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.

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; ALLOW_SMOOTH_CORREL2D/3D, + ALLOW_CTRL_SMOOTH, ALLOW_SMOOTH_CTRL2D, ALLOW_SMOOTH_CTRL3D. + - ctrl.h : document run time params doInitXX, doMainPack, doMainUnpack, doPackDiag, + doSinglePrecTapelev (audodiff param!), ctrlSmoothCorrel2D (new) and + ctrlSmoothCorrel3D (new). + The added ctrlSmoothCorrel2D/3D replace the old ALLOW_SMOOTH_CORREL2D/3D CPP. + - ctrl_readparms.F : initialise ctrlSmoothCorrel2D/3D and read from namelist. + - ctrl_init.F ctrl_pack.F ctrl_unpack.F : switch off ustress/vstress + controls when useAtmWind, and vice versa. + - ctrl_map_ini_ecco.F : UVEL0, VVEL0, edtaux, edtauy cannot be smoothed as tracers. + - ctrl_get_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL2D with + #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel2D, IF useSMOOTH. + - ctrl_map_ini_gen.F : replace #ifdef ALLOW_SMOOTH_CORREL3D with + #ifdef ALLOW_SMOOTH, IF ctrlSmoothCorrel3D, IF useSMOOTH. + - ctrl_set_pack_xy[z].F, ctrl_set_unpack_xy[z].F: + replace ALLOW_SMOOTH_CORREL2D/3D brackets with ctrlSmoothCorrel2D/3D. +o pkg/smooth: + - remove un-necessary includes. + - remove ALLOW_SMOOTH*D and ALLOW_SMOOTH_CORREL*D brakets. + Those CPP options were never defined, and not necessary. +o model/src: + - fix CPP brackets in ini_mixing.F (GM_background_K belongs to gmredi). + - standard treatment of useSMOOTH. +o pkg/autodiff: + - add LOGICAL useGGL90inAdMode, useGGL90inFwdMode, useSALT_PLUMEinAdMode, + useSALT_PLUMEInFwdMode allowing to switch off ggl90 and salt_plume adjoint. +o pkg/exch2: + - add "if usingMPI" where it was missing (in exch2_rx?_cube*.template) + + start to remove ALWAYS_USE_MPI in source code that TAF does not see. + - make new S/R W2_MAP_PROCS out of w2_eeboot.F to setup exch2 CommonFlag + and tiles to process mapping. + - re-arrange 3 header files (W2_EXCH2_PARAMS.h, _BUFFER.h & _TOPOLOGY.h) + moving /EXCH2_FILLVAL_RX/ & /W2_EXCH2_COMMFLAG/ to W2_EXCH2_TOPOLOGY.h; + rename "exch2_tProc" to "W2_tileProc" and move seting of e2FillValue_RX + from w2_eeboot.F to w2_readparms.F. +o eesupp/src: + - set exchNeedsMemsync & exchUsesBarrier according to "usingMPI" (instead of + ALWAYS_USE_MPI) + moved from ini_communication_patterns.F to eeset_parms.F; + also move setting of exchCollectStatistics from exch_init.F to eeset_parms.F + - in eedie.F and all_proc_die.F, always call MPI_FINALIZE when ALLOW_USE_MPI + is defined (remove condition on usingMPI) to match cases where MPI_INIT + has been called. + - fix bug I put in previous modif of exch_sm_3d_rx.template (not much used); + - 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);

fix S/R CTRL_SMOOTH ; update AD experiment + code_ad/*.F src files; add new option-file in pkg/admtlm + corresponding + includes; + - model/src: add PACKAGES_CONFIG.h wherever ALLOW_AUTODIFF[_TAMC] is used. + - ALLOW_DIFFKR_CONTROL: add a stop in S/R CTRL_CHECK in case ALLOW_3D_DIFFKR + is undef; also define /DYNVARS_DIFFKR/ common block in DYNVARS.h when + ALLOW_DIFFKR_CONTROL is defined, to allow to compile and reach this stop. + - update option-file CPP_OPTIONS.h of all AD experiments: + * no longer include PACKAGES_CONFIG.h ; + * includes ECCO_CPPOPTIONS.h if PACKAGES_CONFIG.h has been included ; + * def/undef ALLOW_3D_DIFFKR independently of ALLOW_DIFFKR_CONTROL (before + including ECCO_CPPOPTIONS.h). +o pkg/cost, pkg/ctrl, pkg/ecco option-file: + - clean-up and split content of old pkg/ecco/ECCO_CPPOPTIONS.h file into + separated pkg option-file (done according to old doc from ECCO_CPPOPTIONS.h, + not necessary accurate). + - add a template for option-file ECCO_CPPOPTIONS.h, mostly empty, in + pkg/autodiff, i.e., the 1rst pkg to compile for adjoint built, with lines to + deliberately break compilation (a remainder that it needs to be customized) + - in pkg/ecco, includes ECCO_OPTIONS.h instead of COST_OPTIONS.h + - rename COST_CPPOPTIONS.h to COST_OPTIONS.h + - rename CTRL_CPPOPTIONS.h to CTRL_OPTIONS.h +o tools/genamke2: + - check for lapack. +o pkg/cost and pkg/ecco : attempt to sort out some of the limiting intricacies. + - pkg/cost.cost_final.F : allow for use of pkg/ecco and pkg/cost cost functions + jointly.

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. Indeed the (*_WH*) code is not + meant to generate user friendly outputs of various shapes and forms. + Rather it is intended, for the knowledgeabale developers, + to be largely independent of the many mdsio options, to allow + outputs of tiles+halos in debugging phases and in adjoint runs, + and to allow some flexibility in tuning (adoint) I/O depending on each + file system behavior. With regard to tuning, most of the potential knobs + (to leave files open, to allocate the I/O indep. of usesinglecpuio, + to specify directories, to specify the typical size of I/O calls, etc.) + are not yet included, and will be added if they prove useful. +o pkg/seaice: + fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F +o pkg/seaice: + new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty + code (seaice_budget_ice_if.F) which enable to recover old standard + code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined. + temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F. +o model/src (rStar): + use simple average (not area weighted) of rStarFac at U,V point when using + vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection) + update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20. + +checkpoint62k (2010/09/17) +o adjoint + * changed verification/global_ocean.cs32x15 ;
