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 To limit dirty cache to 8% of memory, 'sysctl -w vm.dirty_ratio=8' run as root. To limit swap usage to minimum necessary, 'sysctl -w vm.swappiness=1' run as root. To free node-local memory and avoid remote memory usage, 'sysctl -w vm.zone_reclaim_mode=1' run as root. To clear filesystem caches, 'sync; sysctl -w vm.drop_caches=3' run as root. To disable address space layout randomization (ASLR) to reduce run-to-run variability, 'sysctl -w kernel.randomize_va_space=0' run as root. 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.
