- DRMAA (Distributed Resource Management Application API)
PSNC DRMAA for Slurm is an implementation of Open Grid Forum DRMAA 1.0 (Distributed Resource Management Application API) specification for submission and control of jobs to
Slurm. Using DRMAA, grid applications builders, portal developers and ISVs can use the same high-level API to link their software with different cluster/resource management systems.
There is a variant of PSNC DRMAA providing support for Slurm's --cluster option available from https://github.com/natefoo/slurm-drmaa.
Perl 6 DRMAA bindings are available from https://github.com/scovit/Scheduler-DRMAA.
A Python program used for manipulation of Slurm hostlists including functions such as intersection and difference. Download the code from:
Lua bindings for hostlist functions are also available here:
NOTE: The Lua hostlist functions do not support the bracketed numeric ranges anywhere except at the end of the name (i.e. "tux[0001-0100]" and "rack[0-3]_blade[0-63]" are not supported).

- I/O Watchdog
A facility for monitoring user applications, most notably parallel jobs, for hangs which typically have a side-effect of ceasing all write activity. This facility attempts to monitor all write activity of an application and trigger a set of user-defined actions when write activity as ceased for a configurable period of time. A SPANK plugin is provided for use with Slurm. See the README and man page in the package for more details. https://github.com/grondo/io-watchdog
- MPI versions supported
- Workload Simulator
A Slurm simulator is available to assess various scheduling policies using historic workload data. Under simulation, jobs are not actually executed. Instead, a job execution trace from a real system, or a synthetic trace, are used.
NOTE: This sofware is currently not maintained.
- PAM Module (pam_slurm)
Pluggable Authentication Module (PAM) for restricting access to compute nodes where Slurm performs workload management. Access to the node is restricted to user root and users who have been allocated resources on that node. NOTE: pam_slurm is included within the Slurm distribution. For earlier Slurm versions, pam_slurm is available for download here.
Slurm's PAM module has also been packaged for Debian and Ubuntu (both named libpam-slurm).
- Command wrappers
There is a wrapper for Maui/Moab's showq command here.
- Job Script Generator
- Scripting interfaces
- A Perl interface is included in the Slurm distribution in the contribs/perlapi directory and packaged in the perapi RPM.
- PySlurm is a Python/Pyrex module to interface with Slurm. There is also a Python module to expand and collect hostlist expressions available here.
- Lua may be used to implement a Slurm process tracking plugin. The Lua script available in contribs/lua/protrack.lua implements containers using CPUSETs.
- SPANK Plugins
SPANK provides a very generic interface for stackable plug-ins which may be used to dynamically modify the job launch code in Slurm. SPANK plugins may be built without access to Slurm source code. They need only be compiled against Slurm‘s spank.h header file, added to the SPANK config file plugstack.conf, and they will be loaded at runtime during the next job launch. Thus, the SPANK infrastructure provides administrators and other developers a low cost, low effort ability to dynamically modify the runtime behavior of Slurm job launch. As assortment of SPANK plugins are available from
A SPANK plugin called "spunnel" to support ssh port forwarding is available from Harvard University. It can be downloaded from the spunnel repository.
A set of scripts that leverages Slurm's job completion logging facility in provide information about what jobs were running at any point in the past as well as what resources they used. Download the code from:
- Task Affinity plugins
- Node Health Check
Probably the most comprehensive and lightweight health check tool out there is LBNL Node Health Check. It has integration with Slurm as well as Torque resource managers.

- STUBL (Slurm Tools and UBiLities)
STUBL is a collection of supplemental tools and utility scripts for Slurm.
STUBL home page.
- Converts PBS directives to equivalent Slurm sbatch directives. Accommodates old UB CCR-specific PBS tags like IB1, IB2, etc.
- A script that attempts to convert PBS scripts into corresponding sbatch scripts. It will convert PBS directives as well as PBS environment variables and will insert bash code to create a SLURM_NODEFILE that is consistent with the PBS_NODEFILE.
- Analogous to the PBS "showbf -S" command.
- A customized version of sinfo. Displays node information in an easy-to-interpet format. Filters can be applied to view (1) specific nodes, (2) nodes in a specific partition, or (3) nodes in a specifc state.
- A customized version of squeue that produces output analogous to the PBS qstat and xqstat commands (requires clush).
- Friendly Interactive sbatch. A customized version of sbatch that provides a user-friendly interface to an interactive job with X11 forwarding enabled. It is analogous to the PBS "qsub -I -X" command. This code was adopted from srun.x11 (requires clush).
- A command that lists the overall priorities and associated priority components of queued jobs in ascending order. Top-ranked jobs will be given priority by the scheduler but lower ranked jobs may get slotted in first if they fit into the scheduler's backfill window.
- A customized version of squeue that only prints a double-quote if the information in a column is the same from row to row. Some users find this type of formatting easier to visually digest.
- Determines the efficiency of one or more running jobs. Inefficient jobs are high-lighted in red text (requires clush).
- Determines the overall efficiency of the running jobs of one or more users. Users that are inefficient are highlighted in red text (requires clush).
- Yet Another Squeue Replacement. Fixes squeue bugs in earlier versions of Slurm.
- Retrieves the Slurm/sbatch script and environment files for a job that is queued or running.
- Retrieves Slurm accounting information for a given node and for a given period of time.
- Retrieves Slurm accounting information for a given user's jobs for a given period of time.
- Retrieves Slurm accounting and node information for a running or completed job (requires clush).
- Retrieves resource usage and accounting information for a user or list of users. For each job that was run after the given start date, the following information is gathered from the Slurm accounting logs: Number of CPUs, Start Time, Elapsed Time, Amount of RAM Requested, Average RAM Used, and Max RAM Used.
Prints a consolidated compute node status line, with one line per node including a list of jobs.
Slurmmon is a system for gathering and plotting data about Slurm scheduling and job characteristics. It currently simply sends the data to ganglia, but it includes some custom reports and a web page for an organized summary. It collects all the data from sdiag as well as total counts of running and pending jobs in the system and the maximum such values for any single user. It can also submit probe jobs to various partitions in order to trend the times spent pending in them, which is often a good bellwether of scheduling problems.
- Graphical Sdiag
The sdiag utility is a diagnostic tool that maintains statistics on Slurm's scheduling performance. You can run sdiag periodically or as you modify Slurm's configuration. However if you want a historical view of these statistics, you could save them in a time-series database and graph them over time as performed with this tool:
Such a superstructure for the management of multiple Slurm environments is done with MSlurm. Thereby several Slurm clusters - even across multiple Slurm databases - can run parallel on a Slurm master and can be administered in an easy and elegantly manner.
Some Slurm plugins (burst_buffer/datawarp and power/cray_aries) plugins parse JSON format data. These plugins are designed to make use of the JSON-C library for this purpose. Instructions for the build are as follows:
