Operating System Notes

 'ulimit -s unlimited' was used to set the stacksize to unlimited prior to run
 'mount -t hugetlbfs nodev /mnt/hugepages' was used to enable large pages
 echo 1800 > /proc/sys/vm/nr_hugepages
 export HUGETLB_MORECORE=yes
 export LD_PRELOAD=/usr/lib64/libhugetlbfs.so

Platform Notes

 Default BIOS settings were used.
