Submit Notes
The numactl mechanism was used to bind copies to processors. The config file option 'submit' was used to generate numactl commands to bind each copy to a specific processor. For details, please see the config file.
Operating System Notes
Stack size set to unlimited using "ulimit -s unlimited"
Environment Variables Notes
Environment variables set by runcpu before the start of the run: LD_LIBRARY_PATH = "/root/cpu2026/lib" MALLOC_CONF = "retain:true"
General Notes
Binaries compiled on a system with 2x Intel Xeon Platinum 8280M CPU + 384GB RAM memory using CentOS Stream 9. Transparent Huge Pages enabled by default Prior to runcpu invocation Filesystem page cache synced and cleared with: sync; echo 3> /proc/sys/vm/drop_caches runcpu command invoked through numactl i.e.: numactl --interleave=all runcpu <etc> NA: The test sponsor attests, as of date of publication, that CVE-2017-5754 (Meltdown) is mitigated in the system as tested and documented. Yes: The test sponsor attests, as of date of publication, that CVE-2017-5753 (Spectre variant 1) is mitigated in the system as tested and documented. Yes: The test sponsor attests, as of date of publication, that CVE-2017-5715 (Spectre variant 2) is mitigated in the system as tested and documented.
