Submit Notes
The config file option 'submit' was used.
Operating System Notes
'ulimit -s unlimited' was used to set the stack size to unlimited prior to run
Platform Notes
BIOS Settings: Hardware Prefetcher = Disabled (Default = Enabled) Adjacent Cache Line Prefetch = Disabled (Default = Enabled)
General Notes
All benchmarks compiled in 32-bit mode except 401.bzip2 and 456.hmmer, for peak, are compiled in 64-bit mode taskset was used to bind processes to cores except for 462.libquantum peak OMP_NUM_THREADS set to number of processors KMP_AFFINITY set to "physical,0" KMP_STACKSIZE set to 64M
