Submit Notes
The numactl mechanism was used to bind copies to processors. The config file option 'submit' was used to generate numactl commands to bind each copy to a specific processor. For details, please see the config file.
Operating System Notes
Stack size set to unlimited using "ulimit -s unlimited"
Platform Notes
BIOS Configuration: Disable C1E Support, DRAM RAPL Mode, Demand Scrub, Double Refresh. Set Package C-state Limit to C0
General Notes
