The Simple Linux Utility for Resource Management (SLURM) is an open source, fault-tolerant, and highly scalable cluster management and job scheduling system for large and small Linux clusters. The architecture is described here https://computing.llnl.gov/linux/slurm/quickstart.html.

• Installation
  • begins with installing Munge
    • fairly straightforward, build RPMs from tarball
    • installed on head node and all compute nodes
    • copied the munge.key from head node to all compute nodes
  • slum installed from source code with
    • \-\-prefix=/opt/slurm-14 \-\-sysconfdir=/opt/slurm-14/etc
    • launched the configurator web page and set up a simple setup
      • created the openssl key and cert (see slurm web pages)
      • logs to files not mysql for now
      • change some settings in slurm.conf, particularly
        • FirstJObId, MaxJobId
        • MaxJobCount=100000
        • MaxTaskPerNode=65533
        • SRunEpilog/SRunProlog (creates and removes work directories in /scratch/SLUM_JOB_ID)
