Submit Notes
The config file option 'submit' was used. numactl was used to bind copies to the cores
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 156000 > /proc/sys/vm/nr_hugepages HUGETLB_MORECORE=yes export LD_PRELOAD=/usr/lib64/libhugetlbfs.so
