EPCC ReFrame

Repository for ReFrame configuration and tests for EPCC systems.

Structure

  • 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

Modifications to ReFrame source

ARCHER2 test execution

Run all tests

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.

Run specific tests

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.

Cirrus support

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)
