A portable test suite for software installations, using ReFrame

• install ReFrame >=4.0

• install the test suite using

pip install git+https://github.com/EESSI/test-suite.git

Alternatively, you can clone the repository

git clone [email protected]:EESSI/test-suite.git

and set your PYTHONPATH so that it includes the eessi/reframe directory from the repository.

• create a site configuration file

  • should look similar to test-suite/eessi/reframe/config/settings_example.py

• run the tests

  the example below runs a gromacs simulation using GROMACS modules available in the system, in combination with all available system:partitions as defined in the site config file

module load ReFrame/4.0.1

eessiroot=<path_to_test-suite>
eessihome=$eessiroot/eessi/reframe

PYTHONPATH=$PYTHONPATH:$EBROOTREFRAME:$eessihome reframe \
    -C <path_to_site_config_file> \
    -c $eessihome/eessi_checks/applications/ \
    -t CI -t 1_node \
    -r --performance-report

• running GPU jobs in GPU nodes

  • add feature gpu to the GPU partitions

• running non-GPU jobs in non-GPU nodes

  • add feature cpu to the non-GPU partitions

• running GPU jobs and non-GPU jobs on gpu nodes

  • add both features cpu and gpu to the GPU partitions

  'features': ['cpu', 'gpu'],
  

• setting the number of GPUS per node for a partition:

  'access': ['-p <partition_name>'],
  'devices': [
      {'type': 'gpu', 'num_devices': <x>}
  ],
  

• requesting GPUs per node for a partition:

  'resources': [
      {
          'name': '_rfm_gpu',
          'options': ['--gpus-per-node={num_gpus_per_node}'],
      }
  ],
  

• specifying modules

  • --setvar modules=<modulename>

• specifying systems:partitions

  • --setvar valid_systems=<comma-separated-list>

• overriding tasks, cpus, gpus

  • --setvar num_tasks_per_node=<x>
  • --setvar num_cpus_per_task=<y>
  • --setvar num_gpus_per_node=<x>

• setting additional environment variables

  • --setvar env_vars=<envar>:<value>

If you want to install the EESSI test suite from a branch, you can use

pip install git+https://github.com/EESSI/test-suite.git@branchname

This also works on forked repositories, e.g.

pip install git+https://github.com/<someuser>/test-suite.git@branchname

making it an easy way of testing PRs.
