Compiler Invocation Notes

  C/C++ compiler updated to December 2012 PTF
  Version: 12.01.0000.0002

Peak Tuning Notes

 Post-Link optimization tool used for:
 400.perlbench
      with options -O4 -omullX for optimization phase,
      and -imullX for instrumentation phase
 401.bzip2
      with options -O4 -vrox
 403.gcc
     with options -O4 -nodp -rtb
 429.mcf 445.gobmk 458.sjeng 473.astar
     with options -O3
 462.libquantum
     with options -O4 -vrox -nodp
 464.h264ref
     with options -O4 -vrox -nodp -rtb
 471.omnetpp
     with options -O3 -lu -1 -nodp -sdp 9
 483.xalancbmk
     with options -O3 -m power7

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"
