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
Default BIOS settings were used.
