      Notes on tags used in MITgcmUV
      ==============================
+ o pkg/seaice:
+    put exchanged variable in (local) common block for MPI+Multi-Threads
+    to work (necessary with exch1, and for now with exch2 too).
+ o verification: to get more experiments tested with mpi, mth and mpi+mth,
+   change tiling of:
+    aim.5l_Equatorial_Channel, aim.5l_LatLon, dome, exp4, global_ocean.90x40x15,
+    hs94.cs-32x32x5, MLAdjust, offline_exf_seaice & tutorial_plume_on_slope
+   update output of exp:
+    exp4, global_ocean.90x40x15(+.dwslp), MLAdjust(all 5),
+    tutorial_plume_on_slope and hs94.cs-32x32x5 (use default rotationPeriod)
+   + ideal_2D_ocean: use default rotation period + test Global_Sum_SINGLECPU
+                    (note: output.txt generated on faulks using only 1 tile)
+ o eesupp & mdsio (SingleCpuIO):
+  - remove MISSING_TILE_IO (from MDSIO_OPTIONS.h), replaced by run-time
+    parameter "W2_useE2ioLayOut" (read from file "data.exch2").
+    Note: was not effective for globalFile & useSingleCpuIO=F; now fixed.
+  - move MDSIO_SCPU.h (pkg/mdsio) to EEBUFF_SCPU.h (eesupp/inc).
+  - fix GLOBAL_SUM_SINGLECPU when using Exch2; re-use same buffers and same
+    gather/scatter S/R as with SingleCpuIO (=> 1 less 2D global RL array).
+ o pkg/exch2:
+  - new code to set-up W2-Exch2 topology (replace matlab-topology-generator):
+    read parameter file "data.exch2" if it exists; otherwise try default regular
+    cube without blank-tile; new header file "W2_EXCH2_SIZE.h";
+  - update matlab-topology-generator (exch2_setup_cs6_print.m) to be compatible
+    with new code (not to be used, just as a backup solution).
+  - add examples (e.g., for lat-lon-cap_120) of parameter file "data.exch2"
+    in utils/exch2/input.
+ checkpoint61n
+ o eesupp & mdsio (SingleCpuIO):
+   - move mapping to global io-buffer inside gather_2d/scater_2d: this save
+     memory (1 less 2D global RL array); skip 1 buffer copy; and only send/
+     receive real*4 array (instead of real*8) to read/write 32.bit files.
+     (new template for gather_2d/scater_2d, new set of S/R MDS_PASS_R4,8toRL,S
+      and remove new mapping S/R)
+ o pkg/mdsio: in preparation for topology-generator within pkg/exch2:
+   - Change declaration of SingleCpuIO buffer, reduced to only 1 dim.:
+     xyBuffer_size, which is set to W2_ioBufferSize from W2_EXCH2_PARAMS.h
+     when using exch2. Add S/R to map global io-buffer to global model array.
+   - uses exch2_global_Nx,y instead of exch2_domain_nxt,nyt.
+ checkpoint61m
+ o write_utils : change WRITE_1D_R8 to WRITE_1D_RL
+   and add 3 other S/R for other types (R4,R8,RS).
+   Change calls to WRITE_0D/1D_R[4,8,S,L] to match the type of argument.
+ o eesupp/inc/CPP_EEMACROS.h (EXCH & GLOBAL_SUM/MAX macros):
+  - ensure suffix (_R4,_R8,_RS,_RL) correspondance between macro and S/R ;
+  - reduce number of macro definitions (keep only those which are used);
+    can always call directly the corrresponding S/R if needed.
+  - everywhere in the code: change macros (EXCH & GLOBAL_SUM/MAX) suffix
+    _R4/_R8 to _RS/_RL when applied to _RS/_RL variable.
+  Fixed wrong type of arg in:
+    atm2d/put_ocnvars.F cheapaml/cheapaml.F ocn_compon_interf/ocn_apply_import.F
+    ctrl/ctrl_map_ini_ecco.F seaice/seaice_do_diags.F seaice/seaice_model.F
+  To fix: global_sum of var in common block is wrong (multi-threaded) in:
+    dic/dic_atmos.F ebm/ebm_area_t.F ebm/ebm_zonalmean.F sbo/sbo_calc.F
+  To fix: aim_v23/aim_do_co2.F (BARRIER & GLOBAL_SUM within bi,bj loops)
+ o adjustment.cs-32x32x1: test "blank tiles" when compiling with mpi; 2nd
+   "nlfs" mpi test is going to stop when checking for unconnected tile egdes.
+ o eesupp/src: new S/R to stop everyone when 1 (or more) Proc. find an error
+ o pkg/exch2: new S/R EXCH2_CHECK_DEPTHS to check that unconnected tile
+   edges are closed (zero depth); might happen with "blank tiles";
+   for now, disabled if using OBCS.
+ o tools/gemake2: delete modifs from March 27-29 2009 (with option "-mpi":
+   link *_mpi files from "MODS" dir) to return to a strait-forward behavior.
+ o move read_write.F to write_utils.F ; new parameter (maxLengthPrt1D)
+   to reduce length of 1.D array print in STDOUT.
+ o adjustment.cs-32x32x1: changed to oceanic test with 1 continent
+   + use 48 tiles (16x8): this will allow to test "blank tiles".
+ o start to test MPI + multi-threaded (change testreport to skip tests
+   where number of tiles do not match).
+ o genmake2: add option "-omp" to turn on Open-MP ;
+   passed to testreport (if using -mth) ; merge few (*+mth) optfiles.
  o pkg/exch2 (+ utils/exch2): ignore blank tiles (instead of removing them)
    and keep the original tile numbering. Note: compatible with old
    W2_EXCH2_TOPOLOGY.h & w2_e2setup.F topology files.

 o Overlaps had been forgotten in calcula
+Line 86 
 o Overlaps had been forgotten in calcula
  o fix cyrus makedepend for gcc 4.4
  o experiment fizhi-cs-aqualev20:
    switching to new version of S/R GETPWHERE (#define TRY_NEW_GETPWHERE)
    and generate new output. Note: new output is much closer to the old
    one (v1.8) generated with pgf77 -O2 on Mar 14 2007 than it is from
    the previous one (v1.9) generated with pgf77 -O0 on Jun 13 2007.
  o pkg/fizhi:
   - change to avoid indices going deliberately over array-bounds
-Line 29 
 o pkg/fizhi:
+Line 102 
 o pkg/fizhi:
    (e.g., datein=dates(n) is overwritten by timein=times(n) since both
     datein & timein, resp. 2nd and 3rd arg., are pointed to the same "ndum"
     address) and produces error.
+ o tools/gemake2: (March 27-29 2009)
+   with option "-mpi": link *_mpi files from "MODS" dir (this is what
+   testreport does).
  o lab_sea experiment: change from 2x1 tiles to 2x2 tiles and regenerate output
  o pkg/seaice: fix bug in new version of S/R SEAICE_LSR.F:
     update lab_sea.lsr & lab_sea.salt_plume results
-Line 44 
 o pkg/seaice:
+Line 120 
 o pkg/seaice:
    results by setting the above flag.
    Further changes involve changes in defaults:
    - ALLOW_FLOODING is defined and turned on by default
-   - SEAICE_advSnow = .true. is now the default
+   - SEAICEadvSnow = .true. is now the default
-   - SEAICE_advSalt = .true. is now the default
+   - SEAICEadvSalt = .true. is now the default
-   - SEAICE_advAge  = .true. is now the default
+   - SEAICEadvAge  = .true. is now the default
    - SEAICE_clipVelocities  = .false. is now the default
                                       (as per J. Zhang's recommendation)
    - B-grid, and thus not tested: SEAICE_TEST_ICE_STRESS_1/EXPLICIT_SSH_SLOPE
