Abstractions for managing Slurm operations via snap or systemd.
This library contains manager classes that provide high-level interfaces for managing Slurm operations within charmed operators.
Note
This charm library depends on the charms.operator_libs_linux.v0.apt charm library, which can
be imported by running charmcraft fetch-lib charms.operator_libs_linux.v0.apt.
Example Usage
Managing the slurmctld service
The SlurmctldManager class manages the operations of the Slurm controller service.
You can pass the boolean keyword argument snap=True or snap=False to instruct
SlurmctldManager to either use the Slurm snap package or Debian package respectively.
from charms.hpc_libs.v0.slurm_ops import SlurmctldManager
class ApplicationCharm(CharmBase):
# Application charm that needs to use the Slurm snap.
def __init__(self, *args, **kwargs) -> None:
super().__init__(*args, **kwargs)
self._slurmctld = SlurmctldManager(snap=True)
self.framework.observe(self.on.install, self._on_install)
def _on_install(self, _) -> None:
self._slurmctld.install()
self.unit.set_workload_version(self._slurmctld.version())
with self._slurmctld.config.edit() as config:
config.cluster_name = "cluster"
