Submit Notes

The config file option 'submit' was used.
'numactl' was used to bind copies to the cores.
See the configuration file for details.
Mitigation notes:
gather_data_sampling: Not affected; itlb_multihit: Not affected; l1tf: Not affected;
mds: Not affected; meltdown: Not affected; mmio_stale_data: Not affected;
reg_file_data_sampling: Not affected; retbleed: Not affected; spec_rstack_overflow: Not affected;
spec_store_bypass: Mitigation: Speculative Store Bypass disabled via prctl and seccomp;
spectre_v1: Mitigation: usercopy/swapgs barriers and __user pointer sanitization;
spectre_v2: Mitigation: Enhanced / Automatic IBRS; IBPB: conditional; STIBP: always-on;
srdbs: Not affected; tsx_async_abort: Not affected.

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 <etc>

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.

Environment Variables Notes

Environment variables set by runcpu before the start of the run:
GOMP_CPU_AFFINITY = "0-255"
LD_LIBRARY_PATH =
     "/home/speccpu/amd_speed_aocc500_znver5_A_lib/lib:/home/speccpu/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 = "256"
