Operating System Notes
'ulimit -s unlimited' was used to set the stacksize to unlimited prior to run
Hugepages was enabled with the following:
'nodev /mnt/hugepages hugetlbfs defaults 0 0' added to /etc/fstab
echo 900 > /proc/sys/vm/nr_hugepages
export HUGETLB_MORECORE=yes
export LD_PRELOAD=/usr/lib64/libhugetlbfs.so
Platform Notes
Power C-states enabled in BIOS Demand Scrub disabled in BIOS
General Notes
OMP_NUM_THREADS set to number of cores KMP_AFFINITY set to granularity=fine,scatter Binaries were compiled on RHEL5.5
