DIRECTIVES
OpenMP
SOURCE FILE MODIFICATIONS
direct SCF
Prior TSGMSG PVM message passing code replaced with MPI implementation. OpenMP directives same as for previously approved ES40 submissions.
OS configuration modified to allow additional stack space and data space per process.
GENERAL NOTES
As previously approved, this code has substantial modifications to include the OpenMP directives. A gzip file of the entire source has been submitted. In order to duplicate these results under the SPEChpc run rules, set mode=serial and adjust OMP_NUM_THREADS in MPIexec and MPIexec.slave.X to control the parallelism.
