves a FGMRES, that is parallel but very inefficient, + because of many scalar products (global sums) in the Gram-Schmidt + orthogonalization method. Needs to be replaced. Original code + from J.-F. Lemieux + - preconditioner for FGMRES is a stripped down version of LSOR + - SOLV_MAX_ITERS is now used for LSOR as a solver and as a + preconditioner. For the preconditioner, the default is set to 10. + - Jacobian times vector is computed with finite differences + - marginally related to JFNK-solver: add a smooth regularization for + zeta with tanh that will improve convergence (Lemieux and Tremblay, + 2009) for any implicit solver (not implemented for EVP because EVP + does not need this regularization in the first place). Define + SEAICE_ZETA_SMOOTHREG in SEAICE_OPTIONS.h to use. +o eesupp/src: + - check in genmake2 that intrinsic S/R flush is available. + - add S/R to flush IO unit (if intrinsic S/R flush is available) + - flush standard & error msg unit before MPI termination + - if debugMode, flush IO unit after printing msg +o pkg/ctrl: + - ctrl_unpack.F, ALLOW_GENARR3D_CONTROL code: fix missing argument in call + to ctrl_set_unpack_xyz. + +checkpoint64 (2012/10/09) +o pkg/shelfice + - in mom_fluxform.F, mom_vecinv.F: + CALL SHELFICE_V_DRAG(bi,bj,k,vFld,KE,KappaRU,vF,myThid) + Bug fix KappaRU -> KappaRV + does not change verification/isomip but may change other setups + (presumably constant KappaRU=KappaRV) + - fix diagnostics SHIU/Vdrag (thanks to Tom Millgate) +o pkg/obcs: + - fixed some indexing bugs in obcs_seaice_sponge.F + - added obcs relaxation subroutines for HSALT and HSNOW + - changes verification/seaice_obcs/results/obcs_seaice_sponge.F +o pkg/seaice: + - add "multicategory" parameterization for snow in analogy to ice, + default is off for now. +o pkg/obcs: + - added obcs_seaice_sponge.F for obcs relaxation of seaice variables; + see verification/seaice_obcs/input.seaiceSponge for example application. + - remove local commom bloc "OBCS_GLOBAL" in obcs_readparms.F and do all the OB + index setting by master-thread. This fix multi-threads Pb in previous modifs. +o pkg/layers : + - add diagnostics to pkg/layers + - move the meat of pkg/layers from layers_calc.F to layers_fluxcalc.F + (from R.Tulloch). Layers_calc.F now calls layers_fluxcalc.F accordingly. +o pkg/generic_advdiff/gad_implicit_r.F : + - fix ADVr diagnostics in case of both implicit vertical advection and diffusion. +o pkg/seaice/seaice_growth.F: + - fix SItflux diagnostics in virtual salt flux + balanceEmpmr case. +o pkg/obcs: + - change default setting of OBCS_UVICE_OLD from defined to undef; + - use new parameter OB_indexNone for null index value (instead of hard-coded 0) + in all pkg/obcs code and in other pkgs; remove k loop in obcs_check_depths.F; + - pass OB_indexNone as (new) argument to S/R CTRL_MASK_SET_[X,Y]Z; + - change OB null index value (OB_indexNone) to -99 ; this fix the problem + with Southern & Western OB at a tile edge (at least in a simple set-up). +o pkg/obcs: + - change settings of OB index in case OB coincides with tile edge (shared by + 2 tiles), so that common OB location is registered by both tiles (instead of + only 1). However, for Southern and Western OB, index value = 0 is not + recognized as valid OB index (=default null value) and needs to be fixed. + - modify accordingly OBCS_BALANCE_FLOW and OBCS_MONITOR (avoid double counting) + - new parameter "OB_indexNone" for null index value (for now, still zero) + to replace hard-coded null index value of zero. +o pkg/exch2: + - improve W2_USE_E2_SAFEMODE (faster) and W2_E2_DEBUG_ON: + always check buffer-size (but outside the loop); move checking for valid + index from W2_USE_E2_SAFEMODE to W2_E2_DEBUG_ON; in W2_E2_DEBUG_ON, + print each tile and point connection only if |W2_printMsg|>= 2 and 3. +o pkg/ctrl (pack & unpack): + - in ctrl_pack.F & ctrl_unpack.F, use the same local file-name variable + (locally defined) for different variables (+ remove the variable-specific + file name in CTRL_GENARR.h). For now, only implemented for GENARR2/3D_CONTROL + (to be extended to other local file names in ctrl.h). +o pkg/flt: + - add a FLT_Iter0 option (similar to PTRACERS_Iter0). +o pkg/mdsio: + - fix missing STOP in mdsio_readvec_loc.F (case ioUnit=0) when file is missing +o tools/genmake2: + - add similar dependences for target EXE_AD & EXE_FTL as we have for EXECUTABLE + (added by Alistair in version 1.51 for building without make depend); + - remove Header files list (H_SRC_FILES) from the dependence of targets + ad_input_code.f & ftl_input_code.f (not clear why it was added in the first + place in version 1.23): this save going through staf when unrelated header + file has been modified. + Note: for an intermediate target (e.g., ad_input_code.f or adtaf) without + "make depend" step, still need to do "make links" before "make adtaf". +o eesupp/src (+ few pkg src files) & genmake2: + - finish to remove ALWAYS_USE_MPI in source code that TAF does not see; + - no longer set ALWAYS_USE_MPI in Makefile (was done by genmake2). + - improve genmake2 checking for ALLOW_${PKG} in CPP_OPTIONS.h files (distinguish + upper/lower case ; account for space between "#" and undef/define) +o pkg/flt (with exch2): + - cleaning: fix so that it compiles; move remaining MPI calls out of flt_exch2.F; + - simplify threads synchronisation; fix (many issues) multi-threaded with MPI. + +checkpoint63s (2012/09/05) +o pkg/ecco: + - remove #ifdef ALLOW_SMOOTH_CORREL3D brackets. + - add more relevant #ifdef ALLOW_SMOOTH ones. + - sort out useAtmWind, useSMOOTH, ctrlSmoothCorrel2D. +o pkg/ctrl: + - CTRL_OPTIONS.h : document CPPs related to smoothing;

The merged routine has two branches, and one activates the 'evolution' + branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now). + In summary, here is what the '10/10 revision' did consist of + part 1: seaice_growth.F revisions 1.71 to 1.75 + - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged. + The emphasis here was on improving readability (e.g. by trying to use meaningful + variable names) and modularity (e.g. by adding arrays to store heff etc. updates). + part 1.5: + - revising the lab_sea experiment to make it a more useful (i.e. stable + and representative of an actual model run). This was done by generating a + (winter) pickup to start from, switching back the main experiment dynamic + solver from evp to lsr, having one of the experiments use the free drift solution. + part 2: seaice_growth.F revisions 1.76 to 1.85 + - Sorting out hard-coded constants that prevented heat and fresh water conservation. + - Sorting out the various fields units and sign (set early on and reset at the end) + to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and + fresh water stock is 'effective ice meters', and >0 implies more ice/snow. + - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks, + and simplifying logical expressions to further improve readibility. + part 3: seaice_growth.F revisions 1.86 to 1.89 + - Re-organize the blocks of code more logically. + - Merging the '_if.F' pieces that add something new. +o pkg/thsice: + - vectorize thsice_solve4temp and thsice_get_exf. + Problem: thsice_solve4temp has an unvectorizable statement that + might also be problematic for TAF + - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This + does not change the verifcation experiment, but will change all + experiments that have this flag undefined (not tested in verification); + a little reorganization to save a few 2D fields and recomputations + - 1st step of revisiting thsice adjoint (major recomp. sorted out) + - 2nd step: fix some store dirs + o seems to work somewhat, i.e. using ifort but not g77 + o likely cause are incomplete init. or recomputation + o start verification/global_ocean.cs32x15/input_ad.thsice +o pkg/obcs: add support for exch2 + - the position of the boundary and prescribed values are specified using + a global domain with exch2 facets stacked + - in x for N,S boundaries (like W2_mapIO=-1) + - in y for E,W boundaries (so E,W boundaries do not overlap) +o pkg/mdsio: add support for writing global sections with exch2 + file layout is as for obcs described above: + - for x-z sections, facets are stacked in x (like W2_mapIO=-1) + - for y-z sections, facets are stacked in y +o pkg/thsice: + - change a few routines for better vectorization: thsice_albedo.F, + thsice_step_temp.F, and in thsice_calc_thickn.F. Results are + not affected, but in particular the latter routine has changed + dramatically (not necessarily easier to read now). + - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops + iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF. +o verification/lab_sea: + - overhaul of the forward model experiments. The main motivation + for this revision is that lab_sea has proven quite fragile (when + changing the sea-ice code, and switching platforms) to a point + when failures were very hard to attribute to specific code problems. + - the suspected reason for this fragility is noise amplification by evp so, + to start with, we decided to replace evp with lsr in the main experiment. + - the input.lsr experiment thus became obsolete and was removed. + - it was replaced with the input.fd experiment that uses an + analytical "free drift" solution as the ice velocity field. + - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp) + will hopefully allow us to discriminate problems due to dynamic solvers + from problems due to the thermodynamic code. input.salt_plume (lsr) allows + us to test additional options, along with the salt plume package. + - Finally a pickup was generated (at the end of a one year run) to + make the tests more representative of an actual model run. Previously + the tests starting point was a 1m thickness of ice everywhere. +o pkg/seaice: + - introducing S\R seaice_freedrift.F that compute the + analytical solution to an approximate ice momentum + equation (i.e. the simple stress/coriolis balance). + - define SEAICE_ALLOW_FREEDRIFT to trigger the computation + of the free drift velocity field, and enable its use. + To actually use the free drift solution as the model ice + velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice. +o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata" + +checkpoint62l (2010/10/04) +o pkg/seaice: + -fix the USE_ORIGINAL_SBI version (for variable freezing point); + -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new + version (with USE_ORIGINAL_SBI undef); +o add hooks for new packages OASIS, the package will follow + (hooks exclude the seaice pkg for now) +o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO + Option to use mdsio_read_whalos.F/mdsio_write_whalos.F, + rather than mdsio_readvector.F/mdsio_writevector.F, within + adread_adwrite.F to read/write adjoint-related tapes to disk. +o eesupp and pkg/mdsio: ALLOW_WHIO + Option to write/read 2D fields to files including tiles halos. + The main purpose is for adjoint related "tape I/O". + The secondary purpose is for debugging phases. + A word on those rather specifically intended purposes. + The code was meant to be stripped down to the bare minimum. + Typically, there is a unique and basic mapping to the global + buffer (tile by tile, then proc by proc, then level by level), and + byteswaps and meta-files are omitted.
