Operating System Notes

 'ulimit -s unlimited' was used to set the stack size to unlimited prior to run
 OMP_NUM_THREADS set to number of cores
 KMP_AFFINITY set to granularity=fine,scatter
 KMP_STACKSIZE set to 200M

Platform Notes

 Fan speed set to Full Speed in BIOS Setup.
 As tested, the system used a Supermicro CSE-827H-R920B chassis.
 The chassis is bundled with a PWS-920P-1R power supply, SNK-P0046P heatsink,
 and 4 FAN-00111L4 cooling fans.

General Notes

 Binaries were compiled on SLES 10 with Binutils 2.18.50.0.7.20080502
