Submit Notes
The taskset mechanism was used to bind copies to processors. The config file option 'submit' was used to generate taskset 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" Transparent Huge Pages enabled with: echo always > /sys/kernel/mm/redhat_transparent_hugepage/enabled
Platform Notes
As tested, the system used a Supermicro CSE-732D2-500B chassis. The chassis is configured with a PWS-502-PQ power supply, 1 SNK-P0046A4 heatsink, as well as 1 FAN-0124L4 front cooling fan and 1 FAN-0124L4 rear exhaust fan.
General Notes
Environment variables set by runspec before the start of the run: LD_LIBRARY_PATH = "/usr/cpu2006/libs/32:/usr/cpu2006/libs/64" Binaries compiled on a system with 1x Core i7-860 CPU + 8GB memory using RHEL5.5
