7    checkpoint58a_post
8    o shelfice:
9      - separate shelfice load anomaly from pload (breaks with time
10        dependent forcing), => introduce constant field shelficeLoadAnomaly.
11        Its default is 0., but it may be computed more cleverly from (unknown)
12        t- and s-profiles (tRef, sRef) and actual EOS. For now this has to be
13        done offline. A good approximation of the pressure load anomaly is
14        necessary to avoid large initial adjustment processes underneath
15        deep-reaching shelfice.
16      - small fix in ISOMIP shelfice_thermodynamics
17      - add more sophisticated thermodynamics of Hellmer (1989), this is
18        now the default
19      - give a few constants more intuitive names
20    o add code to balance EmPmP and Qnet at the end of do_ocean_physics. Useful
21      if bulk formulae are used in long integration (especially EmPmR). Turn
22      on with balanceEmPmR = .true. or balanceQnet = .true. in data, PARM01
23      if balancePrintMean, the imbalance that is substracted is printed to
24      STDOUT.
25    o fix bug (typo) in obcs_apply_eta.F
26    o add a new package shelfice which enables us to model the circulation
27      underneath shelf-ice with draughts of hundreds of meters.
28     - works
29     - to do: + include improved thermodynamics
30              + check whether kSurfC (from model/inc/SURFACE.h) can be used
31                instead of new field kTopC
32              + can we use topoFile, Ro_surf and existing code in ini_depth.F
33                instead of new field R_shelfIce and new code in ini_depth.F
34                and ini_mask_etc.F?
35              + adjust vertical mixing schemes?
36    o seaice pkg:
37     - add a cpp-flag to include a simple formula for a salinity dependent
38       freezing point of sea water at the surface
39     - change the contents of SEAICE_TEST_ICE_STRESS_1 so that zonal and
40       meridional stresses are now different (and hopefully correct)
41    o AIM pkg: change threshold on large-scale condensation to conserve Heat.
42       update results of aim.5l_LatLon test ; fix title & units of AIM diagnostics
43       and  change 3 diagnostics names (OSR,OSRCLR,KM -> TSR,TSRCLR,DRAG)
44    o pkg/diagnostics: add options and parameters for regional-statistics
45       diagnostics ; define regions by reading a region-mask from a file
46       (might add other options later)
47    o pkg/bulk_force:
48     - add option and parameters to use AIM surface-flux formulae.
49     - Change loading part: S/R BULKF_FIELDS_LOAD only take care of bulkf_fields ;
50       others forcing fields (defined in PARM05, parameter file "data") are loaded
51       from S/R EXTERNAL_FIELDS_LOAD, as usually (with useBulkforce = T or F).
52     - initialise all bulkf_fields in bulkf_init.F ; do in-lining of exf_bulkcdn.F
53     - use the right EXCH call for uwind,vwind (to work on CS-grid).
54     - re-arrange header files (move parameters from BULKF.h to BULKF_PARAMS.h)
55       and parameters (note: calcWindStress replaces .NOT.readwindstress).
56     - cleaner interface with pkg/thSIce (new S/R THSICE_GET_PRECIP).
57    
58    checkpoint58
59    o add "--embed-source" option to genmake2 which, when the supporting
60      tools can be compiled (as determined by genmake2) will turn on the
61      embed_files package which then embeds the entire MITgcm source code
62      (*.[fFhc] + Makefile) used for the build within the executable
63      - requested by CNH but off by default
64      - adds a paltry <9MB to the mitgcmuv executable in most cases
65      - only writes the output when useEMBEDSRC in eedata is true
66    o clean up 3-dim. relaxation codes:
67      * Fix I/O inconsistency in pkg/rbcs: replace precFloat32 by readBinaryPrec
68      * Remove 3-dim. relaxation code from pkg/exf (now use only pkg/rbcs)
69      * Thanks to Tom Haine for testing!
70    
71    checkpoint57z_post
72    o make CG3D solver compatible with Free-surface at k > 1 (p-coordinate):
73      affects output (@ truncation level) of exp. plume_on_slope ; updated.
74    o fix the pickup behavior for obcs in combination with ptracers
75    o fix a bug in ptracers_external_fields_load
76    o no AB-2 at the first iteration for Gw (consistent with Gu,Gv,Gt,Gs ...)
77      affects results of NH experiments (but all our NH tests have Gw[it=1]==0 !!)
78    o transfered surface NH pressure to eta field (if exactConserv).
79    o gmredi: fix bugs in slope tapering ldd97 (depthZ had the wrong sign)
80         and update lab_sea output.txt file.
81    o completing 3-dim. relaxation code: additional term
82         1/tau*( theta(i,j,k) - thetaStar(i,j,k) )
83      in S/R EXTERNAL_FORCING_T (file external_forcing.F)
84      * At compile time, in "EXF_OPTIONS.h" set
85          #define  ALLOW_CLIMTEMP_RELAXATION
86          #define  ALLOW_CLIMSALT_RELAXATION
87      * At runtime in "data", under &PARM03 set (e.g., units in seconds)
88          tauThetaClimRelax3Dim = 15552000.0,
89          tauSaltClimRelax3Dim  = 15552000.0,
90      * 3 cases:
91          1) Use a constant-in-time 3-dim. field
92          2) Provide 12 3-dim. fields corresponding to Jan., ... , Dec.
93          3) Real-time relax. to time-evolving prescribed field
94    o Adding Laplacian-type smoothness constraint on
95      initial and boundary (forcing) controls (ic, bc)
96      * enable at compile-time via
97        ALLOW_SMOOTH_IC_COST_CONTRIBUTION, ALLOW_SMOOTH_BC_COST_CONTRIBUTION
98      * enable at run-time via mult_smooth_ic = 1, mult_smooth_bc = 1
99      * Absolute scale somewhat unclear so far
100      * no area weighting was included since no other cost term does so far
101    
102    checkpoint57y_post
103    First step for a NLFS adjoint
104    o initially suppress rStar (new flag DISABLE_RSTAR_CODE)
105    o new init. routines for calc_r_star, calc_surf_dr
106    o still need to deal with ini_masks_etc
107    o testreport seemed happy
108    checkpoint57y_pre
109    
110    o obcs: always reset wVel & eta (to zero or prescribe it) at the OBs.
111    o add new package rbcs (for relaxing ptracers at boundaries/depth/surface etc)
112    o add new offset feature to offline pkg (plus minor cleanup)
113    o cfc fixes for final year of integration
114    o clean up GCHEM_OPTIONS.h/DIC_OPTIONS.h (all options should
115      be in GCHEM_OPTIONS).
116    
117    checkpoint57x_post
118    o fix testreport Pb in multiple test experiment.
119    o cleanup our namelist syntax in verification:
120      - make it more F95 standards compliant (some work still needed)
121      - allows the vast majority of our tests to work with gfortran
122    o Non-Hydrostatic:
123     - put all NH variables (formerly in DYNVARS.h & GW.h) in NH_VARS.h
124     - fix exchange calls for CS-grid using the new EXCH_S3D_RL.
125    o Allow to apply AB on T,S rather than on AB(gT,gS):
126     - implemented within #ifdef ALLOW_ADAMSBASHFORTH_3
127     - use the same arrays (gtNm,gsNm) to hold tracer field at previous
128       time-steps (if AB(T,S)) and tendencies (if AB(gT,gS)).
129     - need a "clever" read_pickup to restart from the other AB formulation
130    o move local commom bloc /GlobalLo/ (used for singleCpuIO) in EESUPPORT.h
131    o remove some unused variables (reduces number of compiler warnings)
132    o adjoint
133      * Disable useVariableViscosity for adjoint for time being
134        (there are a number of extensive recomputations)
135      * Initialize certain variables needed for adjoint
136    
137    checkpoint57w_post
138    o pkg/mdsio: use MAX_LEN_FNAM (instead of hard coded 80) for file-names
139                 fix the singleCpuIO RS version of MDSWRITEFIELD
140       and add a WARNING if using globalFiles=T with multi-processors.
141    o write grid-file(s) in only one format (MDS or MNC): default=MNC (if
142      using MNC); can force MDS output by setting writegrid_mnc=F in data.mnc
143    o tracer advection scheme:
144      add DST-2 (=Lax-Wendroff) & 1rst order upwind schemes (the way to get
145       those 2 schemes before, changing GAD_FLUX_LIMITER.h + to recompile,
146       was not very convenient).
147      add implicit version for DST-3 & DST3_Flux_Limit vertical advection;  
148       (further tests needed for the implicit DST & Flux-Limiter schemes).
149    o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
150      and sRef for convenience, handy, when you want to initialize
151      ptracers in a large domain with a constant non-zero value. Also,
152      untangle ptracers_init.F a little.
153    
154    checkpoint57v_post
155    o change dome exp. to use variable viscosity in side-drag terms.
156    o remove all the files from the cfc_offline test since they are now
157      incorporated into tutorial_cfc_offline which has been producing
158      identical results for a few days of testing
159    o add new parameter: sideDragFactor to enable half-slip-side BC
160      and change side-drag S/R to use viscosity from mom_calc_visc
161      (can switch back by setting sideDragFactor=0.); affects results at
162      truncation level; regenerate output for exp.: global_ocean.cs32x10(x3),
163       global_ocean_ebm, global_ocean_pressure, matrix_example & MLAdjust(x5).
164    o vorticity & strain are now computed without masking, to account for
165      no-slip-side BC in variable viscosity calculation ; mask is applied
166      anyway later on, before computing advection/coriolis terms.
167    o modify exp4 to test new obcs support for reading from external files
168      and for passive tracers
169    o fix behavior of ptracers_monitor when monitor output is written to a
170      netcdf-file; still not independent of monitor.F (writes in the same
171      file).
172    o change default value of tRef (put a uniform, meaningful value for ocean
173      & atmos) and initialize sRef (was missing, as Martin mentioned).
174    o Redefine viscC?Leith*.  Change the coefficients of Leith viscosity
175      to be proportional to enstrophy dissipation length.  Thus,
176       viscC?leith?_new=pi*(viscC?leith?_old)^(1/3)
177      This is now consistent with Smagorinsky and with the manual.
178    
179    checkpoint57u_post
180    o OBCS and PTRACERS: add open boundary support for passive tracers
181      - either use homogenous (pseudo) v.Neumann conditions or prescribe
182        OB-values from file; this is not different from the way theta and salinity
183        are treated
184      - however, Orlanski-radiation conditions are not supported, and the model
185        will stop if you use pTracers and Orlanski at the same time.
186      - beefed up the rountine obcs_external_fields_load: now only those open
187        boundary values are overwritten with values from files for which there
188        are really files, otherwise the OB-fields remain untouched. This makes
189        it possible to use different OBs at different ends of the domain (as
190        with EXF)
191    o reduce number of exch calls in shap_filt (s2).
192    o CS-grid: fix divergence contribution to Leith viscosity. Affects (@
193      truncation level) 4/5 MLAdjust test results (11&12 digits match).
194    
195    checkpoint57t_post
196    o test biharmonic viscosity + no-slip with exp: global_ocean.cs32x15.viscA4
197    o finish adding brackets (coriolis S/R, vecinv) in multi-terms sum to get
198      same truncation, independent of the face number: affects affects several
199      test. exp.: Update global_ocean.cs32x15 (+.thsice) & MLAdjust (all 5).
200    o fix bug in mom_v_sidedrag (biharmonic viscosity was counted 2 times);
201      note that biharmonic viscosity + no-slip was not tested in any experiment.
202    o fix bug in non-linear free-surf side-drag ; generate new output for
203      global_ocean.cs32x15(+.thsice) & global_ocean_pressure.
204    o make mnc honor the writeBinaryPrec flag for most kinds of output
205    o eesupp: split EEPARAMS into EESIZE/EEPARAMS and add a vector global sum
206    o minor change in averaging W (mom_vi_?_vertshear.F) that affects truncation
207      error; update output from global_ocean.cs32x15(+.thsice) & MLAdjust (all 5).
208    o add brackets in multi-terms sum to get same truncation, independent of
209      the face number (manage to get exactly same value of gU,gV at the cs-edge)
210      affects several test. exp. Update global_ocean.cs32x15 (+.thsice).
211    o Clean, new version of mom_calc_visc.  Adds a new feature, viscAhRemax
212      and viscA4Remax, which allow one to limit the minimum viscosity by specifying
213      a maximum grid-scale Reynolds number.  Also, changes all length calculations
214      in the case of grid anisotropy to geometric mean of dx**2 and dy**2.
215      Suggested values of viscosity parameters found in mom_calc_visc.
216      Many new viscosity diagnostics available.
217    
218    checkpoint57s_post
219    o Add clearing-house for viscosity calculations, mom_calc_visc and
220      correct numerous bugs in LeithD and Smagorinsky discretizations.  
221      mom_calc_visc now allows for Smagorinsky, Leith and LeithD to be
222      used simultaneously, and to be used in mom_vecinv and mom_fluxform.
223      Mom_vecinv can be used with standard viscous calculation (mom_vi_hdissip.F)
224      and with Strain-Tension viscous term calculation (mom_hdissip.F).  
225      The Strain-Tension form is now called with useStrainTensonVisc=.true.
226      ViscAhStrain and viscAhTension are now retired.
227    o diagnostics "VISCAHD" & "VISCA4D" replace "VISCAH" & "VISCA4".
228    o In response to JMC's bug report, genmake2 now ignores any soft-links
229      that it finds in the *current* directory when searching for files.
230      Soft-links found in any other source directories will still work as
231      they did before.
232    o add HAVE_SETRLSTK define and useSETRLSTK flag (eedata) which calls
233      a C routine to unlimit the stack size
234    o mnc-ify pkg/aim snapshot vars
235    o mnc-ify pkg/land as requested by Daniel
236    o various changes to mnc including:
237      - all files use the new "BASENAME[[.ITER].{t|f}NUM].nc" format
238      - output can now be grouped so that all files within a group
239          change the ITER portion of their names in lock-step together
240      - can now read ("global") PER-FACE (in addition to PER-TILE) files
241          and works with both EXCH1 and EXCH2 (but needs more testing)
242      - writing works for all verification test cases w/ g77 on Linux
243    
244    checkpoint57r_post
245    o make MNC variable initialization happen earlier
246    o add diagnostics for (almost) each term of the momentum Eq.
247    o remove SST,SSS,UVEL_k2,VVEL_k2 diagnostics.
248    o move pkg timeave out of pkg-groups "oceanic" & "atmospheric" (pkg/pkg_groups)
249    o remove MINIMAL_TAVE_OUTPUT option ;
250      add "dumpInitAndLast" to replace "nodumps" (and MINIMAL_TAVE_OUTPUT).
251    o move some basic S/R (used elsewhere in the code) from pkg/mdsio to eesupp/src
252      allows to compile without pkg/mdsio (& test successfully hs94.1x64x5)
253    o add MNC output for adjoint of EXF (adexf), SEAICE (adseaice)
254    o add time-dependent SST, SSS control
255    o cost terms in ecco/ modularized (new cost_generic.F)
256    o cost_averages routines are modularized (new cost_averagesgeneric.F)
257    o new infrastructure for seaice model vs. obs misfits in seaice/
258      * driver from the_main_loop.F is seaice_cost_driver.F
259      * first term is AREA vs. SMR observation misfit (ALLOW_SEAICE_COST_SMR_AREA)
260      * gradient check in Exp. 6a of natl_box_adjoint/
261    o natl_box_adjoint input_seaice for Lab. Sea now available online via wget
262      (see README file)
263    
264    checkpoint57q_post
265    o fix initialisation Pb in calc_gw (get NANs in exp5 with g77)
266    o fix annoying months-old bug in mnc/mdsio output for seaice pkg
267      - bug was reported by Jean-Michel and Ian Fenty
268    o fix initialization Pb in AIM-Ocean coupled model (aim_sice2aim.F)
269      update exp. cpl_aim+ocn output.
270    o Implement 4-level checkpointing: AUTODIFF_4_LEVEL_CHECKPOINT
271      Needed for high-res. runs with large global files
272      to be able to limit tapelev size
273    o Changed some tests for adjoint:
274      * carbon/ now tests AUTODIFF_2_LEVEL_CHECKPOINT
275      * natl_box_adjoint/code_bulk/ tests AUTODIFF_4_LEVEL_CHECKPOINT
276      * global_ocean.90x40x15/ back to default 3-level checkpointing
277    o Modifications to enable scripted COMMON to MODULE conversion
278      * verification/OpenAD/code/ has necessary scripts and description;
279      * converts, compiles and runs successfully;
280    
281    checkpoint57p_post
282    o reading of delXfile & delYfile moved from ini_parms.F to ini_grid.F
283    o move ${PKG}_MNC_INIT from ${PKG}_READ_PARAMS to ${PKG}_INIT_FIXED
284      (already the case for some pkgs, including recent MNC_init, e.g. thsice)
285    o call CALC_GW from DYNAMICS (instead of from FORWARD_STEP)
286    o Dissipation & phiHyd gradient are always added to gU,gV in timestep.F
287      (was already the case for dissipation with mom_vecinv,
288       and also the case for grad.PhiHyd when staggered-timeStep)
289      This will allow to put dissipation out-off the AB time-stepping.
290     Unfortunately, affects truncation error. Update output of exp. that "fails"
291      (cg2d matching number) and leave the others for later: front_relax(10),
292      global_ocean_pressure(10),ideal_2D_oce(10),internal_wave(9),lab_sea(12),
293      matrix_example(7!),natl_box(12),plume_on_slope(11),vermix(12x3,11x2).
294    
295    checkpoint57o_post
296    o fix MNC/MDSIO flags in PTRACERS so that (1) it works, and
297      (2) its ready to be documented during the 20050801 DocFest
298    o MNC-ify the gmredi package -- tested and works w/ and w/o mnc
299      for ideal_2D_oce and lab_sea on linux_ia32_g77
300    o set to #undef CTRL_SET_OLD_MAXCVARS_30
301      in global1x1_tot/code_seaice_adj to access indices 32, 33
302      (worth another tag)
303    
304    checkpoint57n_post
305    o adding precip control xx_precip 32
306    o adding swflux control xx_swflux 33
307    o Replacing 10 forcing penalty cost routines by 1 generic.
308    o Implementing partitioning in time-mean and variable adjustment
309      for atmos. state.
310    o Time-mean constant error is now read in data.ecco (instead of hard-coded)
311    o in natl_box_adjoint:
312      * updated exp 1 to 10
313        (but does not have time-mean vs. variable split results yet)
314    o updated global1x1/*_seaice_adj/
315      to incorporate latest changes
316    o enable useSingleCpuIO for mdsio vector routines
317      (applies in particular to tapelev I/O)
318    o removed inefficient K-loop in all active_file*control*.F
319    
320    checkpoint57m_post
321    o re-arrange exp. adjustment.cs-32x32x1 (adjust_nlfs.cs-32x32x1 merge into)
322      and advect_cs (use EXCH-2 and standard cs-32 grid files).
323    o pkg/exch2: filling of face-corner halo regions is optional
324      (ifdef W2_FILL_NULL_REGIONS) and is turned off by default.
325    
326    checkpoint57l_post
327     tag before updating tutorials (pre-release-2)
328    o add cos & sin of grid-direction orientation angle (curvilinear grid only,
329       for output and interpolation of input fields onto model grid)
330    o fix radius in mom_v_metric_cylinder.F (wrong by dy/2).
331       Affects results of exp. rotating_tank ; update output.txt.
332    o pkg/diagnostics: 2 new S/R to fill a diagnostics using a scaling factor
333          and taking the square quantity and/or using a fraction-weight field.
334    o fix aim_diagnostics_init.F mate numbers.
335    o add mnc output capability to diagnostics/diagstat and update
336      our cvsignore files for the ACSII output generated
337    
338    checkpoint57k_post
339    o lab_sea now uses diagnostics package and provides a suite of
340      new EXF diagnostics output.
341    
342    checkpoint57j_post
343    o exf
344      * bug fix in exf_bulkformulae for psimh (spotted by Eliyahu Biton):
345        Bracket missing in eqn. for psimh (eqn. 7 of Large & Pond, 1982);
346        terms -2*ATAN(x) + pi/2 were added to both stable and unstable case.
347      * extended diagnostics output
348        - now includes all EXF variables
349        - hs, hl moved to common block
350        - separate S/R for diagnostics, called after ctrl vector is added
351        - name changed for EXFsw -> EXFswnet, EXFlw -> EXFlwnet
352        - EXFqnet contains true Qnet (i.e. includes qsw)
353      * updated verif. lab_sea, global_with_exf
354      * Rearranging hflux (exf_mapfields -> exf_getforcing)
355        to ensure that diagnostics sees a true EXFqnet
356    o add matlab scripts for CS-grid vectors (in utils/cs_grid)
357    o diagnostics pkg: change pointers so that 1 diagnostic can be used
358      several times with different frequencies.
359    o mnc-ify the thsice package as requested by Daniel Enderton
360      - the monitor--MNC output needs work
361      - many attributes need to be added (most are currently blank)
362    o mnc-ify theaim_v23 package as requested by Daniel Enderton
363      - many attributes need to be added (most are currently blank)
364    o remove "groundAtK1" & "rkFac" (replaced by usingPCoords & -rkSign)
365    o add Sadourny like discretization to the 4th.O vorticity advection scheme
366    o fix bug in rStar code (calc_r_star.F) when used with topo/bathy.
367      update output.txt from: aim.5l_cs (& .thSI), cpl_aim+ocn,
368         fizhi-gridalt-hs and global_ocean.cs32x15 (& .thsice).
369    o fix few little things to avoid floating error with -ftrapuv (ifort v9)
370     (ini_spherical_polar_grid.F, calc_r_star.F, monitor/mon_surfcor.F)
371    
372    checkpoint57i_post
373    o Diagnostics package was changed: diagnostic allocation is now deactivated
374      by setting an empty file name in the namelist (used to be by setting 0 frequency)
375    o momentum advection (VI form) options: activate 4th.O vorticity Coriolis ;
376      add 1rst Order upwind vertical Shear.
377    o add a quick fix for A/B checkpointing in OFFLINE mode
378    o add IGNORE_TIME define and -ignore_time option to genmake2 as an
379      end-run around the C/Fortran linking horror in eesup/src/timers.F
380    o added pkg/runclock: allows user to terminate run based on wall clock
381    o added non-hydrostatic scaling parameter: nh_am2
382    o pkg/my82: futile attempt to make results compiler-independent by adding
383      some "_d 0", etc. no effect.
384    o for mnc output, fill the 'T' coordinate var with myTime and create a
385      separate 'iter' variable for iteration count
386    o pkg/diagnostics:
387      add new capability: output of Global/Regional & per-level statistics ;
388      tested against monitor output (including land & thSIce) on various exp.
389    o make seaice-pkg I/O type flags (MNC/MDS) more standard.
390    
391    checkpoint57h_done
392      tag after changing user customized files (DIAGNOSTICS_SIZE.h,
393      data.diagnostics, data.gchem, data.ptracers) is done.
394    
395    o pkg/diagnostics: prepare for Global/Regional statistics.
396      add 2nd namelist in data.diagnostics and update DIAGNOSTICS_SIZE.h
397    o remove "baseTime" (no used) from arg. list of DIFF_BASE_MULTIPLE
398      and rename it: DIFFERENT_MULTIPLE
399    
400    checkpoint57h_post
401    o move tIter0 from data.gchem to PTRACERS_Iter0 in data.ptracers
402    o pkg/diagnostics: change output frequency, now in seconds (instead
403      of Nb of iterations). This requires to change data.diagnostics.
404    checkpoint57h_pre
405    
406    o in mnc, let the user create the output dir if both mnc_outdir_date
407      and mnc_outdir_num are false
408    o add fflags() to pkg/diagnostics which allows one to specify, on a
409      per-file basis, the file precision [default behavior is unchanged]
410    o added diagnostics to pkg/kpp, including computation of mixed layer
411      depth based on a temperature/density criterion
412    o updated verification/natl_box to test the new pkg/kpp diagnostics
413    o bugs fixed (with useAbsVorticity=T & with useJamartMomAdv=T)
414    o test AB-3 code with 4th.Order advection scheme (advect_xy/input.ab3_c4)
415    o fix mnc flags in pkg/seaice so that they are "owned" by seaice,
416      not mnc -- this mistake was found by JMC and is now corrected
417    
418    checkpoint57g_post
419    o add Adams-Bashforth 3rd Order time stepping:
420      - default remains AB-2 (#undef ALLOW_ADAMSBASHFORTH_3)
421      - not yet implemented with NH, CD_Scheme, pTracers, MNC_pickup ...
422    checkpoint57g_pre
423    
424    o make lambda[Theta,Salt]ClimRelax spatially varying
425      (default remains spatially uniform constant based on tau)
426    o added new control variables
427      * init. uVel, vVel, etanN
428      * lambda[Theta,Salt]ClimRelax
429    o separate masks used for ctrl_pack/unpack 'from write_grid' output
430      (suggested by G. Forget)
431    
432    checkpoint57f_post
433    o add parameter "baseTime" = model base time = time at iteration zero
434      new function DIFF_BASE_MULTIPLE (replace DIFFERENT_MULTIPLE) to
435      account for baseTime shift
436    o move Coriolis arrays from PARAMS.h to GRID.h
437    checkpoint57f_pre
438    
439    o mnc-ifying the seaice package
440    o introduced an alternative length scale calculation for use in the limiting
441      maximum viscosity (off by default, see mom_vi_hdissip.F for details)
442    o S/R ptracers_calc_diff: argument list bug for CALL KPP_CALC_DIFF_S
443    o added modified Leith scheme with viscosity proportional to grad(Hdiv)
444      as well as grad(vort3).  Made it compatible with both approximate form
445      for the cubed sphere and full form of these gradients.  Added flag
446      useFullLeith to select between approximate and full form.  
447    o add "d0" in getcon.F to reduce differences between compilers/platforms
448      update output.txt of exp. fizhi-gridalt-hs
449    o change port_rand funtion to allow to set the seed.
450    o fix obscure MNC bug involving conversion between reals and integers
451      - it caused no problems with certain (eg. gcc, ifc) compilers but the
452        new version is now more standards-compliant
453    o adjoint-related modifications
454      * gad_dst3_adv_?: to be able to use advscheme=30 in adjoint
455      * gad_calc_rhs: fool adjoint, revert to advscheme=30 in reverse when using 33
456      * mom_vi_hdissip: to be able to use Leith scheme in adjoint
457    
458    checkpoint57e_post
459    o Adding eddy stress controls a la Ferreira et al.
460    checkpoint57e_pre (actually was tagged: eckpoint57e_pre)
461    
462    o fizhi pkg: fix AtoC and CtoA when called with same input & output array
463      update output.txt of exp. fizhi-gridalt-hs
464    o add more "Z" dimensions and associated coordinate vars to MNC
465    o pkg/exf: added twoDigitYear capability for option useExfYearlyFields
466    o parameter calendarDumps: when set, approximate months (30-31 days) and years
467      (360-372 days) for parameters chkPtFreq, pChkPtFreq, taveFreq, SEAICE_taveFreq,
468      KPP_taveFreq, and freq in pkg/diagnostics are converted to exact calendar
469      months and years.  Requires pkg/cal.
470    o diagnostics: add pickup functionality
471      - off by default for backwards compatibility
472      - current version only uses MDSIO -- MNC will be added
473    o allow to use pkg diagnostics for LAND pkg output & Shapiro Tendencies.
474    o pkg/shap_filt: fix for multi-tiles per face (CS-grid with EXCH2)
475    
476    checkpoint57d_post
477    o pkg/thsice used in the ocean: fix tile Pb related to sIceLoad forcing
478    o modify verification/ideal_2D_oce so that it tests the creation of mnc
479      output from the diagnostics package
480    o temporary fix in EXCH2_UV: add a 3rd call to fix the 24.tiles CS-grid set-up
481    o make genmake2 more portable by using ".$FS" instead of ".f" for more
482      of the test compilations (eg. IBM xlf on Mac OSX w/HFS filesys)
483    o add coordinate variables to the MNC output from the diagnostics package
484    o change MNC-flags default value: true when useMNC=TRUE
485    o add a "readgrid_mnc" flag to MNC and give model/src/ini_curvilinear_grid.F
486      the ability (off by default) to read the grid information using MNC
487    o lab_sea: use LSR_ERROR=1.E-12 for testing ; update output.txt
488    o diagnostics: fix a bug (sub-set of levels); keep full precision when averaging
489    o do snap-shot diagnostics at the middle of the time-interval (instead of
490      at the end).
491    o update exp. aim.5l_cs (use default LAND_OPTIONS.h file) and add
492      new test for AIM with thSIce + slab-ocean
493    o cpl_aim+ocn test: update output (optfile & default GMREDI_OPTIONS.h)
494    o move state variable diagnostics to the beginning of the time step ;
495      (note: still needs some work specially for snap-shot diagnostics)
496      duplicate & replace UVELVVEL diagnostics with UV_VEL_C & UV_VEL_Z
497    
498    checkpoint57c_post
499    o Change testing option (-ieee) to get closer agreement between g77 & ifort
500    o generate new output.txt files on faulks with g77 & the new -ieee option
501    checkpoint57c_pre
502    
503    o add "_d 0" in freeze ; change some "FLOAT" to "DFLOAT" and went back (TAF);
504      update output.txt of exp. global_ocean.90x40x15
505    o fix in ini_eos.F (one "_d 0" was missing): now g77 & ifc give much closer
506      results; update global_ocean_pressure & global_ocean.cs32x15 output.txt
507    o add saltFlux(+File) forcing capability with periodicExternalForcing
508    o allow to use pkg diagnostics for GM-Redi & ThSIce output
509    o diagnostics_fill: fill in up to sNx+1 or sNy+1 (if U,V or Z pt) for mnc.
510    o improvements for the MNC output from DIAGNOSTICS:
511      - correct handling of the unlimitied dimension
512      - all dims now have associated coordinate variables
513      - variables located at U, V, and Corner ("Z") points are now written
514        with the correct horzontal dimensions (eg. 'Xp1', 'Yp1') so that
515        *all* data points are output
516    o added seaice_summary.F and removed obsolete ALLOW_SEAICE's from pkg/seaice
517    o added pkg/seaice/seaice_monitor.F
518    o mdsio_readfield.F can now read files visible only to master MPI process.
519    o pkg/seaice: some test code for ice-modified ocean stress
520    o exf_getffields interpolation defaults to bilinear for all scalar forcing
521      fields (remains bicubic for wind velocity and stress).  This avoids, e.g.,
522      spurious negative numbers for precipitation and humidity.  Will cause
523      some small numerical differences for integrations using pkg/exf/exf_interp.F.
524    o pkg/ctrl/
525      * Add ctrlvec diagnostics in pack/unpack for nondimensional I/O
526        May be enabled via doPackDiag
527      *  introduce z-scaling of
528         + gradient (doZscalePack) and
529         + control (doZscaleUnpack)
530    o pkg/mdsio/
531      * enable useSingleCpuIO for state estimation (ctrl_pack/unpack) mdsio_gl.F
532      * N.B.: leave tiled I/O for tapelev (i.e. mds...vector)
533    
534    checkpoint57b_post
535    o simplify options in diagnostics_fill arguments (remove weird combinations)
536    o fix MNC coordinate variables so that they now contain per-face index
537      values (instead of xC,xG,yC,yG values) when run with EXCH2 since, in
538      general, EXCH2 grids are only aligned to a "local" coordinate system
539    o test diagnostics pkg in dic_example (no output) and ideal_2D_oce (with ouput)
540    o Implement instantaneous output within pkg diagnostics:
541      setting a negative frequency in data.diagnostics produces
542     "snap-shot" output (as opposed to time-average if freq > 0)
543    o move out off EQUIVALENCE all diagnostics that fizhi does not use ;
544      NOTE: change ptracer diagnostics name: use 2 characters to work with
545            more than 9 tracers. Add also diagnostics of advect & diffus flux.
546    o more CF compliance: convert all MNC 'iter' variables to 'T' so that it
547      becomes the coordinate variable for the 'T' dimension
548    o add CF-style coordinate variables to MNC
549      - just a first cut:  numbers are meaningless on the cubesphere and
550        missing along the T axis but otherwise it works!
551    o add surface flux diagnostics: TAUX, TAUY, TFLUX, TRELAX, TICE, SFLUX, SRELAX
552    o pkg/thSIce: read initial state from 6 files ; allow monitor to use MNC.
553    o add diagnostics of advective & diffusive flux for T & S (pTracers coming soon)
554      this is based directly on what the model compute, so that the content of
555      each diagnostics might be affected by switching options (e.g., implicitDiffusion)
556    o small changes for diagnostics (gad_biharm_?.F, arguments of S/R impldiff.F)
557    o clean up build options files for SunOS, in particular
558      - remove -traditional from xmakedepend
559      - change -xarch=v9 to -xarch=native for f77
560      - restore use of make (not gmake)
561      - add CC=gcc if using g77
562    o changes per discussion of AM, JMC, & EH3 today:
563      - move redundant "grid" variables out of "state" -- in preparation of
564        creating proper CF-style coordinate variables and in recognition
565        that any/all grid variables can be easily copied (eg. w/NCO) from
566        the grid files into any of the other NetCDF files
567      - *always* output grid variables with MDSIO (this will eventually be
568        changed)
569      - output MNC grid file if useMNC is true
570    o every instance of _END_MASTER() has been found and replaced with
571      _END_MASTER( myThid ) in order to satisfy certain picky Sun
572      preprocessors
573    o re-arrange diagnostics pkg initialisation:
574     - allow each package to extend the available diagnostics list
575     - add some checking and fix small problems (multi-threaded, ...)
576     - new S/R diagnostics_fill (replace fill_diagnostics):
577       look through the short list of active diag. (instead of the long list)
578       create function DIAGNOSTICS_IS_ON to tell if a diagnostics is active
579    
580    checkpoint57a_post
581    o this set of changes restores TAMC compatibility
582      tested for global_ocean.90x40x15 adjoint on trough
583      (what a pain)
584    
585    checkpoint57a_pre
586    o some modifs in tools/build_options for sunos
587    o call ctrl_pack for ctrl at end for optimcycle=0
588    
589    checkpoint57
590    o add horizontal bi-harmonic viscosity for vertical velocity
591      - new parameter viscA4W (defaults to viscA4)
592      - affects only non-hydrostatic code
593      - to be done: no-slip lateral boundary conditions
594    o switch back to "sflux = sflux - runoff" in exf_getforcing.F
595    o implement Implicit Vertical advection for pTracers
596    o depth convergence accelerator: replace deltaTtracer by dTtracerLev(k)
597      (implemented also for implicit vertical diffusion & advection)
598    o OBCS: extend application of tracer open boundary conditions
599      to a strip beyond the boundary of width Olx/Oly
600    o add call monitor to TAF set of required calls (flow directives)
601      and include in natl_box_adjoint
602    o untangle a few ifdefs related to cost, ctrl, autodiff
603      untangel a few ALLOW_ECCO_OPTIMIZATION
604    o Apply Cooper & Haines representative estimates also at sub-surface (k=Nr)
605      (theta2, salt2 in ecco_cost_weights)
606    
607    checkpoint56c_post
608    o OBCS as control variables
609      - update ctrl_ad_diff.list, obcs_ad_diff.list
610      - remove balance of obcs controls from default
611      - fix index bug nobcs in ctrl_init
612      - fix dummy fields filen in ctrl_pack
613      - add dummy weights for obcs
614    o lsopt: comment out fort.94 output
615    o optim:
616      - remove unnecessary header files
617      - adjusted namelists
618      - add xerbla.F to Makefile
619    o exf:
620      - multiple modifications of exf_check_range
621      - unit change in exf_init_runoff from [m/year] to [m/s]
622    o mdsio:
623      - i/o-vector change debugLevel from debLevA to debLevB
624    
625    checkpoint56b_post
626    o collect all ptracers output in an new routine (PTRACERS_OUTPUT) that
627      is called from DO_THE_MODEL_IO
628      - rename PTRACERS_STATV_WRITE to PTRACERS_WRITE_TIMEAVE
629      - introduce new parameter PTRACERS_dumpFreq (defaults to dumpFreq)
630      - clean up PTRACERS_WRITE_TIMEAVE a little
631    o add another verification experiment that tests both the cfc-pkg and
632      the gchem-pkg with GCHEM_SEPARATE_FORCING undefined, that is with
633      reactive tendencies treated inline with regular timestepping
634    o testreport previously did a lousy job of comparing small numbers, so
635      we (Ed and Martin) changed the  way the cut-off of 1.e-12 is
636      implemented in the little c-progam tmp_cmpnum.c which is embedded in
637      testreport.
638    o ptracers_monitor: bug fix for MPI
639    
640    checkpoint56a_post
641    o GCHEM: finish reorganizating the package
642      - forward_step calls GCHEM_CALC_TENDENDY, which computes gchemTendency
643        (introduces another 3D-array for each passive tracer, but only if
644        GCHEM_SEPARATE_FORCING is undefined. For GCHEM_SEPARATE_FORCING
645        gchemTendency is not needed because the timestep is done separately)
646      - gchemTendency is added to gPtr in GCHEM_ADD_TENDENCY
647      - GCHEM is now---more or less cleanly---separate from PTRACERS
648      - to bo done: handling of surfaceForcingPtr that is needed for KPP not
649        so clear to me how that should be done in a general way.
650    o CFC: improve formatting of output in CFC_ATMOS
651    o PTRACERS:
652      - rename GCHEM_MONITOR to PTRACERS_MONITOR and call it from MONITOR, so
653        that ALL experiments with ptracers enable can be checked. This makes
654        GCHEM_MONITOR obsolete.
655      - include a runtime parameter PTRACERS_monitorFreq that defaults to
656        monitorFreq
657      - set default PTRACERS_write_mdsio to false if PTRACERS_write_mnc is true
658    o add PTRACERS (PTR0[1-5]) to testreport output
659    o exf_check_range:
660      * default changed to .TRUE.
661      * will check values for niter0 if debLevA, every timestep if debLevB
662      * STOP in exf_check_range if 'out of range'
663      * range chosen generous to allow for potential extema
664      TBD: a version with stricter range
665           permitted range would be runtime parameters
666    o GMredi:
667      - fix ldd97 slope limit ; extend valid domain of Psi-Bolus ;
668      - change S/R GRAD_SIGMA to be valid in the overlap on CS-grid.
669      - change the default GMREDI_OPTIONS.h: compile everything except Visbeck
670    o GCHEM:
671      - move call to GCHEM_FORCING_SEP, so that it is now called before
672        the blocking exchanges to avoid computing halos in GCHEM_FORCING_SEP
673      - introduced a useGCHEM runtime flag and applied it everywhere.
674      - renamed PTRACERS_SEPARATE_FORCING to GCHEM_SEPARATE_FORCING;
675        this flag is now only visible within GCHEM-pkg routines.
676      - moved gchem_forcing_int temporarily into ptracers_forcing, this will
677        be replaced by a 3D array that is computed before thermodynamics; for
678        this, the tracer ID iTracer had to be included into the parameter list
679        of ptracers_forcing
680      - set up forward_step to call gchem_forcing, that will replace
681        gchem_forcing_int in ptracers_forcing
682      - cleaning up
683    o small cleaning of exch2: remove files that are also in eesupp/src
684    
685    checkpoint56
686    o AIM: read land-Fraction earlier (from ini-fixed) and monitor land at nIter0
687    o mnc: cleanup "full" files--fixes out-of-memory problem
688    o ECCO-GODAE
689      * model/, pkg/, code/, input/ now complete w.r.t. ECCO-GODAE production setup
690      * fully merged and updated from SIO code
691        windstress sign change affects
692        - exf_inscal_[u/v]stress
693        - sign of xx_tau[u/v] adjustments
694        - signs in cost_scat
695      * ctrl_get_gen: avoid update of tau[u/v] for first few days
696      * natl_box_adjoint updated and compressed
697      * 2-level checkpoint switch added
698        (tested in EXP. 1 of natl_box_adjoint)
699      * new switch doInitXX to avoid init. of xx_... in optimcycle=0
700    o SVD
701      * first complete, non-hacked version for SVD calculations
702      * all interfaces clean w.r.t to handling of xx_..., adxx_..., g_xx_...
703        performed via direct access files admtlm_vector.it????
704        (via ctrl_[un]pack)
705      * optimcycle is used for ARPACK iteration counter
706        (note: adxx_... is iterated, rather than xx_...; latter is constant!)
707      * EV problem ok w.r.t. L2-norm in tangent space; need to check other norms
708        and add linear transforms where necessary
709      * controls are initial/final SST, SSS (can be extended; need to check
710        ctrl_set_[un]pack_xyz.F according to ctrl_set_[un]pack_xy.F
711    o mdsio: filename info to both stderr, stdout
712    o exf: exf_inscal_runoff: separated default conversion [m/year] -> [m/sec]
713      from sign change
714    
715    checkpoint55j_post
716    o isolate dissipation tendency (allow to keep it out off AB) in V.I form.
717      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
718    o add consistent build directories and .cvsignore files to verification
719    o added viscA4GridMin and viscA4GridMax for more control on biharmonic viscosity
720    o make all subroutines 30 or less characters in length for certain older
721      compilers to work (a thorough search only turns up two routines in
722      pkg/ptracers)
723    o allow (vecinv only) a different horiz. viscosity for Divergence and Vorticity;
724      affects (truncation level) output.txt of global_ocean.cs32x15(&.thsice)
725    
726    checkpoint55i_post
727    o change arrays for total vertical diffusivity (2.D if explicit,
728      3.D if implicit) ; each ptracer uses its own background value.
729    o added mnc/NetCDF output capability to ocn_compon_interf
730      - added bits to verification/cpl_aim+ocn so that it can run on
731        ITRDA and other clusters without the mpirun "-wd" option
732    o fixed wayward endif in mom_fluxform.F that messed up cyclindrical
733      configuration
734    o give MNC the ability to create additional files rather than
735      exceeding a specified file size limit "MNC_MAX_FILESIZE"
736      - the default is just less than 2GB which is a practical limit
737        on many systems
738    o Compute the non-local term using either KPP vertical diffusivity (=default)
739       or the total vertical diffusivity (when KPP_ghatUseTotalDiffus=T)
740    
741    checkpoint55h_post
742    o add verification test "vermix"
743    o remove all the *_ioinc flags and replace with the single global
744      outputTypesInclusive flag
745    o allow to set a vertical profile of vertical diffusivity for T & S
746    o call PACKAGE_BOOT & PACKAGES_READPARMS just after INI_PARMS
747    o useMNC moved from data.mnc to data.pkg
748    
749    checkpoint55g_post
750    o Renaming carbon AD experiments to comply with testreport conventions
751    o Updating adjoint of Held-Suarez hs94.1x64x5
752    o Fixing directives for non-ECCO forward_step, after ECCO directives
753      have been fixed to avoid recomp. of do_oceanic_phys
754      Works well for global_ocean.90x40x15,
755      but recomp. issue remains for carbon
756    o Updating adjoint output for natl_box_adjoint after
757      pkg/ecco has been modified (see taga c55d_post)
758    
759    checkpoint55f_post
760    o rename to timeave_init_fixed
761    
762    checkpoint55e_post
763    o some delicate re-shuffle of store directives to avoid one
764      extra call of do_oceanic_physics
765      affects ecco_the_main_loop.F, do_oceanic_physics.F
766      checkpoint_lev1_directives.h
767    o NB: this may break global_ocean adjoint temporarily,
768      but it is clear how to fix it. Will do later, need this now.
769    
770    checkpoint55d_post
771    o ECCO specific cost function terms (up-to-date with 1x1 runs)
772    o ecco_cost_weights is modified to 1x1 runs
773    o modifs to allow observations to be read in as
774      single file or yearly files
775    o enable to read exf forcing fields as either
776      single file or yearly files (flag useExfYearlyFields)
777    checkpoint55d_pre
778    
779    o switch between 2-level and 3-level checkpointing
780    o add ability of MNC to write local and "partial" (eg. 2D slices where
781      the full 3D field is never actually stored) arrays to NetCDF files
782      with the correct (that is, the complete multi-dimensional) set of
783      array indicies
784      - used in mom_vecinv() to write the diagFreq output
785      - tested (demonstrated) in verification/aim.5l_cs
786    o further mnc-ification
787      - add verification/lab_sea to the list with mnc setups
788      - fix undefined mnc v-names in cd_code
789      - add kpp to mnc output (both snapshot and timeave)
790    o non-hydrostatic code
791      - added horizontal viscosity parameter viscAhW for w, that replaces viscAh
792        in calc_gw.F
793      - defaults to viscAh
794      - this is useful, when I want to use viscAh=0 (e.g., only biharmonic
795        friction or Leith) in non-hydrostatic mode, as long as there is
796        no biharmonic friction and/or Leigth or equivalent for vertical velocity.
797    o pkg/cost
798      extend simple cost functions to treat time mean quantities
799      (T,U,V) via cost_accumulate_state from cost_tile
800    o multidimAdvection on CS-grid: implement the full 3 pass ; overlap needs to
801        be 2 times larger than the minimum size the advection scheme requires.
802        now get a perfect conservation of salt in advect_cs test-exp (updated)
803    o GGL90 (Gaspar's TKE mixed layer)
804      - add horizontal diffusion of TKE, requires exchanges in
805        do_fields_blocking_exchanges, horizontal diffusivity is zero by
806        default. In OPA there is no horizontal diffusion of TKE but the
807        mixing coefficients are computed from a horizontal average of TKE of
808        6 points or so. I think that diffusion has a little more physical
809        justification.
810      - clean up ggl90_calc in the hope of reducing memory usage (this hope
811        was in vain)
812      - mask tke-variable in ggl90_init
813    o fix mask Pb in multidimAdvection on CS-grid (still a small Pb with ipass)
814    o fix biharmonic diffusion on CS-grid.
815    o more obcs stuff
816      - added obcs_external_fields_load as an alternative to the EXF-pkg option
817        for reading boundary values. This routine is called from
818        obcs_prescribe_read
819      - updated obcs_check
820      - changed sponge layer relaxation parameter units for days to seconds
821      - turned off sponge layer by default
822      - changed argument list of OBCS_CALC to myTime+deltaTclock
823      - fixed about 35 bugs in obcs_external_fields_load
824    
825    checkpoint55c_post
826    o obcs stuff
827      - new runtime flags useOBCSprescribe, useOBCSbalance
828      - re-arranged obcs_calc
829      - moved exf_getobcs to obcs_prescibe_read
830        obcs_prescibe_read is called after ORLANSKI stuff
831        and independent of it (executable can contain all).
832      - updated obcs_check
833      - added exchanges for U,V,gU,gV for useOBCSprescribe=.TRUE.
834        These may be necessary only if tangential velocities are
835        prescribed at OB, not sure, needs testing.
836    o make the MNC_CW_ADD_VATTR_* subroutines all take scalar arguments
837      which simplifies the calls and passes the ifc check-bounds test
838    
839    checkpoint55b_post
840    o add a 2D scalar, Z location, exchange_2 routine.
841    o EXCH_UV for CS-grid: add one u,v in the corner-halo region, allows
842      to compute vorticity on a wider stencil [e.g., vort3(0,1)&(1,0)]
843      affects advect_cs results (for the wrong reason): update output.txt
844    o use a more standard discretization for biharmonic viscosity ;
845     (original version still available with #define MOM_VI_ORIGINAL_VISCA4 )
846      affects results of dome set-up: update output.txt
847    o fix gad_advection.F (CubedSphere part), back to version 1.23
848    o fix bug in mom_vi_del2uv.F (CubedSphere part).
849    
850    checkpoint55a_post
851    o merged code to
852      * prescribe/read time-dependent open boundaries
853        (works in conjunction with exf, cal)
854      * sponge layer code for open boundaries
855      * each boundary N/S/E/W now has its own CPP option
856        (healthy for the adjoint)
857    
858    checkpoint55
859    o up-to-date adjoint of previous breaks
860      - natl_box_adjoint: problem for exp 12, 13: cost = 0. needs fix
861      - global_ocean_ebm: adjoint still needs fix (TLM ok)
862      - global_ocean.90x40x15: extended GMREDI_OPTIONS.h
863      - carbon: * remove tr1-related adjoint verification
864                * add ptracer as control variable
865    o remove all tr1-related code (ALLOW_PASSIVE_TRACER)
866      (adjoint stuff still has some tr1 'names', but all use ptracer arrays)
867    
868    checkpoint54f_post
869    o in verification/carbin/ remove experiment related to
870      ALLOW_PASSIVE_TRACER (array tr1 etc)
871      code_ad/ input_ad/ results_ad
872    
873    o add two new packages
874      - ggl90, TKE-model of Gaspar et al. (1990), Blanke+Delecluse (1993)
875        + subject to optimization (memory)
876      - opps, OPPS (ocean penetrative plume scheme) of Paluszkiewicz+Romea (1997)
877        + subject to reordering (many GOTOs in the original code)
878        + so far opps is called for every (i,j) point, and then operates in
879          the vertical; one may want to reorder the scheme in order operate in
880          horizontal slabs at the cost of (a lot of) memory, at least ten new 3D
881          fields)
882    o overhaul of IO so that we now have flags for MDSIO and/or MNC
883      - all verification tests compile and run with linux_ia32_g77
884      - defaults are compatible with current input files--nothing
885        should change if you were not previously using MNC
886      - MNC output has been added in numerous places (eg. timeave)
887        but there are still a few writes not yet do-able with MNC
888        (this is in progress)
889      - flags now allow for either/or/both use of MDSIO and MNC and
890        documentation will soon follow
891      - numerous small formatting cleanups for ProTeX
892    o add version info (via BUILD_INFO.h) to MNC and stdout
893    
894    checkpoint54e_post
895    o add two new packages
896      - pp81 (Packanowski and Philander, 1981), Richardson number and
897        stratification dependent mixing
898      - my82 (Mellor and Yamada, 1982) level 2 turbulence closure scheme
899      - these scheme operate in a similar manner as KPP (without ghat, of
900        course), however there is only one diffusivity that is used for both
901        temperature and salinity (and passive tracers)ç
902    o add offline package
903    o add "verification/dic_example" which contains a dic-gchem-ptracer setup
904      provided by Stephanie Dutkiewicz
905    o genmake2: add ability to search for C compilers and cleanup test output
906      - fixes recent SX-6 problems and should help with others (eg. HP-UX)
907    
908    checkpoint54d_post
909    o data.diagnostics: if levels() is unspecified then ALL levels are diagnosed
910    o bug fix in pkg/cal/cal_addtime.F for TheCalendar='model' day count is wrong,
911      leading to additional shift by 5 days each year of integration
912       (i.e. leading to considerable offset over the years)
913    o update global_ocean.cs32x15/thsice: use z* + RealFW + staggerTimeStep
914    o start with no AB and no initial filtering (staggerTimeStep):
915      change the results of test-exp: hs94.128x64x5, hs94.1x64x5 & hs94.cs-32x32x5
916    o move ocean specific S/R calls from forward_step.F to do_oceanic_phys.F
917      (external loading & cpl import/export stay in forward_step.F)
918    o update coupling interface to work with new staggerTimeStep
919    o change MDSIO ptracers_pickup.
920    o fix a bug in Flux deriv. vs Ts (pkg/aim_v23/phy_suflux_sice.F);
921    o genmake2 fixes so netcdf now works on halem ("osf1_alpha_*")
922    o bugs fixed in kpp_calc.F (ustarY) and external_forcing.F (Qsw & Partial-cell)
923    
924    checkpoint54c_post
925    o replace surfaceTendency U,V,S,T,Tice,Ptr by surfaceForcing U,V,S,T,Tice,Ptr
926      this affects (truncation error) output.txt of test-exp:
927       global_ocean_ebm,_pressure,.cs32x15(&.thsice), lab_sea & natl_box
928    o pkg/kpp: replace pMask by maskC to reduce memory size (one 3.D array)
929    o change Qnet to always be the net heat flux, (+upward).
930      affects (truncation error) output of natl_box exp.: updated
931    o define the max number of passive tracers in PTRACERS_SIZE.h
932    o start to test mnc routinely in exp0
933    o add sea-ice loading (sIceLoad) as a new forcing field.
934    
935    checkpoint54b_post
936    o add testreport "-j JOBS" option for parallel builds (tested and pretty
937       impressive on Altix and Opteron systems)
938    o diagnostics can now write NetCDF files through the mnc package
939    o staggerTimeStep & NLFS: update pkg aim_v23 & thsice; update aim.5l_cs output
940    o staggerTimeStep & multi-Dim-Advec: Exch(U,V) added
941    o staggerTimeStep & NLFS: rescale T & S surface tendencies.
942      affects (truncation error) output of lab_sea & natl_box exp.: updated
943    o change pickup _cd & _ptracers (old pickup restart: usePickupBeforeC54=.T.)
944    
945    checkpoint54a_post
946    o re-write staggerTimeStep: step fwd U,V and then T,S (reverse the order).
947    o change pickup file (to restart from old pickup, set usePickupBeforeC54=.T.)
948    o get a perfect restart when using RealFreshWaterFlux + NLFS (not finished)
949    o update output of all exp. that use staggerTimeStep (except hs94.cs & 2D)
950      + internal_wave (shift in writing cg2d_ini_res)
951    checkpoint54a_pre
952    
953    o require forcing_In_AB=.FALSE. and remove surfaceTendencyTice from pkg/seaice
954      - modified verification/lab_sea and natl_box_adjoint accordingly
955    
956    checkpoint54
957    checkpoint53g_post
958    o prepare splitting of thermodynamics: store convect.counter in common block
959    o store d.etaH/dt (instead of Div.hV) in common ; affects (truncation error)
960      output of: global_ocean.cs32x15, global_ocean_pressure & internal_wave
961    o cnh's modifs to gad_advection.F for cube-sphere multi-dim advection
962    o new parameter "nShapS": allow to treat differently S from T (nShapT)
963    o separate Vert.Advec.Scheme from horizontal Advec.Scheme (T & S)
964    o restore adjointability
965    
966    checkpoint53f_post
967    o modifications that affect AIM experiment results (update output.txt):
968      - no advection of S at top interface Nr (pkg/generic_advdiff)
969      - air surf. temp: use lower value between T0 & T1 (phy_suflux_prep.F)
970    o AIM pkg:
971      - include stability function into surf.Flux derivative relative to Tsurf
972      - calculate clear-sky radiation & surface temp. change (for diagnostics)
973    
974    checkpoint53e_post
975    o merged cylindrical coord configuration
976    o added rotating_tank experiment
977    checkpoint53e_pre
978    
979    checkpoint53d_post
980    o faulks upgraded: re-generate output.txt that have changed:
981       global_ocean.cs32x15(.thsice), global_ocean_ebm, lab_sea, natl_box
982    o Added Bryan and Lewis, 1979, vertical diffusivity profile
983    o pkg/land: fix problem in land_impl_temp.F when Ts arround freezing.
984    o added Sadourny discretization of Coriolis
985      - moved some PARAMETERS from mom_*_coriolis.F to PARAMS.h
986      - re-enabled use of omega3 (useAbsVorticity)
987    o added Leith (Phys. Fluids, 1968, 10, 1409-1416) variable viscosity for
988      vector-invariant equations
989      - note: does *NOT* yet use same variable visc. for no-slip BC's.
990    o recoded the lateral boundary conditions for non-hydrostatic w, this time
991      hopefully without new bugs
992      - still to do: biharmonic friction for non-hydrostatic w
993    o bug fix for mom_*_sidedrag: rA -> rAs,rAw
994    o regenerated output for global_ocean_ebm (using -ieee)
995    o fix mom_common/mom_*_sidedrag.F to recover numeric output prior to creation
996      of mom_common/
997      - simple re-arrangement of instructions within computing loop
998    checkpoint53d_pre
999    
1000    checkpoint53c_post
1001    o new version of coupler for AIM+thSIce and Ocean models
1002     - new fields (SSS,h_MixLayer ...) are exchanged through the coupler
1003     - land: change Evaporation of snow
1004     - aim with thSIce: fix bug in snow-precip.
1005    o changes to calc_gw.F
1006     - bug fix for w^2 term near the bottom boundary
1007     - (hopefully) improve the lateral slip boundary condtions for use with
1008        partial/looped cells
1009      - because the bug fix changes two verification experiments anyway (exp5
1010        and plume on slope), change the lateral boundary condition from half slip
1011        to the value of no_slip_sides
1012    o ebm package wasnt quite up to the parallel task. Fixed that.
1013    o Adjoint of EBM package + verification
1014      * TLM OK
1015      * ADM not sufficient accuracy yet (needs further testing)
1016    
1017    checkpoint53b_post
1018    o Commiting new energy balance model to repository
1019      * package is pkg/ebm
1020      * verif. is verification/global_ocean_ebm
1021      * references are in ebm_driver.F
1022    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1023    C        Global thermohaline circulation. Part I:
1024    C        Sensitivity to atmospheric moisture transport.
1025    C        J. Climate 12(1), 71-82
1026    C      * X. Wang, P. Stone and J. Marotzke, 1999:
1027    C        Global thermohaline circulation. Part II:
1028    C        Sensitivity with interactive transport.
1029    C        J. Climate 12(1), 83-91
1030    C      * M. Nakamura, P. Stone and J. Marotzke, 1994:
1031    C        Destabilization of the thermohaline circulation
1032    C        by atmospheric eddy transports.
1033    C        J. Climate 7(12), 1870-1882
1034    o Will need long integration testing.
1035    checkpoint53b_pre
1036    
1037    o created pkg/mom_common in preparation for variable viscosity code
1038    o renamed and split ini_mnc_io
1039    o pkg/land: only liquid water can diffuse or run-off
1040    o AIM using land: soil wetness availability account for snow
1041    o added printMapIncludesZeros to EEPARMS namelist
1042    
1043    checkpoint53a_post
1044    o restore TAMC compatiility for exf_constants.h
1045      (no usage of _d in .h)
1046    o Additional storing in KPP in an attempt to fix
1047      TAMC problem with adjoint of KPP code.
1048      (no success...)
1049      Identical code works fine with TAF.
1050    o Fixed verification/natl_box_adjoint experiments.
1051      Initial conditions for Experiments 4 and 5 are now
1052      set to "SEAICE_initialHEFF=0", which is more reasonable,
1053      and hence gives results closer to that of Experiment 2.
1054      Experiment 6 requires "SEAICE_initialHEFF=1" and is working once again.
1055    
1056    checkpoint53
1057    o stable checkpoint with up to date adjoint
1058      TLM tests only run for 1st grdchk at the moment. Its unclear if
1059      this is a code problem or a problem with resetting code for g_
1060      variables that is being autogenerated wrong.
1061      Otherwise:
1062       o code is testing well on Linux (P4 and AMD), SGI Alitix and Irix.
1063       o IBM and HPQ tests could not be run because NCAR (IBM) and NCCS (HPQ)
1064         are both still in chaos following their security messes.
1065    
1066    checkpoint52n_post
1067    o various build (mostly genmake2) changes including:
1068      - ability to build/run more easily within Cygwin and MacOS X
1069      - more complicated Makefiles with a stronger dependence on Gnu Make
1070    o pkg/seaice modifications
1071      - added SEAICE_deltaTtherm and SEAICE_deltaTdyn in order to reduce cost
1072        of pkg/seaice.  For time being, SEAICE_deltaTtherm = deltaTtracer
1073        and SEAICE_deltaTdyn must be integer multiple of SEAICE_deltaTtherm
1074      - changed proxy for geostrophic velocity and updated
1075        verification/lab_sea/results/* accordingly
1076      - removed ADI dynamic solver from pkg/seaice
1077      - replaced all occurrences of 1/CSTICE or 1/CSUICE
1078        they caused a segmentation fault under certain circumstances
1079      - removed unused field WATR
1080    o bug fix in exf-package:
1081      -  u/vwind are defined at tracer/pressure points. The values of u/vwindmask
1082         now reflect that.
1083    o small fixes in the cal-package:
1084      - set reference date to first of January for the 'model'-calendar
1085      - failing of cal_CheckDate in cal_FullDate now actually results in a
1086        warning
1087    o small modifications in exf-package to increase flexibility:
1088      - change climtempfreeze from a constant to a runtime parameter that
1089        is specified in data.exf_clim (default = -1.9)
1090      - introduce runtime parameter windstressmax (default = 2.0) that is
1091        specified in data.exf
1092    o fix in pkg/thsice:
1093      - update Evap (Tsf changes) to be consistent with Latent heat flux
1094      - maintain snow precipitation unchanged (even if Tsf >=0).
1095     both affect global_ocean.cs32x15/(.thsice) results ; update output.txt.thsice
1096    
1097    checkpoint52m_post
1098    o commented out call to cal_GetMonthsRec in swfrac.F and added some comments;
1099      this does not change any of the results, because myIter=0 in swfrac always
1100      lead to jwtype=2 (the default anyway), but the call makes little sense
1101      as a default
1102    o no SHORTWAVE HEATING lost at the bottom; affects lab_sea output; updated
1103    o re-work pkg/thsice interface with ocean & bulk_force pkg to allow
1104      atmospheric model (AIM) to use it ; add a "slab ocean" component.
1105    o pkg/aim_v23 : add interface to call thermodynamic sea-ice (thsice)
1106    o update global_ocean.cs32x15/output (.thsice) after changes in pkg/thsice
1107    o extending useSingleCpuIO option to work with new exch2 I/O format
1108      - old-style, missing-tile I/O is still accessible by defining CPP
1109        option MISSING_TILE_IO in pkg/mdsio/MDSIO_OPTIONS.h
1110    o monitor package can write to NetCDF files and/or STDOUT
1111    o fix re-definition bug in MNC_GRID_INIT_ALL()
1112    o doc/api_reference added
1113      - a framework for building an API Reference Manual using all
1114        the "protex" comments embedded in the code
1115      - see pkg/generic_advdiff, pkg/mnc for examples
1116    o MNC:

1160    o paramter list of CALL ADTHE_MAIN_LOOP
1161    o added initial do_the_model_io to ecco
1162    o set all ...Freq to zero after cost_final

1166    checkpoint52j_post
1167    o fix nchklev in tamc.h for global_ocean...
1168    o Bringing flow and store directives up-to-date
1169    o Really weird thing!
1170      call do_the_model_io from the_main_loop with parameters
1171      starttime, niter0, instead of mytime, myiter, screws up the adjoint:
1172      TAF places a faulty re-call of initialise_varia
1173      after cost_final call which should not be there!
1174    checkpoint52j_pre
1175    
1176    o tweaked pkg/mdsio/mdsio_readfield.F to have more useful logic and
1177      error messages

1208      there is no sea-ice on cube faces 1, 2, 4, and 5.
1209    
1210    checkpoint52f_post
1211    o added exch2 cube routines to pkg/exch2

1218      for now, only implemented with Lax-Wendroff (tracer) and VectInv (mom)
1219    o step.1 : rewrite (as in MultiDimAdvec) explicit tracer stepping (gad_calc_rhs.F)
1220      to work with implicit vertical advection and AB ;
1221    o Implic. vert. advect. implemented with flux-limiter, c2, u3 and c4 scheme.
1222    o update output (gad_calc_rhs.F changes affect truncation error) of exp:
1223     front_relax, global_ocean .cs32x15 & _pressure, internal_wave, lab_sea, natl_box
1224    checkpoint52e_pre
1225    
1226    o fix bug in impldiff when Nr=1 or Nr=2.
1227    o change the albedo in pkg/thsice (as GISS model); update output_thsice.txt
1228    o little changes (fftpack, aim/phy_suflux ...) to pass the "checkbounds" test.
1229    o fix deltaTfreesurf in update_cg2d.F (left from c45d_post): affects 2
1230      ocean exp. that use NLFS: global_ocean.cs32x15 & global_ocean_pressure
1231    o added exf_offset_atemp for Celsius to Kelvin conversion of atemp
1232    o eesupp/inc/EEPARAMS.h: MAX_NO_PROCS=1024
1233    o pkg/cal/cal_toseconds.F fix for long (>60 years) integrations
1234    
1235    checkpoint52d_post
1236    o re-tiled many expts to allow comparison in multi-processor mode
1237      - updated output accordingly
1238      - changed hs94.128x64x5 to use intial T from file rather than use the

1244      - added "#undef ALLOW_USE_MPI" support to eesupp/src/scatter_2d.F
1245      - added pkg/exf/exf_set_uv.F for on-the-fly interpolation and rotation
1246        of surface winds for the cube
1247      (A verification experiment, based on global_ocean.cs32x15, but with
1248       pkg/seaice turned on and with on-the-fly interpolation from the NCEP
1249       Gaussian grid is described in MITgcm_contrib/high_res_cube/README_ice,
1250       complete with example surface forcing files and matlab scripts to look
1251       at the output and compare it with that of global_ocean.cs32x15.)
1252    o packages pickup: $PKG_write_pickup called from packages_write_pickup ;
1253       but call to $PKG_read_pickup remains in $PKG_ini_vars: change CD_code
1254       to conform to the common rule.
1255    o check-in the first version of the coupler + interfaces for multi-components
1256       set-up (Chris's version, adapted to work on cubed-sphere grid); use MPI.
1257       - imply modification in eesupp (MPI_COMM_MODEL < MPI_COMM_WORLD).
1258       - atmosphere: use pkg aim_v23 ; no sea-ice for now.
1259       - ocean and atmos. share the same horizontal grid (no interpolation).
1260       - exchanges between component and coupler is done in forward_step
1261    o new verification experiment, cpl_aim+ocn:
1262       coupled ocean - AIM atmosphere on cs32 grid.
1263    
1264    checkpoint52d_pre
1265    o surface flux time-av diagnostic modified for NLFS & RealFreshWater
1266    o add call to AIM pendant S/R in external_forcing & external_fields_load.F
1267    
1268    checkpoint52c_post
1269    o Fixing OPTIONS files for use of exf:
1270      - ALLOW_ECCO not needed
1271      - ECCO_CPPOPTIONS.h should not be included from
1272        EXF_OPTIONS.h/CAL_OPTIONS.h, but from CPP_OPTIONS.h
1273        as has been the case in the past
1274      - All cal/exf related options are currently set in
1275        single header file. Should remain so until we
1276        agree on a consistent new policy.
1277    o Removed all CPP options for cal package.
1278      cal has no more CPP options.
1279    o modified STOREs in GAD_ADVECTION
1280    o corrected key comp. for passkey
1281    
1282    checkpoint52b_post
1283    o new version: "thsice" of thermodynamic sea-ice pkg:
1284     - only 1 call from "forward_step"; conserve energy, fresh-water & salt.
1285     - modify fluxes but do not change theta directly;
1286     - light cleaning of bulk_force pkg (still needed with thsice).
1287     - add forcing fields + data files in global_ocean.cs32x15/inp_thsice
1288       + output_thsice.txt to test thsice & bulk_force pkgs.
1289    o put back grid & coriolis monitor output.
1290    checkpoint52b_pre
1291    
1292    o call "do_the_model_io" at the beginning (=> dump initial state)
1293    o use rhoConstFresh to define convertEmP2rUnit (was done only in ocean-P)
1294    o sort out interplay between tamc.h and PTRACERS_OPTIONS.h
1295      (need info on NUMBER_OF_PTRACERS)
1296    o missing PTRACERS headers in some routines
1297    o default tamc.h in pkg/autodiff supposed to crash
1298      to ensure proper customization
1299    
1300    checkpoint52a_post
1301    o modifications to make FREEZE (_SURFACE) flux visible to pkg/kpp
1302      - moved surfaceTendencyTice from pkg/seaice to main code
1303      - subroutine FREEZE_SURFACE now limits only surface temperature
1304        and is called in FORWARD_STEP (if allowFreezing=.TRUE.)
1305        => new output.txt for global_ocean.cs32x15 & global_with_exf
1306      - keep the old version of FREEZE for backward compatibility;
1307        global_ocean.90x40x15 left unchanged using useOldFreezing=.TRUE.
1308      - corresponding modifs for TAF directives
1309    o added surface flux output variables to TIMEAVE_STATVARS

1313      but no warning issued by TAF
1314    
1315    checkpoint52a_pre
1316    o some bug fixes for #undef REAL4_IS_SLOW
1317    
1318    checkpoint52 = ecco_c52_e35
1319    o after testing adjoints of checkpoint51u_post
1320    
1321    checkpoint51u_post
1322    o this is the post-merge tag of the ecco-branch
1323      (needs another clean checkout and re-testing)
1324    o various natl_box_adjoint configs and results
1325      but no input fields
1326    o obcs adjoint not yet merged!
1327    o adding ECCO global 1x1 and 2x2 degree configs
1328    o updated/extended some store directives for seaice
1329    o pkg/ecco now containes ecco-specific part of cost function

1333      (new namelist ecco_cost_nml)
1334    o in ctrl/ cleaned some cross-dependencies and updated CPP options
1335    
1336    checkpoint51t_post
1337    o this is the pre-merge tag of the ecco-branch
1338    
1339    checkpoint51s_post
1340    o cleanup: removed various obsolete #define-s
1341    o pkg/grdchk
1342      - renamed 'ph-grd 3' to 'grad-res'
1343      - merged from ecco-branch
1344        (remaining bug fixes for obcs gradient checks)
1345      - additional high-precision output for testreport
1346        (grep for 'precision_grdchk_result')
1347    
1348    checkpoint51r_post
1349    o cleaned up or removed CPP_OPTIONS.h files
1350    o updated results for some of the tests to reflect the new
1351      optfiles (-ieee: -O0 instead of -O3)
1352    
1353    checkpoint51q_post
1354    o cd_code:
1355      - moved cd_scheme.F -> cd_code_scheme.F
1356      - separate read_checkpoint from cd_code_ini_vars.F
1357      - separated cd_code part from write_checkpoint
1358      - updated AD_SOURCE, generated .flow
1359      - added CD_CODE_VARS.h to the_main_loop
1360      - Moving cd_code specific store dir.s to pkg/cd_code
1361    o ctrl package totally restructured
1362      - pack/unpack now optional and decoupled from
1363        xx_/adxx_ I/O
1364      - ctrl_pack/unpack cleaned
1365        (new routines ctrl_init_ctrlvar.F, pkg/ctrl/ctrl_init_wet.F)
1366      - confined inclusion of AD_CONFIG.h to where necessary.
1367    o genmake2: changed AD dependencies from SRCFILES to AD_FILES
1368    
1369    checkpoint51p_post
1370    o create initial cd_code package
1371      - WARNING: the initialization of fields within packages
1372        is broken because INI_FIELDS (where READ_CHECKPOINT is
1373        called) is called *before* PACKAGES_INIT_VARIABLES.
1374        This seems to be backwards since
1375        1) its important to initially zero the entire field including
1376           the "halo" region
1377        2) zeroing needs to be done *before* reading pickup info
1378           and the pickup call might or might not happen in any
1379           particular run
1380      - this needs an overhaul for R2
1381    o cleanup verification/*/code/GMREDI_OPTIONS.h
1382    o cleanup testreport
1383    
1384    checkpoint51o_post

1415      - moved surfaceTendencyTice from pkg/seaice to main code
1416      - FREEZE & EXTERNAL_FORCING_SURF moved to FORWARD_STEP
1417      - subroutine FREEZE now limits only surface temperature
1418        (this means new output.txt for global_ocean.90x40x15,
1419         global_ocean.cs32x15, and global_with_exf)
1420    o added surface flux output variables to TIMEAVE_STATVARS

1510        "USE_EXF_INTERPOLATION" to pkg/exf.
1511      - This is a temporary Cartesian-grid hack until
1512        the super-duper ESMF coupler becomes available.
1513      - See verification/global_with_exf/README for usage example.
1514      - Removed obsolete EXFwindOnBgrid and SEAICEwindOnCgrid
1515        flags and modified pkg/seaice accordingly.
1516    o Bug fix to pkg/ptracers, pkg/generic_advdiff/gad_calc_rhs.F,
1517        and pkg/kpp/kpp_transport_ptr.F for dealing with tracer
1518        non-local transport term.
1519    
1520    checkpoint51e_post
1521    o pkg/mom_vecinv:
1522      - changes related to hFac: use S/R from aim.5l_cs/code (coriolis & vort.advec)
1523      - add time-ave diagnostic of vorticity advection.
1524    o add diagnostic (instantaneous) of Shapiro Filter effect for T,S & UV.
1525    o atmospheric geopotential: - include water vapor effect;
1526                                - use p^kappa in p* scaling.
1527    o land pkg: read initial state from files.
1528    o AIM : add stratospheric drag in the upper level
1529    
1530    checkpoint51d_post
1531    o change function ILNBLNK (=> last non-blank char.) to return zero
1532      (instead of the string length) when the string. char is empty
1533    o fix bug in dxV,dyU definition of cubed-sphere grid (ini_curvilinear_grid)
1534    o modif's to restore TAMC compatibility
1535      - avoid "_d" constructs in PARAMETER declarations
1536      - avoid interrupting lines by comment lines
1537    o Use cluster local disks for purely local I/O
1538      vs. globally visible disks needed for ctrl stuff
1539      (merged from ecco-branch)
1540      - new active_file_loc... and mdsio_..._loc routines
1541      - affected packages: autodiff, ctrl, grdchk, mdsio
1542    
1543    checkpoint51c_post
1544    o introducing integer flag debugLevel
1545      - debLevZero: suppress all output
1546      - debLevA: standard
1547      - debLevB: equivalent to current debugMode=.TRUE.
1548    o introducing pathname variable mdsioLocalDir for mdsio
1549      that can be specified at runtime
1550      (relevant for cluster I/O to local disk)
1551    `
1552    >>>checkpoint51b_post
1553    adjoint of ptracers
1554    o disentangled ALLOW_PTRACERS using new ALLOW_GCHEM
1555    o extended state in checkpoint_lev?, etc.
1556    o alternative ctrl/cost with tr1 or ptracer
1557    o new comlev1_bibj_ptracers
1558    o new ptracers.flow
1559    o made ptracers_forcing same as external_forcing_s
1560    o added verification for adjoint with ptracers
1561      - adm. grdchk fail so far
1562      - tlm. grdchk OK
1563      - checked tapelev/comlev recomputations: OK
1564    <<<checkpoint51b_pre
1565    
1566    checkpoint51a_post
1567    o added code for biogeochemistry package
1568      - new pkgs: dic, gchem
1569      - new subroutine in ptracers
1570    o modify code for biogeo packages
1571      - in model/src and pkg/ptracers
1572    
1573    checkpoint51
1574    o merged improved packages from ecco-branch (ecco_c51_e34) to MAIN
1575      - autodiff, ctrl, exf, grdchk, seaice
1576      kept separate packages
1577      - cost, ecco, obcs
1578    o updating verification/internal_wave, verification/lab_sea
1579      (all verif's pass on faulks.lcs.mit.edu RH7.3, g77)
1580    
1581    checkpoint50i_post
1582    o Preparing next differentiable checkpoint and sync
1583      of MAIN vs. ecco-branch
1584      - 1st step: this one is differentiable
1585      - 2nd step: next(! not this) checkpoint will have updated packages
1586                  from ecco-branch)
1587    
1588    checkpoint50h_post
1589    o new package "land": provide surface BC for AIM.
1590    o pkg/ptracers: apply exchange to all tracers after reading a pickup.
1591    o AIM: use true log-P extrapolation for near surface temp (= as in
1592        F.Molteni paper) ; update aim.5l_cs output.
1593    o New variable in PARM03 for more flexible pickups
1594    o somewhat cleaned package initialisation sequence for
1595      ctrl/ cost/ ecco/ in packages_... routines
1596    
1597    checkpoint50g_post
1598    o merged with release1_p17 (pkg/seaice and verification/lab_sea)
1599      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
1600      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
1601        made the default because of faster convergence than ADI
1602    
1603    checkpoint50f_post
1604    o exf totally restructured
1605      - replaced all exf_set_ routines by one generic exf_set_gen.F
1606        and made sure it's still differentiable
1607      - split exf_getffields.F into new exf_bulkformulae.F
1608      - exf_inscal_/exf_outscal_ suffixes consistent with field names
1609      - updated adjoint/makefile and relevant verif. accordingly
1610    
1611    checkpoint50f_pre
1612     o AIM: near surface temp evaluated from Pot.Temp: fixed for Part Cell ;
1613          + change Evap over land. (update aim.5l_cs output)
1614     o added missing .cvsignores and made uniform across expts
1615     o changed configuration of tidal_basin_2d expt
1616     o added pkg/debug functions for tracing code in fatal crashes
1617     o tidied pkg/monitor to use MONITOR_OPTIONS.h
1618     o new fn in pkg/monitor to stop model if solution grows too big
1619     o removed lots of single quotes from comments
1620    
1621    checkpoint50e_post
1622    o make KPP work with PTRACERS
1623     - fix gad_calc_rhs to call new routine kpp_transport_ptr, which is
1624       nearly a copy of kpp_transport_s
1625     - there is no analogue to SurfaceTendencyS, so I have to use
1626       gPtr(of the surface layer) instead
1627    o add a new platform SunFire+mpi (SunFire 15000) to genmake
1628    checkpoint50e_pre
1629    
1630    checkpoint50d_post
1631    o change kpp output from multiple-record state files to single-record state
1632      files analogous to write_state.F
1633    o reduce the output frequency of cg3d-related stuff to the monitor frequency,
1634      analogous to the cg2d-related output.
1635    o fix small problem with in ptracers_write_checkpoint.F: len(suff)=512,
1636      so that writing to internal file fn (with length 512) fails.
1637    checkpoint50d_pre
1638    
1639    checkpoint50c_post
1640    o fix problem in ini_procs.F when using MPI (was there since checkpoint48f)
1641    o add monitor diagnostic of vorticity (mon_vort3.F) and potential energy.
1642    o add time-average diagnostic of U*V and vertical diffusive flux for theta.
1643    o bug fixed in convective adjustment diagnostic (multi-tile set-up).
1644    o 4th Order Adv scheme: return to previous (c40pre7) masking near boundaries.
1645    
1646    checkpoint50c_pre
1647    Merging from release1_p13:
1648    o bug fix for pkg/seaice dynamic solver
1649    o Added SEAICE_initialHEFF to pkg/seaice
1650    
1651    checkpoint50b_post
1652    o store u*,v* in gU,V instead of in guNm1,gvNm1
1653    o in order to put the momForcing out of the Adams-Bashforth:
1654      move forcing & CD-scheme calls from mom_fluxform & mom_vecinv
1655      to timestep.F
1656    o new flag "useCDscheme" (default=F); replace guCD,gvCD by local arrays
1657    o re-generate output for highly sensitive test-exp:
1658       global_ocean_pressure, ideal_2D_oce, lab_sea, natl_box
1659    
1660    checkpoint50b_pre
1661    o restore the use of momAdvection & useCoriolis flags (mom_vecinv)
1662    o corrected CPP option mismatch in exf_Bulk... functions for case
1663      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
1664    
1665    checkpoint50a_post
1666    o Bug fix for merging between c50 and KPP.
1667      ikey was passed from thermodynamics to kpp_calc via
1668      common block rather than being recomputed in kpp_calc,
1669      in contradiction with new key itdkey.
1670      New key ikppkey created, and tamc.h headers updated.
1671    
1672    checkpoint50
1673    - 2nd step of merge with ecco-branch:
1674      merge changes in ecco-branch back into main trunk
1675    - bug fix in find_alpha
1676    - more storing in gmredi_calc_tensor.F, kpp_routines.F
1677    - avoid iterative loop in ini_pressure for ALLOW_AUTODIFF_TAMC
1678    - merged some sliced AD support routines
1679    
1680    checkpoint49
1681    merged from ecco-branch:
1682    o exf:
1683      - Enable initialisation of forcing fields to constant
1684        (runtime) values.
1685      - in exf_getffields.F
1686        Reduce i-/j-loop to interior domain, discarding overlaps.
1687        That also fixes wrong TAF-key computations for key_1, key_2
1688        with bulf formulae.
1689      - exf_init.F modify #ifdef for exf_init_evap
1690      - exf_getffieldrec.F, ctrl_getrec.F
1691        The following INT-usages are not safe:
1692          fldsecs  = int(fldsecs/fldperiod)*fldperiod
1693          fldcount = int(fldsecs/fldperiod) + 1
1694        and were modified.
1695    o autodiff: checkpoint_lev...
1696      - updated storing for bulk formulae (some arrays were missing)
1697      - added state for seaice package
1698      - synchronized with main branch
1699    o DIVA:
1700      Modif.s in
1701      - the_main_loop.F
1702      - the_model_main.F
1703      and added cost_final_restore.F cost_final_store.F
1704      o With these changes, it is possible to fully separate
1705        the first forward run to compute the cost function (mdthe_main_loop)
1706        and adjoint runs over individual DIVA intervals (adthe_main_loop)
1707        into separate model executions.
1708        This enables better tuning of DIVA to given queue sizes.
1709      o Loss of cost function value in consecutive DIVA runs is
1710        fixed by storing to 'costfinal' file.
1711      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
1712        beginning/end of adjoint integration is accounted for.
1713      The current changes apply to TAF-1.4.26.
1714      TAF has one remaining bug, requiring one manual change
1715      (see MITgcm manual).
1716    o cal: synchronized between MAIN and ecco-branch
1717    
1718    checkpoint48i_post
1719    o Changes to restore differentiability of code w.r.t. previous tag
1720      (mostly adding new routines to make list and replacing
1721      pressure by totPhiHyd).
1722    o Updated and merged grdchk package
1723      - has both ADM and TLM checks
1724      - works for single- and multi-proc.
1725      - output cleaned
1726      - worked successfully for parallel DIVA
1727    o genmake:
1728      - Adding -platform=SP4
1729      - Modif. for DEC Alpha (many don't have makedepend; use mkdep instead).
1730    o Modif. for DIVA:
1731      ctrl_unpack should not be called in intermediate DIVA interval.
1732      (similar thing would apply for active files such as
1733      tbar, sbar, psbar, which should not be reinitialised;
1734      only relevant for ecco-branch)
1735    
1736    checkpoint48h_post
1737    o improve "ini_p_ground" when using finite difference form for calc_phi_hyd
1738    o Added net flux to downward flux conversion to pkg/exf/exf_getffields.F
1739    o Added SEAICE_initialHEFF to pkg/seaice
1740    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
1741    
1742    checkpoint48g_post
1743    --- EOS:
1744    o compute locally the pressure for use in EOS: UNESCO, JMD95P, MDJWF
1745      store total Potential in totPhyHyd for diagnostics & EOS.
1746    o fix restart and overlap Pb when using Z-coord and EOS funct. of P
1747    --- Pressure/geopotential gradient:
1748    o use Ro_surf & R_low instead of hFac in cal_phi_hyd:
1749    o NLFS + p-coord.: eta*Alpha' is not longer lagging 1.time-step behind
1750      ( changes results of global_ocean_pressure )
1751    o NLFS + z-coord.: add eta*Rho' contribution.
1752    o accurate phiHyd when using interface-W at the middle between 2 centers
1753     ( changes results of ideal_2D_oce )
1754    o includes r* 2nd term in potential gradient.
1755    
1756    checkpoint48f_post
1757    Merging from release1_p12:
1758    o Modifications for using pkg/exf with pkg/seaice
1759      - improved description of the various forcing configurations
1760      - added basic radiation bulk formulae to pkg/exf
1761      - units/sign fix for evap computation in exf_getffields.F
1762      - updated verification/global_with_exf/results/output.txt
1763    o Added pkg/sbo for computing IERS Special Bureau for the Oceans
1764      (SBO) core products, including oceanic mass, center-of-mass,
1765      angular, and bottom pressure (see pkg/sbo/README.sbo).
1766    o Lower bound for viscosity/diffusivity in pkg/kpp/kpp_routines.F
1767      to avoid negative values in shallow regions.
1768      - updated verification/natl_box/results/output.txt
1769      - updated verification/lab_sea/results/output.txt
1770    o MPI gather, scatter: eesupp/src/gather_2d.F and scatter_2d.F
1771    o Added useSingleCpuIO option (see PARAMS.h).
1772    o Updated useSingleCpuIO option in mdsio_writefield.F to
1773      work with multi-field files, e.g., for single-file pickup.
1774    o pkg/seaice:
1775      - bug fix in growth.F: QNET for no shortwave case
1776      - added HeffFile for specifying initial sea-ice thickness
1777      - changed SEAICE_EXTERNAL_FLUXES wind stress implementation
1778    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
1779      kpp_transport_t.F, forward_step.F, and the_main_loop.F
1780    o pkg/seaice:
1781      - adjoint-friendly modifications
1782      - added a SEAICE_WRITE_PICKUP at end of the_model_main.F
1783    
1784    checkpoint48e_post
1785    o New S/R for diagnostic of bottom pressure (phi0surf was missing in c48d_post)
1786    o dynamics: change definition of computational domain & adapt mom_fluxform
1787      accordingly ; when viscA4=0, allows to run the dynamics with Olx=Oly=2.
1788    o following exp works with Olx=Oly=2 (and pass through checkbounds option):
1789        adjust_nlfs.cs-32x32x1 adjustment.128x64x1 adjustment.cs-32x32x1
1790        exp0 exp1 exp2 exp4 exp5 hs94.cs-32x32x5 hs94.128x64x5 hs94.1x64x5
1791        global_ocean.90x40x15 global_with_exf global_ocean_pressure
1792        inverted_barometer solid-body.cs-32x32x1
1793      (high order AdvScheme and/or multiDimAd works with Olx=Oly=2 ? not sure)
1794    
1795    checkpoint48d_post
1796    o in preparation for r*:
1797     a) use pre-computed gradient of hydrostatic potential:
1798        changes in timestep.F & mom_cdscheme.F affects results of ideal_2D_oce
1799     b) move phi0surf from calc_phi_hyd to calc_grad_phi_hyd:
1800        => affects results of glob_oce_pressure (different truncation error)  
1801      update output.txt of ideal_2D_oce & global_ocean_pressure
1802    
1803    checkpoint48d_pre
1804    o in preparation for r*:
1805      new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
1806      pass the 2 comp. of the grad. as arguments to momentum S/R.
1807      but for the moment, only used if it does not change the results.
1808    o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP
1809    
1810    checkpoint48c_post
1811    Modifications in treatment of initial flux forcing controls
1812    to avoid extra storing of flux fields.
1813    
1814    checkpoint48c_pre
1815    o Added tidal_basin_2d experiment (currently 1D!)
1816    o can use r* Coordinate with OBC (but Orlanski Rad. BC not yet implemented)
1817    
1818    checkpoint48b_post
1819    o r* coordinate added in #ifdef NONLIN_FRSURF block.
1820     (modification to pressure gradient not yet implemented)
1821    o mom_fluxform: new S/R mom_calc_rtrans.F computes vertical transports
1822      (for U & V) that are used for vertical advection of momentum.
1823    
1824    checkpoint48a_post
1825    o In preparation for r*, use temp. array to compute vertical transport
1826       in flux-form momentum pkg. => change results of few test-exp.
1827      Update output of: exp4, exp5, front_relax, global_ocean_pressure,
1828                        lab_sea, natl_box & plume_on_slope
1829    
1830    checkpoint48
1831    o fix small bug that was causing lot of warning (TIMER_STOP 'UPDATE_CG2D')
1832    
1833    checkpoint47j_post
1834    o add new exp. (ideal_2D_oce) to test "exotic" parameters and options.
1835    o moved adexch from forward_step to addummy_in_stepping
1836    o added exch in ctrl_map_...
1837    o aveFreq.=0. at end of cost_final to avoid overwrite in
1838      reverse checkpointing loop
1839    o Yet more changes in gmredi:
1840      * adgmredi_calc_tensor
1841        avoiding all recomputation of gmredi_slope_limit
1842      * adgmredi_x/y/rtransport
1843        added flag for excessive storing to avoid recomp. of
1844        u/v/rtans, dTdx/y/z
1845        -> this is not really necessary and very memory-consuming
1846      * adgmredi_slope_psi:
1847        consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
1848      * gmredi_slope_limit
1849        re-activated full calculation of taperfct for case 'ac02'
1850    o updating verification/ adjoints of carbon, global_ocean.90x40x15
1851    
1852    checkpoint47i_post
1853    o GM_EXCLUDE_() replace GM_TAPER_(): by default, all the code is compiled.
1854    o add GM_Small_Number & GM_slopeSqCutoff as run-time parameters (data.gmredi)
1855      default values = 1.D-12 & 1.D+48 (=> give same results as checkpoint47f_post)
1856    o cg2dTargetResWunit: define tolerance using deltaTmom (and not deltaTfreesurf)
1857    o gmredi: fix few bugs.
1858    
1859    checkpoint47h_post (duplicate tag for PH's c48 tag, in order to move c48)
1860    This will be a good checkpoint to plug into the ecco-branch.
1861    o few modif.'s to get latest version adjointed
1862      (mainly kick out code in ini_linear_phisurf)
1863    o modif's to run adjoint with exactConserv
1864    o case GM_BOLUS_ADVEC should be cleaned
1865      S/R gmredi_slope_psi should be cleaned
1866    o verification/carbon now has exactConserv=.TRUE.
1867    
1868    checkpoint47g_post
1869    o time-average AIM output: becomes independent from statvars time-average
1870      (can be used with #undef ALLOW_TIMEAVE) ; add new variables (e.g., RH)
1871    o After TAF bug fix:
1872      Tested adjoint of gmredi package.
1873      Tests were done with checkpoint47 rather than with latest
1874      checkpoint47f_post since the latter is broken for the adjoint
1875      verification/carbon/ contains both ADM and TLM gradient checks.
1876    Here they are, before they get changed/lost/stolen.
1877    Mostly modif.'s to fix numerical sensitivities.
1878    Gradient checks OK for
1879    - GM_taper_scheme:
1880      * clipping
1881      * ac02
1882      * linear
1883      * glw91
1884      * dm95
1885      * ldd97
1886    - GMREDI_OPTIONS:
1887      * GM_VISBECK_VARIABLE_K
1888      * GM_NON_UNITY_DIAGONAL
1889      * GM_EXTRA_DIAGONAL
1890      * GM_BOLUS_ADVEC
1891    in conjunction with data.gmredi parameters to be checked in
1892    in a few minutes under verification/carbon/code/
1893    
1894    checkpoint47f_post
1895    Merging from release1_p10:
1896    o modifications for using pkg/exf with pkg/seaice
1897      - pkg/seaice CPP options SEAICE_EXTERNAL_FORCING
1898        and SEAICE_EXTERNAL_FLUXES
1899      - pkg/exf CPP options EXF_READ_EVAP and
1900        EXF_NO_BULK_COMPUTATIONS
1901      - usage examples are Experiments 8 and 9 in
1902        verification/lab_sea/README
1903      - verification/lab_sea default experiment now uses
1904        pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf
1905    
1906    checkpoint47e_post
1907    o created a tag prior to creating a branch
1908    
1909    checkpoint47d_post
1910    o fixed bug in the oceanic pressure coordinates code: vertical viscosity
1911      at the bottom boundary had an erroneous half slip boundary condition
1912    o added bottom drag and no slip boundary condition capabilities to
1913      oceanic pressure coordinates code
1914    o added new verification experiment global_ocean_pressure, this experiment is
1915      also described in the tutorial section of the manual
1916    checkpoint47d_pre
1917    
1918    checkpoint47c_post
1919    o Added a verification experiment for a global cubed-sphere ocean run
1920      -  verification/global_ocean.cubed32x32x30
1921      -  uses pkg/therm_seaice and pkg/bulk_forcing
1922    
1923    o allow to run AIM physics with SPEEDY input files (from Franco Molteni)
1924    o allow a more accurate definition of Ro_Surf (selectFindRoSurf=1)
1925      when using P-coordinate; only implemented for atmospheric config.
1926    o OCEANICP & realFreshWater: include P-E direct effect on wVel ;
1927      NOTES: requires option NONLIN_FRSURF to be "#define".
1928    o update advect_xz/results/output.txt (left from checkpoint44g_post)
1929    
1930    checkpoint47b_post
1931    Merging from release1_p9:
1932    o pkg/seaice
1933      - removed GOTO's and added taf directives
1934      - double precision constants to reduce the g77 (Linux)
1935        to F77 (SGI) differences reported in release1_p8
1936    o tools/genmake
1937      - added SGI options
1938    o verification/testscript
1939      - updated to that of checkpoint47a_post
1940    o verification/global_ocean.90x40x15/input/eedata
1941      - modified for SGI f77 compatibility
1942    o verification/lab_sea
1943      - added description of sea-ice model
1944      - added missing matlab routines
1945      - added test of thermodynamics parallelization
1946    
1947    checkpoint47a_post
1948    o new pkg: aim_v23
1949     = F. Molteni atmos.physics (SPEEDY, ver23) adapted to MITgcm.
1950       for now, keep the same surface forcing as before.
1951     - Part-Cell implemented into AIM; check that Heat & Water are conserved
1952     - aim.5l_cs: use new aim pkg (run 10yr & get better results than before)
1953     - aim.5l_LatLon & aim.5l_Equatorial_Channel are still using old aim pkg
1954    o add diagnostic of surface correction term in monitor output
1955    
1956    o bulk_force and therm_seaice
1957    - Two packages:  bulk_force (Bulk forcing)
1958      and therm_seaice (thermodynamic_seaice) - adopted from LANL CICE.v2.0.2
1959    - Earlier integration from Stephaine Dutkiewicz
1960      and Patrick Heimbach.
1961    - Two ifdef statements for compile time,
1962       ALLOW_THERM_SEAICE and ALLOW_BULK_FORCE
1963    
1964    checkpoint47
1965    differentiable version of checkpoint46n_post
1966    o bug fix in quasihydrostaticterms
1967    o * "clean" adjoint code (in terms of extensive recomputations)
1968        can now be obtained for all GMREDI options (i.e. for
1969        - GM_VISBECK_VARIABLE_K
1970        - GM_NON_UNITY_DIAGONAL
1971        - GM_EXTRA_DIAGONAL
1972        - GM_BOLUS_ADVEC )
1973      * However, wrong gradient check problem remains unsolved.
1974      * New CPP options have been introduced for different
1975        tapering schemes
1976    o external_fields_load now part of differentiation list
1977    o pressure needs multiple storing;
1978      would be nice to have store_pressure at beginning or
1979      end of forward_step, e.g. by having phiHyd global (5-dim.)
1980      (NB: pressure is needed for certain cases in find_rho,
1981      which is also invoked through convective_adjustment).
1982    o recomputations in find_rho for cases
1983     'JMD95'/'UNESCO' or 'MDJWF' are OK.
1984    o #define ATMOSPHERIC_LOADING should be differentiable
1985    o ini_forcing shifted to begining of initialise_varia
1986    o Incorporating QNVS line search routines into MITgcm
1987      (this is separate code, and therefore not under pkg)
1988      lsopt/, optim/
1989    o Updated verification/carbon/
1990      - #define GM_VISBECK_VARIABLE_K
1991      - GM_taper_scheme    = 'ldd97'    
1992    
1993    checkpoint46n_post
1994    Merging from release1_p8:
1995    o verification/natl_box:
1996      updating new external_fields_load routine
1997    o New package: pkg/seaice
1998      Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
1999      The sea-ice code is based on Hibler (1979-1980).
2000      Two sea-ice dynamic solvers, ADI and LSR, are included.
2001      In addition to computing prognostic sea-ice variables and diagnosing
2002      the forcing/external data fields that drive the ocean model,
2003      SEAICE_MODEL also sets theta to the freezing point under sea-ice.
2004      The implied surface heat flux is then stored in variable
2005      surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
2006      kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
2007      non-local transport term.  Because this call precedes model
2008      thermodynamics, temperature under sea-ice may not be "exactly" at
2009      the freezing point by the time theta is dumped or time-averaged.
2010      N.B.: fairly large differences in accuracy occur across
2011            different platforms/compilers; comparison between
2012            g77 (Linux) and F77 (SGI Origin 2000/MIPSpro)
2013            generated output gives:
2014       T           S           U           V

2020      Y Y Y Y  5  5  7  7  7  8 10  9  6  6  6  6  7  5  7  5  7 FAIL  lab_sea
2021    o GAD:
2022      - generated new common blocks to account for call of
2023        same gad routines with differing traceridentities
2024        (needed to modify tracerIdentity indices in GAD.h)
2025      - generated separate common blocks for case useCubedSphereExchange
2026        (Department of Futurology)
2027      - parameter lists to gmredi_?transport: added tracerIdentity
2028      - added new key indices to tamc.h
2029    o external_fields_load:
2030      - added this routine to TAF list
2031      - needed to make some common blocks global and additional storing
2032        along the same lines as exf package (checkpoint_lev?_directives.h)
2033    o exf:
2034      updated external forcing package
2035      - bug fixes carried over from ecco-branch
2036        (missing OBCS_OPTIONS.h in two routines)
2037      - enable easy to use "no forcing".
2038      - added exf I/O for atmospheric loading
2039      - added exf I/O for runoff data
2040      - transfered scaling between exf <-> MITgcm to exf namelist
2041    o Adding new verification experiment global_with_exf.
2042      This verification experiment is almost identical to the
2043      global_ocean.90x40x15 experiment, except that it uses
2044      the exf (and cal) package instead of the
2045      external_fields_load routine (cf README file).
2046    
2047    checkpoint46m_post
2048    o modified testscript to return -- when there are no lines of "%MON" output
2049    o added new flag "quasiHydrostatic" for QH mode
2050      and new routine quasihydrostaticterms()
2051    o added 2*Omega*Cos(phi)*W to u equations (non-hydrostatic Coriolis term)
2052      New routine: mom_u_coriolis_nh()
2053    o fixed sign of non-hydrostatic metric terms in u and v equations.
2054      Depend on correct sign of gravitySign.
2055    o added work.pc* to .cvsignore in aim directories using ifc
2056    o introduced flag for controllin non-hydrostatic metric terms
2057  o removed gravitySign from PARM04  o removed gravitySign from PARM04
2058  o switched to g77/ifc from pgf77 in aim experiments  o switched to g77/ifc from pgf77 in aim experiments
2059
