Submit Notes
The config file option 'submit' was used. numactl was used to bind copies to the cores
Operating System Notes
Transparent Huge Pages enabled with: echo always > /sys/kernel/mm/redhat_transparent_hugepage/enabled runspec command invoked through numactl i.e.: numactl --interleave=all runspec <etc>
Platform Notes
BIOS configuration: HP Power Profile set to Maximum Performance Thermal Configuration set to Increased Cooling
General Notes
Stack size set to unlimited using "ulimit -s unlimited"
