     Notes on tags used in MITgcmUV
     ==============================
 
+o use standard version of PTRACERS_INI_VARIA in tutorial_tracer_adjsens
+  (identical results) and the standard version of EXTERNAL_FIELDS_LOAD
+  in natl_box (affects results @ truncation level: update output.txt)
+o multi-threading and IO:
+  - replace some call to MDSIO S/R by the corresponding READ/WRITE_FLD S/R.
+  - remove most of BEGIN_MASTER/ END_MASTER around READ/WRITE_FLD S/R calls
+    (needed to work with SingleCpuIO): tested in all verif. exp.
+o GAD: use simpler DST3 formulation as default (old version left within #ifdef)
+  affects the results (but none of the verification test uses this scheme).
+o Adding some pkg/diagnostics capability to pkg/seaice
+  (will certainly be subject to changes)
+o ctrl: adding new control variables:
+  lwflux, lwdown, evap, snowprecip, apressure, runoff
+
+checkpoint58q_post
+o added CPP_EEOPTIONS.h flag DISABLE_MPI_READY_TO_RECEIVE.  Speeds up
+  1/6-deg Southern Ocean configuration by 8% on IBM Datastar and
+  high_res_cube configuration by 4% on Columbia.
+o clean-up multi-threaded problems (reported by debugger tcheck on ACES);
+  add (in global_with_exf/code) a version of EXF_INTERP_READ without
+  dynamical allocation (seems to work in multi-threaded).
+o new function "MASTER_CPU_IO" (=T if master thread & master CPU, if using
+  single CPU io) so that TAF does not have to see EESUPPORT.h
+o pkg/seaice: implement sea-ice loading (when using RealFreshWaterFlux)
+
+checkpoint58p_post
+o obcs: stop if obcs is used with useCDscheme = .true.
+o shelfice: 
+ - fix a sign error so that no slip at shelfice interface works
+ - remove stop for combination non-hydrostatic code and shelfice. That does 
+   not mean, that the results are correct, but at least they are numerically
+   stable
+o diagnoctics: modify UVELPHI and VVELPHI to include hfac (i.e. mass-weighted)
+o added adjoint exch routined for all exch*3d* routines
+  and updated flow directives
+
+checkpoint58o_post
+o replace calls to EXCH_Z & EXCH_UV_AGRID: use the new _3D_ version ;
+  remove old subroutines (_XY_ & _XYZ_); update the adjoint version.
+o change controling S/R for writing pickup file (new S/R do_write_pickup)
+  and clean-up reading/writing of pickup files.
+o fix local version of read/write pickup (NH part) in rotating_tank/code
+o simplify EXCH interface:
+ - change _XYZ_ interface to _3D_ subroutine (with 3rd dim in argument list)
+ - not often used EXCH S/R (exch_z, exch_uv_agrid): keep only the _3D_ version
+o added the regrid package
+o shelfice: 
+ - add a simple boundary layer scheme to reduce noise
+ - fix the indexing in shelfice_u/v_drag so that there will be actually drag
+
+checkpoint58n_post
+o fix globalArea multi-threaded calculation: need to apply GLOBAL_SUM to 
+   local variable (not in common block).
+o lot of small changes for multi-threaded. Most tests (using OMP & ifort) pass. 
+  - still problems with pkgs: mnc, exp2, dic, cal, exf (and probably more); 
+  - still BEGIN_MASTER/END_MASTER to remove around READ/WRITE_FLD S/R calls
+    to work with SingleCpuIO.
+o add "_d 0" to real constant of pkg/cfc subroutines ; 
+   update exp. cfc_exemple & tutorial_cfc_offline output files.
+o multi-threading and IO:
+  - all threads call READ_FLD S/R (needed if using SingleCpuIO): 
+    (no BEGIN_MASTER/ END_MASTER around the call, but inside MDSIO S/R.
+  - barrier before and after reading.
+  - stop if other than master is calling MDS_WRITELOCAL (if #undef IO_THREAD_SAFE)
+  - avoid using MDS_WRITELOCAL for LAND pkg output.
+  - new S/R AIM_WRITE_PHYS (replaces AIM_WRITE_LOCAL) to write AIM physics
+    common-block variables ; Allows multi-threading with master-thread IO.
+o change default MAX_NO_THREADS from 32 to 4 ; 
+  and stop cleanly when MAX_NO_THREADS is too small. 
+o add S/R BAR_CHECK to check multi-threaded barrier synchronization
+
 checkpoint58m_post
 o add a Non-Hydroatatic test (with 3-D Coriolis, NHMTerms, biharmonic Visc.
    and side-drag) on CS-grid : global_ocean.cs32x15.viscA4
