Running

scronjob shows the scrontab for running the MESA test suite. This is a recurring slurm job, which replaces the previous crontab.

• Every 5 minutes, we call launch.sh, which logs a small amount of information about my current overall cluster usage, and then launches MESA test suite runs by calling runMesaTest.sh
• Once per night around 2am, we call runMesaOptional.sh, which just submits the latest commit at the head of main and runs all tests with the optional inlists included.

runMesaTest.sh is a fairly lightweight launching script that sets up the other jobs. It simply sets the relevant environment variables (see mesa_test.sh), fetches the latest commits, and submits installation jobs for any commit that does not yet exist in the $MESA_LOG directory.

Each commit that needs to be installed gets submitted as a slurm job running test-mesa.sh. This does a full MESA checkout and installation, and then submits job arrays for the test suites. The array index ($SLURM_ARRAY_TASK_ID) tells the following scripts which entry from do1_test_source to run.

• star.sh runs an array for all the tests in star/test_suite/do1_test_source
• binary.sh runs an array for all the tests in binary/test_suite/do1_test_source
• astero.sh runs an array for all the tests in astero/test_suite/do1_test_source

cleanup.sh runs after all the test suite jobs have finished. This copies the test suite output (*/test_suite/*/*.txt files) into the relevant $MESA_LOG directories, and then deletes MESA installation for that commit.

Initial Setup and Important Environment Variables

These scripts require that the mesa_test ruby gem is installed and configured to be ready to submit to MESA testhub.

mesa_test.sh contains several important environment variables that help the automated testing scripts run:

• $MESA_GIT: the location of the git mirror that the mesa_test gem is configured to use.
• $MESA_LOG: the location where output from test suite runs gets stored. Crucially, this is the location that gets checked to see if a commit has already been run, or still needs to be run.
• $MESA_TMP: the location that temporary MESA installations are checked out to and installed in.
