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" Hardware Prefetch Disabled, Adjacent Sector Prefetch Disabled 'ulimit -s unlimited' was used to set the stack size to unlimited prior to run
