  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).

  - 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
  https://github.com/grondo/slurm-spank-plugins.
  A SPANK plugin called "spunnel" to support ssh port forwarding is available from Harvard University. It can be downloaded from the spunnel repository.

  STUBL home page.
  pbs2sbatch
    Converts PBS directives to equivalent Slurm sbatch directives. Accommodates old UB CCR-specific PBS tags like IB1, IB2, etc.
  pbs2slurm
    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.
  slurmbf
    Analogous to the PBS "showbf -S" command.
  snodes
    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.
  sqstat
    A customized version of squeue that produces output analogous to the PBS qstat and xqstat commands (requires clush).
  fisbatch
    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).
  sranks
    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.
  sqelp
    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.
  sjeff
    Determines the efficiency of one or more running jobs. Inefficient jobs are high-lighted in red text (requires clush).
  sueff
    Determines the overall efficiency of the running jobs of one or more users. Users that are inefficient are highlighted in red text (requires clush).
  yasqr
    Yet Another Squeue Replacement. Fixes squeue bugs in earlier versions of Slurm.
  sgetscr
    Retrieves the Slurm/sbatch script and environment files for a job that is queued or running.
  snacct
    Retrieves Slurm accounting information for a given node and for a given period of time.
  suacct
    Retrieves Slurm accounting information for a given user's jobs for a given period of time.
  slist
    Retrieves Slurm accounting and node information for a running or completed job (requires clush).
  slogs
    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.
- Slurmmon
  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.
  Slurmmon code
- 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:
  - Graphing sdiag with Graphite
  - A collection of custom diamond collectors to gather various Slurm statistics
  - Collectd (for use with jobmetrics)
- MSlurm
  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.
