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. ulimit -n (open files) set to 500000. Large pages reserved as follows by root user: echo 30000 > /proc/sys/vm/nr_hugepages echo 6000 > /proc/sys/vm/nr_overcommit_hugepages
Platform Notes
Service processor memory mirroring property disabled.
General Notes
The following environment varibles were set before the runspec command: export HUGETLB_VERBOSE=0 export HUGETLB_MORECORE=yes export XLFRTEOPTS=intrinthds=1
