    "[SLURM's PAM module is the] coolest thing since the invention of UNIX...
    We now can control who can log into [compute nodes] or at least can control
    which ones to allow logging into.  This will be a tremendous help for users
    who are developing their apps."

    "As a result of our critical need to run very large, massively parallel jobs
    on thousands of processors and to do so in a cost effective way, LLNL,
    Hewlett-Packard and Linux NetworX researched and developed, over a period of
    years, a resource management tool that would optimize our workload through
    our computers. Today our largest IBM computers, BlueGene/L and Purple, ranked
    #1 and #3 respectively on the November 2005 Top500 list, use SLURM instead
    of IBM's LoadLeveler. This decision reduces large job launch times from tens
    of minutes with LoadLeveler to seconds using SLURM. This effectivley provides
    us with millions of dollars with of additional compute resources without
    additional cost.  It also allows our computational scientists to use their
    time more effectively.  SLURM is scalable to very large numbers of processors,
    another essential ingredient for use at LLNL. This means larger computer
    systems can be used than otherwise possible with a commensurate increase in
    the scale of problems that can be solved. SLURM's scalability has eliminated
    resource management from being a concern for computers of any foreseeable
    size."

    "The new system provides us with greater capacity to run high performance
    message passing parallel applications.  We are very happy with the
    performance of the system and the integration of components provided in
    the HP XC cluster software."
