Testsuite Machines

This page contains notes and instructions for people running the ET testsuites on various different machines. If you have experience running testsuites on a machine which is not listed here, please consider adding some information which might help others (or yourself!) in future.

General

To check out the ET, follow the instructions at http://einsteintoolkit.org/download/ under "Current development version".

Now configure simfactory:

 cd Cactus
 cp simfactory/etc/defs.local.ini.simple simfactory/etc/defs.local.ini
 nano simfactory/etc/defs.local.ini

Edit defs.local.ini and replace

 YOUR_LOGIN with your username
 YOUR@EMAIL.ADDRESS with your usual email address
 YOUR_ALLOCATION with your project allocation
 YOUR_THORNLIST with manifest/einsteintoolkit.th

See the machine-specific notes below for any additional steps for each machine.

 sim sync <machine>
 sim login <machine>
 sim build
 sim create-submit ettests_1proc --testsuite --procs <N> --num-threads <N> --walltime 3:00:00
 sim create-submit ettests_2proc --testsuite --procs <N> --num-threads <N/2> --walltime 3:00:00

Replace <N> and <N/2> with the number of cores on each node, and half of this, respectively, for the machine you are using. Remember that "procs" here means "cores" and "num-threads" means "number of threads per process". The idea is to use a full node, i.e. all the cores, and then either one or two MPI processes.

When the jobs have finished, you should have the summary.log files in

 <simulations>/ettests_1proc/output-0000/TEST/sim/summary.log
 <simulations>/ettests_2proc/output-0000/TEST/sim/summary.log

Update the testsuite status page by adding the log files to the release-info repository:

 svn checkout https://svn.einsteintoolkit.org/www/release-info
 cd release-info
 scp machine:<simulations>/ettests_1proc/output-0000/TEST/sim/summary.log <machine>__1_<N>.log
 scp machine:<simulations>/ettests_2proc/output-0000/TEST/sim/summary.log <machine>__2_<N/2>.log
 svn commit <machine>*.log

To re-run the tests with an updated checkout, run the GetComponents command above with the --update flag, rebuild, delete the "ettests_*" simulations, and resubmit the simulations.
