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:
KMP_AFFINITY = "granularity=fine,scatter"
LD_LIBRARY_PATH = "/usr/cpu2006/libs/32:/usr/cpu2006/libs/64"
OMP_NUM_THREADS = "4"

 Binaries compiled on a system with 1x Core i7-860 CPU + 8GB
 memory using RHEL5.5
