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