Running HS06

Running the HEPSPEC-06 benchmark

This article describes the steps that were taken to run the HEPSPEC-06 benchmark on the worker nodes at Nikhef. The procedure is in principle described on the HEPiX web site and some additional information can be found at EGI. However, some modifications were needed to get the benchmark to run.

Procedure

0. Run as root, otherwise the memory queries done by the procedure will fail. Also, you may need to install the package sharutils, as the script expects to find uuencode in its path.

1. Create the base directory for the test

 SPEC=/tmp/benchmark
 mkdir $SPEC

2. Get the benchmark configuration tarball and extract it in the base directory

 cd $SPEC
 tar xzvf spec2k6-2.13.tar.gz

3. Overwrite runspec.sh with this version of runspec.sh

4. Get the SPEC2006 test suite. If you got an NDPF account, you can get cpu2006.tar.bz2. Extract the file

 tar xjvf /tmp/cpu2006.tar.bz2

5. Prepare a result directory in another tree, eg $HOME:

 mkdir /root/myresults

6. To run the test, start a screen session and start the benchmark in it:

 screen
 ./runspec.sh -f /root/myresults -a 32 -d "mynode CentOS 5.9 x86_64 HS06"

7. Wait until the test completed (this may take 4 hours or more, depending on the hardware). The results appear in the specfied results directory:

 head myresults/spec2k6-wn-car-019-20130411-111830/system.txt
