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 -s (open files) set to 500000. Filesystem cache changed as follows by root user: echo 150 > /proc/sys/vm/vfs_cache_pressure Large pages reserved as follows by root user: echo 6000 > /proc/sys/vm/nr_hugepages echo 30000 > /proc/sys/vm/nr_overcommit_hugepages The Apache C++ Standard Library V4.2.1 was installed from http://stdcxx.apache.org/download.html using: gmake BUILDTYPE=8d CONFIG=gcc.config
Platform Notes
Service processor memory mirroring property disabled. Hardware Page Table (HPT) ratio changed as follows by root user on Hardware Management Console (HMC): chsyscfg -m <CEC NAME> -r prof -i "name=<PROFILE NAME>,lpar_name=<PARTITION NAME>,hpt_ratio=1:512"
General Notes
The following environment varibles were set before the runspec command: export HUGETLB_VERBOSE=0 export HUGETLB_MORECORE=yes export XLFRTEOPTS=intrinthds=1 export HUGETLB_ELFMAP=RW
