Added yet another Hyades only path for the two-proc libraries
Set LIBS properly for JAM libaries. (affects Hyades only)
Tidied up the options for the Linux platform.
Minor mods for compiling on T3E.
Added "JAM" routines for use with Artic network (Hyades cluster).
Set value for WORDLENGTH on all platforms in genmake.
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...
Changes for linux and command line operation.
Change of rule "Clean". Clean used to remove *.[Fc] but this might be dangerous. So now it removes only links.
Changes to allow for atmospheric integration builds of the code
Changes to support - g77 compilation under Linux - LR(1) form of 64-bit is D or E for constants - Modified adjoint of exch with adjoint variables acuumulated.
Correction to missing file tim.c and genmake for checkpoint15
Changes for new exchange routines which do general tile <-> tile connectivity, variable width overlap regions and provide hooks for shared memory and DMA protocols like Arctic, Memory Channel etc..
Added changes for SGI onyx support HP Exemplar support from Dimitri
We decided to skip the KAP preprocessor stage on the DEC Alpha's by default. (KAP isn't always available, even on our own well maintained platforms...)
Tidy up configure (now genmake!) and doc/README for release of checkpoint12.
