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
all ulimits set to unlimited. 12800 16M large pages defined with vmo command
General Notes
Environment variables set by runspec before the start of the run: MALLOCOPTIONS = "pool" MEMORY_AFFINITY = "MCM" XLFRTEOPTS = "intrinthds=1" See the flags file for details on settings. The "IBM Power 750 Express (3.3 GHz)" and "IBM Power 755 (3.3 GHz)" are electronically equivalent. The results have been measured on the "IBM Power 755 (3.3 GHz)"
