 - [`devices`](https://reframe-hpc.readthedocs.io/en/stable/config_reference.html#config.systems.partitions.devices): This field specifies information on devices (for example) present in the partition. Device types are standardized in the EESSI test suite in the [`eessi.testsuite.constants.DEVICE_TYPES`](https://github.com/EESSI/test-suite/blob/main/eessi/testsuite/constants.py) dictionary. This is used by the EESSI test suite to determine how many of these devices it can/should use per node.
