    "hold <job_id>" when executed by a SLURM administrator can only be released
    by a SLURM administrator and not the job owner.

   the exit code of the job script (or salloc) while derived_ec contains the

-- Added SLURM_JOB_EXIT_CODE and SLURM_JOB_DERIVED_EC variables to the
   EpilogSlurmctld environment

  notes.

better support for new cross-cluster support.  Works from all types of clusters for most commands.  The actual commands need to change now to make it better.

    sockets_per_node, min_cores to cores_per_socket, and min_threads to
    threads_per_core (the values are not minimum, but represent the target
    values).

    The default MaxJobCount was changed from 5,000 to 10,000.

framework for handling cross-cluster communication.  Nothing works yet, more most cases all that needs to be added is talking to the database to get where the other clusters are.

    (currrently in the contribs directory, but plan to distribute through
    http://code.google.com/p/slurm-spank-plugins/).

     manage generic resources.

    disable_root_jobs, hidden and root_only fields with a single field called
    "flags" populated with the flags PART_FLAG_DEFAULT, PART_FLAG_NO_ROOT
    PART_FLAG_HIDDEN and/or PART_FLAG_ROOT_ONLY. This is a more flexible
    solution besides making for smaller data structures.

    "scontrol update JobId=# NumNodes=#" or
    "scontrol update JobId=# NodeList=<names>". Subsequent job steps must
    explicitly specify an appropriate node count to work properly.

    daemon's nice value.

    See "man slurm.conf" for details about how these control when slurmctld
    updates its information of which users are in the groups allowed to use
    partitions.

 -- Add support for maximum node count in job step request.
 -- Fix bug in CPU count logic for job step allocation (used count of CPUS per
    node rather than CPUs allocated to the job).

    verify the slurm.conf is the same as the one it is running.  If not an
    error message is displayed.  To silence this message add NO_CONF_HASH
    to DebugFlags in your slurm.conf.

    option of "Alternate" (alternate partition to use for jobs submitted to 
    partitions that are currently in a state of DRAIN or INACTIVE).

   retrieve from the accounting storage db a user's request for job usage or
   machine utilization statistics and charts the results to a browser.

    support writing scheduling events to a separate log file.

    option will allocate one task per core by default. Without this option,
    by default one task will be allocated per thread on nodes with more than
    one ThreadsPerCore configured.
