Submit Notes
The config file option 'submit' was used to assign benchmark copy to specific kernel thread using the "bindprocessor" command (see flags file for details).
Operating System Notes
Environment variables set by runspec before the start of the run: MALLOCOPTIONS = "pool" MEMORY_AFFINITY = "MCM" XLFRTEOPTS = "intrinthds=1" All ulimits set to unlimited. 12800 16M large pages defined with vmo command See the flags file for details on settings.
