5      ==============================      ==============================
6    
7    o pkg/rbcs:
8      - replace rbcsInIter by rbcsForcingOffset, the time in seconds at the
9        beginning of the first rbcs forcing period.
10      - add option rbcsSingleTimeFiles that makes rbcs read forcing data like the
11        offline package, i.e., one file per time, labeled by iteration number;
12        deltaTrbcs sets the timestep with which the data was generated;
13        rbcsIter0 is the forcing iteration corresponding to rbcsForcingOffset.
14      - rbcsForcingCycle=0 makes forcing non-cyclic.
15      - make arithmetic safe for negative times and odd forcing periods.
16    
17    checkpoint62n (2010/11/09)
18    o pkg/seaice:
19        fix masking in free-drift S/R ; update results of exp. lab_sea.fd
20    o pkg/obcs:
21       New S/R to copy tracer value from the OB location to narrow band region
22        (width = same as overlap) beyond the OB: preserve OB value (needed for
23        high-order scheme) which were overwritten by EXCH call if in overlap
24        region. Applied to theta, salt, ptracer and advected seaice variables.
25       With seaice: use maskInC in similar way as in gad_advection.F,
26        in seaice_advection.F and advect.F.
27       Update output of experiment seaice_obcs and change exp4 to test OBCS with
28        4th order Adv.Scheme. for pasive salt and ptracer.
29    o tools/genmake2:
30      - when looking for an optfile (not specified), only search for Fortran compiler
31        (remove sym-link test + setting of CPP + makedepend check + C-compiler check)
32      - in get_fortran_c_namemangling: use "$CC $CFLAG" to compile C test programm
33        (instead of "$MAKE genmake_test.o" since an existing Makefile can be wrong)
34      - set default for CPP to "cpp -traditional -P" (was the case without specifying
35        an optfile, but otherwise default was just "cpp".
36      - comment out PLATFORM=$p_PLATFORM (no idea where p_PLATFORM comes from)
37      - when "CC" is not set in the optfile, look for possible C compiler
38        (instead of just setting CC=cc)
39      - put back version v.169 modif (from 2008/02/15), was dropped in v.173 changes:
40        => add a ".F" to ".o" rule for source files with no "#include" (such as
41           port_rand.F); otherwise, default ignores FOPTIM and just uses FFLAGS.
42      - move gfortran before g77 in list of possible Fortran compiler (consistent
43        with reference compiler switch from g77 to gfortran)
44    o pkg/seaice:
45      o remove SEAICE_OLD_AND_BAD_DISCRETIZATION-code, add a test to
46        seaice_check that stops the model, when the CPP flag is used.
47      o seaice_growth.F: make capping of ice volume conserving by returning the
48        capped ice as freshwater to EmPmR. This does not change the verification
49        experiments but will change runs where the capping is acutally active
50    o change reference platform+compiler from faulks+g77 to baudelaire+gfortran
51      (except the 2 fizhi test exp.); update output of exp.: bottom_ctrl_5x5,
52         global_ocean.cs32x15 (icedyn, thsice, AD thsice), global_ocean_ebm (AD),
53         lab_sea (fd, hb87, salt_plume), MLAdjust (3/5) and vermix (dd)
54    o tools/genmake2:
55      - merge genmake_warnings & genmake_errors into 1 log file: "genmake.log")
56      - change DUMPSTATE default to false (can use "-ds" option to switch it to T)
57      - clean previous genmake log files before anything else.
58      - change Makefile to remove testreport log files (*.tr_log) and genmake log
59        files only with "CLEAN" target (instead of "Clean");
60    o pkg/generic_advdiff:
61      Change OBCS in multiDim advection (gad_advection.F):
62       Use maskInC to prevent intermediate update of tracer-field in OB regions,
63       thus keeping current-time-step OB values; and remove the call to OBCS_APPLY
64       which were applying future time-step OB values.
65      This way, all explicit calculations use current-time-step OB values
66       (simpler and more consistent).
67      Affects results when set-up uses time-varying OBC and multi-dim advection;
68       update output of experiment seaice_obcs.
69    o pkg/seaice:
70      move OPTIONS (formerly locally defined) to SEAICE_OPTIONS.h:
71       this includes SEAICE_GROWTH_LEGACY (+ SEAICE_DO_OPEN_WATER_GROWTH &
72         SEAICE_OCN_MELT_ACT_ON_AREA ) and SEAICE_SOLVE4TEMP_LEGACY.
73      Default (pkg/seaice/SEAICE_OPTIONS.h) is to define SEAICE_SOLVE4TEMP_LEGACY
74       but leave SEAICE_GROWTH_LEGACY undef ; For now, keep verification exp
75       unchanged (SEAICE_GROWTH_LEGACY defined in */code*/SEAICE_OPTIONS.h)
76    o pkg aim (2010/10/26):
77      - Introduce ALLOW_INSOLATION, moving toward a more general incoming solar radiation
78        formulation with obliquity, eccentricity, ... as run-time parameters,
79      - Introduce diagnostics for top-of-the-atmaophere incoming solar radiation and
80        upward shortwave radition at the surface (all-sky and clear-sky).
81    o pkg/obcs:
82      - writing sections with globalFiles=T does not work: switch to tiled-files
83        when writing sections for OBCS (change pkg/rw/write_rec.F accordingly).
84      - fix index bug (OB_Ie -> OB_Iw_) in obcs_apply_uvice.F
85      - apply OBCS_SEAICE_COMPUTE_UVICE to both uice and vice at all obcs
86    
87    checkpoint62m (2010/10/21)
88    o pkg/seaice: vectorize seaice_solve4temp.F
89      - move iterations loops outside of i/j-loops
90      - requires 2D arrays for TB and effConduct
91      - add 2D iceOrNot to replace HICE_ACTUAL.GT.0, as HICE_ACTUAL is
92        modified in this routine
93      - a little bit of clean up, adjusting indentation, etc.
94      - replaced a few TEN**a by exp(a*log(10.)) in new code for better
95        performance and '**TWO' by '**2' (because TWO is a float),
96        replaced ONE, ZERO
97    o eesupp/src:
98       fix flow dir for exch1_z_RX_cube, exch1_uv_RX_cube & exch1_bg_RX_cube
99    o pkg/seaice/seaice_growth.F
100      Revision 1.89 of seaice_growth.F completes the overall october 2010 revision and
101      merging process. The merged routine has two branches, and one activates the 'evolution'
102      branch by setting SEAICE_GROWTH_LEGACY to undef (at the top of the routine for now).
103      In summary, here is what the '10/10 revision' did consist of
104        part 1: seaice_growth.F revisions 1.71 to 1.75
105          - Preliminary seaice_growth.F clean-up, keeping test results strictly unchanged.
106            The emphasis here was on improving readability (e.g. by trying to use meaningful
107            variable names) and modularity (e.g. by adding arrays to store heff etc. updates).
108        part 1.5:
109          - revising the lab_sea experiment to make it a more useful (i.e. stable
110            and representative of an actual model run). This was done by generating a
111            (winter) pickup to start from, switching back the main experiment dynamic
112            solver from evp to lsr, having one of the experiments use the free drift solution.
113        part 2: seaice_growth.F revisions 1.76 to 1.85
114          - Sorting out hard-coded constants that prevented heat and fresh water conservation.
115          - Sorting out the various fields units and sign (set early on and reset at the end)
116            to avoid numerous scalings/re-scalings. By v1.85 the basic unit for ice, heat and
117            fresh water stock is 'effective ice meters', and >0 implies more ice/snow.
118          - Using tendency terms arrays (d_HEFF* etc.) to alleviate remaining code locks,
119            and simplifying logical expressions to further improve readibility.
120        part 3: seaice_growth.F revisions 1.86 to 1.89
121          - Re-organize the blocks of code more logically.
122          - Merging the '_if.F' pieces that add something new.
123    o pkg/thsice:
124      - vectorize thsice_solve4temp and thsice_get_exf.
125        Problem: thsice_solve4temp has an unvectorizable statement that
126        might also be problematic for TAF
127      - thsice_get_exf: add the ALLOW_BULK_LARGEYEAGER04 CPP-flag. This
128        does not change the verifcation experiment, but will change all
129        experiments that have this flag undefined (not tested in verification);
130        a little reorganization to save a few 2D fields and recomputations
131      - 1st step of revisiting thsice adjoint (major recomp. sorted out)
132      - 2nd step:  fix some store dirs
133        o seems to work somewhat, i.e. using ifort but not g77
134        o likely cause are incomplete init. or recomputation
135        o start verification/global_ocean.cs32x15/input_ad.thsice
136    o pkg/obcs: add support for exch2
137      - the position of the boundary and prescribed values are specified using
138        a global domain with exch2 facets stacked
139        - in x for N,S boundaries (like W2_mapIO=-1)
140        - in y for E,W boundaries (so E,W boundaries do not overlap)
141    o pkg/mdsio: add support for writing global sections with exch2
142        file layout is as for obcs described above:
143        - for x-z sections, facets are stacked in x (like W2_mapIO=-1)
144        - for y-z sections, facets are stacked in y
145    o pkg/thsice:
146       - change a few routines for better vectorization: thsice_albedo.F,
147         thsice_step_temp.F, and in thsice_calc_thickn.F. Results are
148         not affected, but in particular the latter routine has changed
149         dramatically (not necessarily easier to read now).
150       - re-arrange calculation in THSICE_SOLVE4TEMP: move outside of i,j loops
151       iteration loop and call to S/R THSICE_GET_BULKF & THSICE_GET_EXF.
152    o verification/lab_sea:
153      - overhaul of the forward model experiments. The main motivation
154        for this revision is that lab_sea has proven quite fragile (when
155        changing the sea-ice code, and switching platforms) to a point
156        when failures were very hard to attribute to specific code problems.
157      - the suspected reason for this fragility is noise amplification by evp so,
158        to start with, we decided to replace evp with lsr in the main experiment.
159      - the input.lsr experiment thus became obsolete and was removed.
160      - it was replaced with the input.fd experiment that uses an
161        analytical "free drift" solution as the ice velocity field.
162      - Taken together, input (lsr), input.fd (free drift) and input.hb87 (evp)
163        will hopefully allow us to discriminate problems due to dynamic solvers
164        from problems due to the thermodynamic code. input.salt_plume (lsr) allows
165        us to test additional options, along with the salt plume package.
166      - Finally a pickup was generated (at the end of a one year run) to
167        make the tests more representative of an actual model run. Previously
168        the tests starting point was a 1m thickness of ice everywhere.
169    o pkg/seaice:
170      - introducing S\R seaice_freedrift.F that compute the
171        analytical solution to an approximate ice momentum
172        equation (i.e. the simple stress/coriolis balance).
173      - define SEAICE_ALLOW_FREEDRIFT to trigger the computation
174        of the free drift velocity field, and enable its use.
175        To actually use the free drift solution as the model ice
176        velocity field set SEAICEuseFREEDRIFT to .TRUE. in data.seaice.
177    o move "useOASIS" from PARAMS.h to EEPARAMS.h and read it from "eedata"
178    
179    checkpoint62l (2010/10/04)
180    o pkg/seaice:
181      -fix the USE_ORIGINAL_SBI version (for variable freezing point);
182      -use "celsius2K" in SEAICE_VARIABLE_FREEZING_POINT and in new
183       version (with USE_ORIGINAL_SBI undef);
184    o add hooks for new packages OASIS, the package will follow
185      (hooks exclude the seaice pkg for now)
186    o pkg/autodiff: ALLOW_AUTODIFF_WHTAPEIO
187      Option to use mdsio_read_whalos.F/mdsio_write_whalos.F,
188      rather than mdsio_readvector.F/mdsio_writevector.F, within
189      adread_adwrite.F to read/write adjoint-related tapes to disk.
190    o eesupp and pkg/mdsio: ALLOW_WHIO
191      Option to write/read 2D fields to files including tiles halos.
192      The main purpose is for adjoint related "tape I/O".
193      The secondary purpose is for debugging phases.
194      A word on those rather specifically intended purposes.
195      The code was meant to be stripped down to the bare minimum.
196      Typically, there is a unique and basic mapping to the global
197      buffer (tile by tile, then proc by proc, then level by level), and
198      byteswaps and meta-files are omitted. Indeed the (*_WH*) code is not
199      meant to generate user friendly outputs of various shapes and forms.
200      Rather it is intended, for the knowledgeabale developers,
201      to be largely independent of the many mdsio options, to allow
202      outputs of tiles+halos in debugging phases and in adjoint runs,
203      and to allow some flexibility in tuning (adoint) I/O depending on each
204      file system behavior. With regard to tuning, most of the potential knobs
205      (to leave files open, to allocate the I/O indep. of usesinglecpuio,
206      to specify directories, to specify the typical size of I/O calls, etc.)
207      are not yet included, and will be added if they prove useful.
208    o pkg/seaice:
209       fix uninitialised arrays in USE_ORIGINAL_SBI version of seaice_solve4temp.F
210    o pkg/seaice:
211       new S/R seaice_solve4temp.F: this is the merged version of Ian Fenty
212       code (seaice_budget_ice_if.F) which enable to recover old standard
213       code (seaice_budget_ice.F) when option USE_ORIGINAL_SBI is defined.
214       temporary: add "#define USE_ORIGINAL_SBI" at the top of seaice_solve4temp.F.
215    o model/src (rStar):
216       use simple average (not area weighted) of rStarFac at U,V point when using
217       vectorInvariant and selectKEscheme=1,3 (consistent with mom. vertical advection)
218       update output of exp. fizhi-cs-32x32x40 and fizhi-cs-aqualev20.
219    
220    checkpoint62k (2010/09/17)
221    o adjoint
222       * changed verification/global_ocean.cs32x15 ; adjoint now tests

224       * some more modifs required for ECCO-GODAE v4
225    o pkg/seaice
226       add SEAICE_AGE_VOL option to use volume instead of area for
227       integrating SEAICE_AGE
228    o model/src:

232       option for ptracer to convert Salt Relax into additional EmP.
233        tested in exp. global_ocean.90x40x15.dwnslp (update output)
234    
235    checkpoint62j (2010/08/25)
236    o pkg/ggl90:
237       other minor changes: remove 3-D temp array gTKE (+ add argument myIter)
238    o pkg/dic: car_flux.F, phos_flux.F
239      - reduce number of exp-calls in order to improve performance
240      - clean up a little (replace fields by their macros, etc., fix
241        typo in CPP-flag)
242    o pkg/ggl90: minor changes
243      - GGL90diffKrS was removed --> always use GGL90diffKr
244      - GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
245      - hack of mxlMaxFlag=2 --> ensure mixing between first and second level
246        (commented out for now)
247      - change in max/min operations to ensure that smoothing is ok
248      - smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
249      - always use diffKrNrT as background profile (i.e. never use diffKr field)
250    o pkg/cfc: bug fix, AREA(i,j,1,bi,bj) -> AREA(i,j,bi,bj)
251    o pkg/dic:
252      - model/src/impldiff.F: if TARGET_NEC_SX, extend loop ranges for better
253        vectorization
254      - small bug fix in insol for the unlikely case of a cartesian grid
255      - towards vectorizing the dic package: bio_export.F, car_flux.F, phos_flux.F
256        + now vectorize, which also removes adjoint recomputations;
257        + replace integer maksp1 by _RL maskp1
258        + replace a**x by exp(x*log(a)) in phos_flux.F for speed
259

277      - fix for case pkg/pkg_depend is missing (was hanging before);
278      - add option "-pgroups" to specify a different pkg_groups than the default.
279    o verification/adjustment.cs-32x32x1:
280       add a "minimal" set-up test (code_min & input_min) which only compiles
281       eesupp/src and the 2 pkgs (exch2 & debug) which don't need model/src & inc.
