Submit Notes
The numactl mechanism was used to bind copies to processors. The config file option 'submit' was used to generate numactl commands to bind each copy to a specific processor. For details, please see the config file.
Operating System Notes
Stack size set to unlimited using "ulimit -s unlimited"
Platform Notes
Default BIOS settings were used.
General Notes
Environment variables set by runspec before the start of the run: LD_LIBRARY_PATH = "/home/cpu2006/libs/32:/home/cpu2006/libs/64" Added glibc-static-2.12-1.47.el6.x86_64.rpm to enable static linking Transparent Huge Pages enabled with: echo always > /sys/kernel/mm/redhat_transparent_hugepage/enabled Filesystem page cache cleared with: echo 1> /proc/sys/vm/drop_caches runspec command invoked through numactl i.e.: numactl --interleave=all runspec <etc>
