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 4224 > /proc/sys/vm/nr_hugepages Additional filesystem options: data=writeback,noatime The following environment varibles were set before the runspec command: export HUGETLB_VERBOSE=0 export HUGETLB_MORECORE=yes export XLFRTEOPTS=intrinthds=1
Platform Notes
This Compute Node is housed in an "IBM Flex System Enterprise Chassis" The Maximum Power Limit for this Compute Node was set according to recommendation on "IBM Chassis Management Module"
