Integration with tests
We could write a script that does the benchmark while running the test. It would even be possible to automatically post it (with the user's consent, of course). — Oli 16:03, 14 November 2008 (UTC)
Scaling
How to run scaling tests/testing methodology:
Use test_scaling.py which in turn uses calc_testjobs_linux.sh.
cd testjobs test_scaling.py NSLOTS
where NSLOTS is the maximum number of available cpus/cores. Results are the files
scaling.xvg # numbers scaling.png # graphs
- Only measures wall time, hence must be run on an empty machine.
- Uses
date +%sso accuracy is limited to seconds. - No repeat runs; results may vary slightly.
Manually: Use updated calc_testjobs_linux.sh
DATA=scaling.xvg
MAXSLOTS=8
echo -e "# scaling for Hippo\n# numthreads walltime/s" > $DATA
for NSLOTS in `seq $MAXSLOTS`; do
echo "-- NSLOTS = $NSLOTS";
../../calc_testjobs_linux.sh -n $NSLOTS walp_octane_NPT_sp_MD \
| awk '/BENCHMARK/ {print $3, $4}' >> $DATA;
done
All the above remarks apply here, too.
