Operating System Notes

 'numactl' was used to bind copies to the cores
 Environment variable PGI_HUGE_PAGES set to 896
 'ulimit -s unlimited' was used to set environment stack size
 'ulimit -l 2097152'  was used to set environment locked pages in memory limit
 Set vm/nr_hugepages=1792 in /etc/sysctl.conf
 mount -t hugetlbfs nodev /mnt/hugepages
 powersave -f was used to set the CPU frequency to its maximum.
