# Download

SLURM source can be downloaded from http://sourceforge.net/projects/slurm/
SLURM has also been packaged for Debian and Ubuntu (both named slurm-llnl).

Other software available for download includes

- PAM Modules (pam_slurm)
  Pluggable Authentication Module (PAM) for restricting access to compute nodes where SLURM performs resource management. Access to the node is restricted to user root and users who have been allocated resources on that node.
  pam_slurm is available for download from https://sourceforge.net/projects/slurm/
  SLURM's PAM module has also been packaged for Debian and Ubuntu (both named libpam-slurm).
- 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
  http://code.google.com/p/slurm-spank-plugins/.
  The current source for the plugins can be checked out of the subversion repository with the following command:
  svn checkout http://slurm-spank-plugins.googlecode.com/svn/trunk/ slurm-plugins
- 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 faciltiy 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. Download the latest source from:
  http://io-watchdog.googlecode.com/files/io-watchdog-0.6.tar.bz2
