Compiler Notes -------------- The AMD64 AOCC Compiler Suite is available at http://developer.amd.com/amd-aocc/ Submit Notes ------------ The config file option 'submit' was used. 'numactl' was used to bind copies to the cores. See the configuration file for details. Operating System Notes ---------------------- 'ulimit -s unlimited' was used to set environment stack size limit 'ulimit -l 2097152' was used to set environment locked pages in memory limit runcpu command invoked through numactl i.e.: numactl --interleave=all runcpu 'echo 8 > /proc/sys/vm/dirty_ratio' run as root to limit dirty cache to 8% of memory. 'echo 1 > /proc/sys/vm/swappiness' run as root to limit swap usage to minimum necessary. 'echo 1 > /proc/sys/vm/zone_reclaim_mode' run as root to free node-local memory and avoid remote memory usage. 'sync; echo 3 > /proc/sys/vm/drop_caches' run as root to reset filesystem caches. 'sysctl -w kernel.randomize_va_space=0' run as root to disable address space layout randomization (ASLR) to reduce run-to-run variability. To enable Transparent Hugepages (THP) for all allocations, 'echo always > /sys/kernel/mm/transparent_hugepage/enabled' and 'echo always > /sys/kernel/mm/transparent_hugepage/defrag' run as root. To enable THP only on request for peak runs of 628.pop2_s, and 638.imagick_s, 'echo madvise > /sys/kernel/mm/transparent_hugepage/enabled' run as root. To disable THP for peak runs of 627.cam4_s, 644.nab_s, 649.fotonik3d_s, and 654.roms_s, 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' run as root.
