Changes to restore/introduce true shared memory (i.e. pure SMP model) support
for lat-lon, cartesian and cube.
o Threads support restored for global_sum, global_max.
Needed COMMON blocks in place of stack variables
for work space.
o COMMON added for temps that are exchanged
shap_filt, solve_for_pressure
o exch...template edits to allow multithreaded calling
of cube exchanges. Cube exchanges are done single threaded,
sequential at the moment and are hard coded for six-tile,
one tile per face configuration.
o Threading support only tested on Sun SMP (6500) system.
o Default is SYSTEM() exists (check_threads.F), and barrier and memsync
are used for threaded exchanges (ini_communications_patterns).
o Killed K-level plot (ini_masks_etc.F). Overlaps not set in
multi-threads (local array), so fails in plot_field().
o Fixed t-ave of phihyd ( DYNAMICS() ). Can only do it for
first tile.
o Added commented out nTx settings to hs94.cs-32x32x5 eedata.
#nTx=2
#nTx=3
#nTx=6
Need to activate for setenv PARALLEL
o Multi-threaded pickup is 100% validated.
Testing notes
o Code passes "testscript" tests.
o To get "hs94.cs-32x32x5" to run OK need to patch
dynamics.F. Patch is in hs94.cs-32x32x5/code/dynamics.patch.
o Multithreading only tested on Sun 6500 SMP for hs94.cs and
hs94.128. hs94.128 was OK at c37 but has a problem under multi-threading
at pre38 at the moment.
o Under Solaris need one of
setenv PARALLEL 2
setenv PARALLEL 3
setenv PARALLEL 6
setenv PARALLEL 8 ( hs94.128 only )
- and -
setenv STACKSIZE 16384
o Under Solaris f77 need to remove -u from Makefile FOPTS for compiling
fftpack.o. Need to declare everything in fftpack or have
custom compile options for fftpack.F to fix this.
