Submit Notes
The config file option 'submit' was used. 'numactl' was used to bind copies to the cores. See the configuration file for details.
Operating System Notes
'ulimit -s unlimited' was used to set environment stack size 'ulimit -l 2097152' was used to set environment locked pages in memory limit runspec command invoked through numactl i.e.: numactl --interleave=all runspec <etc> Set dirty_ratio=8 to limit dirty cache to 8% of memory Set swappiness=1 to swap only if necessary Set zone_reclaim_mode=1 to free local node memory and avoid remote memory sync then drop_caches=3 to reset caches before invoking runcpu Linux governor set to performance with cpupower "cpupower frequency-set -r -g performance" Transparent huge pages were enabled for this run (OS default) Set vm/nr_hugepages=57344 in /etc/sysctl.conf mount -t hugetlbfs nodev /mnt/hugepages
Platform Notes
BIOS Configuration: Thermal Configuration set to Maximum Cooling Performance Determinism set to Power Deterministic Memory Patrol Scrubbing set to Disabled Workload Pofile set to General Throughput Compute Minimum Processor Idle Power Core C-State set to C6 State
General Notes
Environment variables set by runspec before the start of the run: HUGETLB_LIMIT = "896" LD_LIBRARY_PATH = "/home/cpu2006/amd1603-rate-libs-revB/32:/home/cpu2006/amd1603-rate-libs-revB/64" The binaries were built with the x86 Open64 Compiler Suite, which is only available from (and supported by) AMD at http://developer.amd.com/tools-and-sdks/cpu-development/x86-open64-compiler-suite/
