Repository for ReFrame configuration and tests for EPCC systems.

• configuration/: configuration files for different EPCC systems
• tests/: test library. All tests should, wherever possible, be configured so that they can run on all systems

To run the full suite of tests on ARCHER2, run the following commands:

module load reframe
module load epcc-reframe

epcc-reframe -r

The last command is just a wrapper around ReFrame to call all the tests and use the ARCHER2 configuration. The -r is the run flag in ReFrame.

Alternatively you may only wish to run a subset of tests.

Again load the modules to enable ReFrame.

module load reframe
module load epcc-reframe

To run a specific test

reframe -C ${EPCC_REFRAME_CONFIG} -c *path-to-a-test* -r

To run all tests in a directory:

reframe -C ${EPCC_REFRAME_CONFIG} -c *path-to-a-test-directory* -R -r

Where EPCC_REFRAME_CONFIG is set by the epcc-reframe module and is the path for the ARCHER2 configuration.

The following launchers should be added to the reframe/core/launchers/mpi.py to define launchers for Intel MPI and HPE MPT. Added after the definition for the mpiexec launcher.

@register_launcher('impi')
class MpiexecLauncher(JobLauncher):
    def command(self, job):
        return ['mpirun', '-ppn', str(job.num_tasks_per_node), '-n', str(job.num_tasks)]

@register_launcher('hpempt')
class MpiexecLauncher(JobLauncher):
    def command(self, job):
        return ['mpiexec_mpt', '-ppn', str(job.num_tasks_per_node), '-n', str(job.num_tasks)]
# HPE MPT mpiexec_mpt has to be used within a job (will not work with 'local' scheduler)
