Submit Notes
The config file option 'submit' was used. Benchmarks bound to a processor using numactl on the submit command.
Operating System Notes
ulimit -s (stack) set to 1048576. Large pages reserved as follows by root user: echo 4224 > /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 export HUGETLB_ELFMAP=RW
General Notes
