Submit Notes
The config file option 'submit' was used to assign benchmark copy to specific kernel thread using the "numactl" command (see flags file for details).
Operating System Notes
ulimit -s (stack) set to 1048576. Large pages reserved as follows by root user: echo 21120 > /proc/sys/vm/nr_hugepages The following environment varibles were set before the runspec command: export XLFRTEOPTS=intrinthds=1 export HUGETLB_VERBOSE=0 export HUGETLB_MORECORE=yes
