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 'ulimit -l 2097152' was used to set environment locked pages in memory limit runcpu command invoked through numactl i.e.: numactl --interleave=all runcpu Set dirty_ratio=8 to limit dirty cache to 8% of memory Set swappiness=1 to swap only if necessary Set zone_reclaim_mode=1 to free local node memory and avoid remote memory sync then drop_caches=3 to reset caches before invoking runcpu dirty_ratio, swappiness, zone_reclaim_mode and drop_caches were all set using privileged echo (e.g. echo 1 > /proc/sys/vm/swappiness). Transparent huge pages set to 'always' for this run (OS default) Environment Variables Notes --------------------------- Environment variables set by runcpu before the start of the run: LD_LIBRARY_PATH = "/home/cpu2017/amd_rate_aocc200_rome_C_lib/64;/home/cpu2017/amd_rate_aoc c200_rome_C_lib/32:" MALLOC_CONF = "retain:true" General Notes ------------- Binaries were compiled on a system with 2x AMD EPYC 7601 CPU + 512GB Memory using Fedora 26 NA: The test sponsor attests, as of date of publication, that CVE-2017-5754 (Meltdown) is mitigated in the system as tested and documented.
