Slurm Workload Manager

This is the Slurm Workload Manager. Slurm is an open-source cluster resource management and job scheduling system that strives to be simple, scalable, portable, fault-tolerant, and interconnect agnostic. Slurm currently has been tested only under Linux.

As a cluster resource manager, Slurm provides three key functions. First, it allocates exclusive and/or non-exclusive access to resources (compute nodes) to users for some duration of time so they can perform work. Second, it provides a framework for starting, executing, and monitoring work (normally a parallel job) on the set of allocated nodes. Finally, it arbitrates conflicting requests for resources by managing a queue of pending work.


The official issue tracker for Slurm is at

We welcome code contributions and patches, but we do not accept Pull Requests through Github at this time. Please submit patches as attachments to new bugs under "Contributions" category.


The top-level distribution directory contains this README as well as other high-level documentation files, and the scripts used to configure and build Slurm (see INSTALL). Subdirectories contain the source-code for Slurm as well as a DejaGNU test suite and further documentation. A quick description of the subdirectories of the Slurm distribution follows:

src/ [ Slurm source ]
Slurm source code is further organized into self explanatory subdirectories such as src/api, src/slurmctld, etc.
doc/ [ Slurm documentation ]
The documentation directory contains some latex, html, and ascii text papers, READMEs, and guides. Manual pages for the Slurm commands and configuration files are also under the doc/ directory.
etc/ [ Slurm configuration ]
The etc/ directory contains a sample config file, as well as some scripts useful for running Slurm.
slurm/ [ Slurm include files ]
This directory contains installed include files, such as slurm.h and slurm_errno.h, needed for compiling against the Slurm API.
testsuite/ [ Slurm test suite ]
The testsuite directory contains the framework for a set of DejaGNU and "make check" type tests for Slurm components. There is also an extensive collection of Expect scripts.
auxdir/ [ autotools directory ]
Directory for autotools scripts and files used to configure and build Slurm
contribs/ [ helpful tools outside of Slurm proper ]
Directory for anything that is outside of slurm proper such as a different api or such. To have this build you need to do a make contrib/install-contrib.
