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 stack size to unlimited prior to run
 echo 1 > /proc/sys/vm/zone_reclaim_mode
 'mount -t hugetlbfs nodev /mnt/hugepages' was used to enable large pages
 echo 36000 > /proc/sys/vm/nr_hugepages
 export HUGETLB_MORECORE=yes
 export LD_PRELOAD=/usr/lib64/libhugetlbfs.so

Platform Notes

 Patrol Scrubbing set to disabled in Maintenance Console
