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. tuned-adm profile was set to virtual-host using 'tuned-adm profile virtual-host' Environment Variables Notes --------------------------- Environment variables set by runcpu before the start of the run: GOMP_CPU_AFFINITY = "0-83" LD_LIBRARY_PATH = "/home/cpu2017/amd_speed_aocc500_znver5_A_lib/lib:/home/cpu2017/amd_speed_aocc500_znver5_A_lib/lib32:" LIBOMP_NUM_HIDDEN_HELPER_THREADS = "0" MALLOC_CONF = "retain:true" OMP_DYNAMIC = "false" OMP_SCHEDULE = "static" OMP_STACKSIZE = "128M" OMP_THREAD_LIMIT = "84" Environment variables set by runcpu during the 621.wrf_s peak run: GOMP_CPU_AFFINITY = "0-41" Environment variables set by runcpu during the 627.cam4_s peak run: GOMP_CPU_AFFINITY = "0-83" Environment variables set by runcpu during the 628.pop2_s peak run: GOMP_CPU_AFFINITY = "0-41" Environment variables set by runcpu during the 654.roms_s peak run: GOMP_CPU_AFFINITY = "0-83" General Notes ------------- Binaries were compiled on a system with 2x AMD EPYC 9D64 CPU + 500GiB Memory using Ubuntu 22.04 NA: The test sponsor attests, as of date of publication, that CVE-2017-5754 (Meltdown) is mitigated in the system as tested and documented.
