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 12672 > /proc/sys/vm/nr_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

  The following environment varibles were set before the runspec command:
    export HUGETLB_VERBOSE=0
    export HUGETLB_MORECORE=yes
    export HUGETLB_ELFMAP=RW
    export XLFRTEOPTS=intrinthds=1
