Further system related information:

- Spruce Knob utilizes the TORQUE/PBS resource manager to manage compute
   resources.

    To run an interactive shell, issue:
          qsub -I -q queue_name

    To submit a batch job, issue:       qsub job_script.sh
    To show all queued jobs, issue:     showq or qstat
    To check a job status:              checkjob <jobId>
    To kill a queued job, issue:        canceljob <jobId>

    Example PBS job scripts are located at:
    http://wiki.hpc.wvu.edu/hpc_wiki/index.php/Sample_Job_Scripts

    The following man pages provide helpful pbs information:
        man pbs_resources_linux (How-to request cluster resources)
        man qsub
        man qstat

- Spruce Knob utilizes Environment Modules to help manage different software
   packages available on the cluster.  "module avail" shows the available
   modules.

- Spruce has two file systems available to users:
   - $HOME (permanent storage that is backed up via snapshots, 10GB Limit)
   - $SCRATCH (temporary storage that is NOT backed up, current allocation 130 
     TB)

- Please acknowledge use of this Super Computing System (Spruce Knob) at WVU,
   which are funded in part by the National Science Foundation EPSCoR
   Research Infrastructure Improvement Cooperative Agreement #1003907, the
   state of West Virginia (WVEPSCoR via the Higher Education Policy Commission)
   and WVU, in your publications produced using these resources.
