Operating System Notes

 'ulimit -s unlimited' was used to set the stacksize to unlimited
 '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

 Load Default BIOS Settings and then change the following
   Turbo Boost Power Optimization set to Traditional

General Notes

 OMP_NUM_THREADS set to number of cores
 Binaries compiled on RHEL 5.5
