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;

+ - change default (non-MPI) value of myPid (from 1 to 0) to match MPI settings + (so that on 1 proc, get same myPid independently of usingMPI) + - add a stop if multi-procs but usingMPI=F ; stop also if usingMPI=T and + useCubedSphereExchange with EXCH-1 (safer). + - add "if usingMPI" where it was missing (+ start to remove ALWAYS_USE_MPI). +o pkg/ggl90: + - fix bug in filling corner mask array "mskCor" (FILL_CS_CORNER_TR_RL call) + used in ALLOW_GGL90_SMOOTH code. +o pkg/flt: + - fix typo in FLT_WITHOUT_Y_PERIODICITY (the effect was to ignore stopping + floats at the Southern end of the domain). +o eesupp/inc: + - add a list of CPP-options which can be set by Makefile (DEF_IN_MAKEFILE.h); + but not used (and not to be used) anywhere, just for documentation. +o pkg/autodiff, exf, ptracers & seaice (AD & TL output): + - comment out the very nasty "writeBinaryPrec = writeStatePrec" line, since: + a) can damage previously written records in any other multi-record files. + b) if needed, can easily do it cleanly, by calling S/R WRITE_REC_3D_RL/S. +o tools/genmake2: + - define variable MAKE within Makefile and use it in place of 'make'; + - update AD_CONFIG.h (if needed) before building any of the executable + (forward, adjoint or tangent-lin); this involves a 2nd invocation of make; + and add the usual #ifndef/#define AD_CONFIG_H in AD_CONFIG.h; + - always print usual warning comment 'this file is automatically generated' + from script convert_cpp_cmd2defines (+ remove this warning from genmake2). +o pkg/cheapaml: + - updated to correspond to the code used in accepted paper (Nico Wienders). +o pkg/exf: + added run time switch useAtmWind to replace ALLOW_ATM_WIND cpp switch. + ALLOW_ATM_WIND now just sets the useAtmWind default (see exf_readparms.F) + and force defines ALLOW_BULKFORMULAE (EXF_OPTIONS.h). +o pkg/exf, autodiff, ctrl, ecco and seaice: + remove ALLOW_ATM_WIND brackets, or replace them with useAtmWind ones. +o pkg/ctrl, ecco: + allow to compile both ALLOW_U/VSTRESS_CONTROL and ALLOW_U/VWIND_CONTROL. + Depending on useAtmWind, one is inactive, and the other is active (see + exf_getffields.F/exf_getsurfacefluxes.F). +o tools/genmake2: + - improve error msg when failing in 2nd test of check_for_broken_Ff + - fix option '-makefile' short-name (-mf according to genmake2 -help) + - source local config file "genmake_local" just after processing the genmake2 + command arguments (previously done before processing arg). +o pkg/grdchk: + - add a call to TURNOFF_MODEL_IO for Tangent-Linear run (in this case, call + to this routine from cost_final has been dropped in g_cost_final) + - improve printed information (more explicit msg, no longer using "print *," + fix fcpertminus printed value). +o model/src: + - move call to COST_INIT_VARIA out of packages_init_variables.F directly + into initialise_varia.F (just after calling PACKAGES_INIT_VARIABLES): + this prevents getting cost-funct reset in adinitialise_varia recomputations. +o pkg/dic: + - move initialisation of "freefe" array from from dic_biotic_forcing.F to + fe_chem.F: this prevents TAF from dropping this initialisation in TLM code. +o pkg/grdchk: + - grdchk_main.F : added CALL GLOBAL_SUM_INT( ierr , myThid ) + - grdchk_getadxx.F etc. : omit I/O if ierr.EQ.0 +o pkg/autodiff/ctrl/grdchk : + - attempt to sort out what works and what does not, + with regard to I/O, and to warn/stop accordingly. +o pkg/grdchk: + - attempt to fix grdchk in the case of useSingleCpuIO. + - "if ( myProcId .EQ. grdchkwhichproc .AND. ierr .EQ. 0 )" + statements were moved from grdchk_main.F and into + grdchk_getadxx.F grdchk_getxx.F grdchk_setxx.F. + - a global sum is applied to record numbers icvrec/layer + out of grdchk_loc so that they be passed to I/O routines. +o pkg/smooth: + - fix recomputation that appeared with nlfs : use smooth_recip_hFacC, + smooth_hFacW, smooth_hFacS (copied at init_fixed) in 3d case. +o verification/testreport: + - add option '-tlm' for Tangent-Linear test (-adm,-oad,-tlm are all exclusive); + - can also use compressed (gzip) reference output file; + - change format (in pkg/grdchk) of TLM output (+ add forward gradient) + to be easier to collect by testreport. + - update existing TLM output (half out-of-date by more than 3 yrs). + - report NETCDF & LAPACK settings (from genmake2) in output dir. + - report run-time in each individual summary (previously only for AD test);
