small changes associated with NonLin_FreeSurf option : * initialization (ini_psurf.F); * dump hFac fields (write_state.F); * avoid unnecessary re-computation (forward_step.F initialise_varia.F calc_surf_dr.F);
Bringing comments up to data and formatting for document extraction.
Moved TR1.h headers between ifdef ALLOW_PASSIVE_TRACER.
o Added grdchk package handling o Added passive tracer handling
Moved cg3d_x into DYNVARS.h and renamed it to phi_nh. - cg3d and cg2d now look more similar - output formatted to fit Chris's tastes (I think)
See doc/tag-index and doc/notes_c37_adj.txt Preparation for stand-alone autodifferentiability.
change output file name : Eta. instead of PS. (as model variable name)
separate the state variable "eta" from the 2D solver solution cg2d_x
move the IO at the end of a time step
Moved I/O of wVel outside of N-H CPP regions
Made sure each .F and .h file had the CVS keywords Header and Name at its start. Most had header but very few currently have Name, so lots of changes!
Restored to default format of output. Still supply option for alternate method (multiple records per variable/file) but since it's broken (see comments in file) this is not publicized nor supported. :)
Rescaling of forcing fields done immediately after reading fields.
Removed unused variables and fixed some unitialized variables.
Changed some erroneous declarations of myCurrentTime (sometimes myTime) from REAL to _RL. This probably was caught before because most people are using -r8 compile option in conjuction with REAL4_IS_SLOW which converts everything to real*8. Spotted by C.E.
Implemented new I/O package (mdsio.F). This package does parallel
I/O in much the same way as dfile.F used to except it uses "direct
access" rather than (f77) unformatted sequential access.
Problems with dfile.F package included:
o unnecessary memory use (each process had two global sized buffers)
o inability to read the files it had written without post-processing
o "tiled" files were tiled by process/thread rather than actual tiles
o created huge numbers of files with no alternatives
Features of the mdsio.F package:
o direct-access binary writes
o no excessive memory use
o ability to read/write from multiple record files
o "tiled" files are based on "WRAPPER" tiles so that the number
and content of files is independent of the number of threads
and/or processes
o option to create single "global" files rather than "tiled" files
o ability to read both "global" and "tiled" files
[Caveat: the tiling of files must match the model tiles]
o checkpoints now use a single file per model section
ie. one file for the hydrostatic model core, one file
for the non-hydrostatic extensions and one file for the C-D
extensions
o the mid-level I/O routines now is broken into more source files
read_write_fld.F supplies basic I/O routines with the same interface
as the original I/O package
read_write_rec.F supplies I/O routines which allow multiple records
write_state.F writes the model state
checkpoint.F supplies the read/write checkpoint routines
All the example input data has had to be modified to be direct-access.
Otherwise only routines that used I/O have been affected and not
all of those have been due to the continuity of arguments in
the read_write_fld.F routines.
What needs to be done? We have to create a suite of conversion
utilities for users with old-style data. Also supply the option
for using old-style I/O, not just for die-hards but for reading
data too extensive to be converted. And more...
