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 ...

• acctgatherconfig: An editor for acct_gather.conf configuration files.
• cgroupconfig: An editor for cgroup.conf configuration files.
• gresconfig: An editor for gres.conf configuration files.
• slurmconfig: An editor for slurm.conf configuration files.
• slurmdbdconfig: An editor for slurmdbd.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:

acctgatherconfig

Edit a pre-existing acct_gather.conf configuration file

from slurmutils.editors import acctgatherconfig

with acctgatherconfig.edit("/etc/slurm/acct_gather.conf") as config:
    config.profile_influx_db_database = "test_acct_gather_db"
    config.profile_influx_db_default = ["NONE"]
    config.profile_influx_db_host = "testhostname1"
    config.profile_influx_db_pass = "testpassword1"
    config.profile_influx_dbrt_policy = "testpolicy1"
    config.profile_influx_db_user = "testuser1"
    config.profile_influx_db_timeout = "20"

cgroupconfig

Edit a pre-existing cgroup.conf configuration file

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"

gresconfig

Edit a pre-existing gres.conf configuration file

from slurmutils.editors import gresconfig
from slurmutils.models import GRESName, GRESNode

with gresconfig.edit("/etc/slurm/gres.conf") as config:
    new_gres = GRESName(
            Name="gpu",
            Type="epyc",
            File="/dev/amd4",
            Cores=["0", "1"],
        )
    new_node = GRESNode(
        NodeName="juju-abc654-[1-20]",
        Name="gpu",
        Type="epyc",
        File="/dev/amd[0-3]",
        Count="12G",
    )
    config.auto_detect = "rsmi"
    config.names[new_gres.name] = [new_gres]
    config.nodes[new_node.node_name] = [new_node]

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
