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.
New experiment: 3-D Held and Suarez '94 on cubed sphere.
file eedata was initially added on branch pre38.
