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
Use updated calc_testjobs_linux.sh
DATA=scaling.xvg
echo -e "# scaling for Hippo\n# numthreads walltime/s" > $DATA
for NSLOTS in `seq 8`; do
echo "-- NSLOTS = $NSLOTS";
../../calc_testjobs_linux.sh -n $NSLOTS walp_octane_NPT_sp_MD \
| awk '/BENCHMARK/ {print $3, $4}' >> $DATA;
done
Note:
- only run this on an empty machine: we are using wall time for timing
