Utilities and APIs for interfacing with the Slurm workload manager.
slurmutils is a collection of various utilities that make it easier for you and your friends to interface with the Slurm workload manager, especially if you are orchestrating deployments of new and current Slurm clusters. Gone are the days of seething over incomplete Jinja2 templates. Current utilities shipped in the slurmutils package include:
from slurmutils.editors import ...
slurmconfig
: An editor for slurm.conf configuration files.slurmdbdconfig
: An editor for slurmdbd.conf configuration files.cgroupconfig
: An editor for cgroup.conf configuration files.

Usage
slurmutils.editors
This module provides an API for editing files, and creating new files if they do not exist. Here's some operations you can perform on files using the editors in this module:
slurmconfig
Edit a pre-existing slurm.conf configuration file
from slurmutils.editors import slurmconfig
# Open, edit, and save the slurm.conf file located at _/etc/slurm/slurm.conf_.
with slurmconfig.edit("/etc/slurm/slurm.conf") as config:
del config.inactive_limit
config.max_job_count = 20000
config.proctrack_type = "proctrack/linuxproc"
Add a new node to the slurm.conf file
from slurmutils.editors import slurmconfig
from slurmutils.models import Node
with slurmconfig.edit("/etc/slurm/slurm.conf") as config:
node = Node(
NodeName="batch-[0-25]",
NodeAddr="12.34.56.78",
CPUs=1,
RealMemory=1000,
TmpDisk=10000,
)
config.nodes.update(node.dict())
slurmdbdconfig
Edit a pre-existing slurmdbd.conf configuration file
from slurmutils.editors import slurmdbdconfig
with slurmdbdconfig.edit("/etc/slurm/slurmdbd.conf") as config:
config.archive_usage = "yes"
config.log_file = "/var/spool/slurmdbd.log"
config.debug_flags = ["DB_EVENT", "DB_JOB", "DB_USAGE"]
del config.auth_alt_types
del config.auth_alt_parameters
cgroupconfig
from slurmutils.editors import cgroupconfig
with cgroupconfig.edit("/etc/slurm/cgroup.conf") as config:
config.constrain_cores = "yes"
config.constrain_devices = "yes"
config.constrain_ram_space = "yes"
config.constrain_swap_space = "yes"
