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 'nodev /mnt/hugepages hugetlbfs defaults 0 0' added to /etc/fstab echo 14400 > /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
