The SPEC CPU 2006 benchmark from the Standard Performance Evaluation Corporation (SPEC) is a proprietary benchmark in use until September 2017. The benchmark suite includes SPECint® benchmarks and SECfp® benchmarks. The SPECint® 2006 benchmark includes 12 different benchmark tests and the SPECfp® 2006 benchmark includes 19 different benchmark tests. It can be used to measure computer speed or throughput.

This benchmark has been superseded by SPEC CPU® 2017, version 1.1.9 as of 2023-03-11.

Some Hints For Intel Clusters

Preparation Before Running

As root:

echo always > /sys/kernel/mm/redhat_transparent_hugepage/enabled
echo 1 > /proc/sys/vm/drop_caches

As user:

cd /cpu2006
source  /opt/intel/bin/compilervars.sh intel64
#source /cm/shared/apps/intel-ics-2013/bin/compilervars.sh intel64
source shrc
ulimit -s unlimited

Power Measurement

An example of a power measurement could be as follows (assuming the power measurement logic is provided in the query script). The content of this script is not provided, as the way the measurement is done is very architecture dependent. The loop queries the power supply every second for 21600 seconds, or 6 hours.

for i in {1..21600}; do ./query $i >> 2013-10-22-1900.log; sleep 1; done
