     Notes on tags used in MITgcmUV
     ==============================
 
+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).
+
+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.
