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


  Large pages reserved as follows by root user:
  echo 4224 > /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

  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 HUGETLB_ELFMAP=RW
   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"
