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" Filesystem page cache cleared with: echo 1> /proc/sys/vm/drop_caches runspec command invoked through numactl i.e.: numactl --interleave=all runspec <etc>
Platform Notes
Default BIOS Settings were used. Oracle's Sun Fire X4470 M2 is now known as the Sun Server X2-4.
General Notes
Environment variables set by runspec before the start of the run: LD_LIBRARY_PATH = "/data1/cpu2006v1.2/libs/32:/data1/cpu2006v1.2/libs/64" Binaries compiled on a system with 1x Core i7-860 CPU + 8GB memory using RHEL5.5
