Peak Tuning Notes
fdpr binary optimization tool used for: 401.bzip2 473.astar with options: -O4 -vrox -m power7 403.gcc 445.gobmk 458.sjeng with options: -O3 -m power7 429.mcf 483.xalancbmk with options: -O4 -nobp -m power7 456.hmmer 462.libquantum with options: -O3 -lu -1 -nodp -sdp 9 -m power7 464.h264ref with options: -O4 -vrox -RD -m power7
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" The "IBM Power 750 Express (3.61 GHz)" and the "IBM Power 755 (3.61 GHz)" are electronically equivalent. The results have been measured on the "IBM Power Express 750 (3.61 GHz)".
