Binaries were built using Intel oneAPI 2026.0 compilers.
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.
Stack size set to unlimited using "ulimit -s unlimited".
Environment variables set by runcpu before the start of the run:
LD_LIBRARY_PATH = "/home/speccpu2017/lib/intel64"
MALLOC_CONF = "retain:true"
Binaries compiled on a system with 2x Intel Xeon processors + 1 TB RAM
memory using Red Hat Enterprise Linux 10.1
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.
Transparent Huge Pages enabled with:
echo always > /sys/kernel/mm/transparent_hugepage/enabled
jemalloc, a general purpose malloc implementation
Built with the Red Hat Enterprise Linux 10.1 (Coughlan), and Intel oneAPI 2026.0 icx/icpx compiler.
