Compiler Invocation Notes

For more information about IBM Advance Toolchain, including support, see
ftp://linuxpatch.ncsa.uiuc.edu/toolchain/at/suse/SLES_11/at6.0/release_notes.at6.0-6.0-1.html

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 8448 > /proc/sys/vm/nr_hugepages

  The following environment varibles were set before the runspec command:
    export HUGETLB_VERBOSE=0
    export HUGETLB_MORECORE=yes
