Compiler Notes

 Binaries were compiled on a system with 2x Ampere Altra Q80-30 CPU
 chips + 256 GB Memory using CentOS 8.3

 Ampere GCC 10.2.1 is available via
 https://github.com/AmpereComputing/ampere-gcc/releases

Submit Notes

 The config file option 'submit' was used.
 'numactl' was used to bind copies to the cores.

Operating System Notes

 'ulimit -s unlimited' was used to set environment stack size
 Set dirty_ratio=8 to limit dirty cache to 8% of memory
 i.e. echo 8 | sudo tee /proc/sys/vm/dirty_ratio
 Set swappiness=1 to swap only if necessary
 i.e. echo 1 | sudo tee /proc/sys/vm/swappiness
 Set zone_reclaim_mode=1 to free local node memory and avoid remote memory
 i.e. echo 1 | sudo tee /proc/sys/vm/zone_reclaim_mode
 Set drop_caches=3 to reset caches before invoking runcpu
 i.e. echo 3 | sudo tee /proc/sys/vm/drop_caches
 Set numa_balancing=0 to disable automatic numa balancing
 i.e. echo 0 | sudo tee /proc/sys/kernel/numa_balancing
 Switch off all ktune and tuned settings
 i.e. sudo tuned-adm off
 Transparent huge pages set to 'never'
 i.e. sudo bash -c "echo never > /sys/kernel/mm/transparent_hugepage/enabled"

 runcpu command invoked through numactl i.e.
   numactl --interleave=0-3 runcpu

Environment Variables Notes

Environment variables set by runcpu before the start of the run:
LD_LIBRARY_PATH =
     "/home/amptest/ampere_spec2017/jemalloc/install/lib:/home/amptest/ampere
     _spec2017/gcc/install/lib64/:/home/amptest/ampere_spec2017/gcc/install/l

General Notes

 Jemalloc v5.2.1 is available via
 https://github.com/jemalloc/jemalloc/releases/download/5.2.1/jemalloc-5.2.1.tar.bz2
 It was built on CentOS 8.3 using Version 10.2.1 of Ampere GCC with configure options
 --prefix=/home/amptest/jemalloc/install --with-lg-quantum=3

 NA:  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.
 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.
 NA:  The test sponsor attests, as of date of publication, that CVE-2017-5754 (Meltdown)
      is mitigated in the system as tested and documented.
