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

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

Running The Long Time Benchmark

bin/runspec -c intel2 --action=run --define external --rate 24 --define smt \
--define cores=24 --define physicalfirst --define invoke_with_interleave \
--define drop_caches --define THP_enabled -T all --reportable -o all fp

Minimal Install On CentOS 7

Spec CPU 2006 need to be purchased.

Dependencies

yum install dmidecode vim screen tree zsh rsync openssh-clients wget
yum install gcc-gfortran.x86_64 numactl libgfortran.i686 libgfortran.x86_64 \

Configuration

useradd -s /bin/bash -U -m -c HPC -d /home/hpc hpc
mkdir /cpu2006
chown hpc:hpc /cpu2006
su - hpc
ssh-keygen

Copy ISO image to /home/hpc/src

mkdir /home/hpc/src
wget ../cpu2006-1.2.iso
mkdir /home/hpc/mnt
mount -o loop /home/hpc/src/cpu2006-1.2.iso /home/hpc/mnt

As user hpc

cd /home/hpc/mnt/
./install.sh

Enter the directory you wish to install to (e.g. /usr/cpu2006)

/cpu2006
yes

As root

umount /home/hpc/mnt

Power Measurement

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

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