• Faculty can use the HPC Account Request Form to request accounts for themselves, their student assistants and for non-KSU collaborators. 

  • This usually means that you are not connected through the VPN properly.  Make sure that the Global Protect shows as connected and that the vpn-groups.kennesaw.edu portal is selected.

  • Please contact Tom Boyle (x6180 or tboyle@kennesaw.edu) to discuss the needs of you and your collaborators and schedule a training session.

  • Once you have a connection through the VPN (vpn-groups portal), you will need to use an SSH program.  Mac users can make use of the Terminal.app.  Windows users can use Putty or Windows PowerShell.   'ssh NetID_username@hpc.kennesaw.edu'

    For those wanting to utilize an XWindows session:

    • Windows: ssh -X NetID@hpc.kennesaw.edu
    • Mac:  ssh -Y  NetID@hpc.kennesaw.edu
  • HPC users can request software using the HPC Software Request Form

  • Example: to have MATLAB load into your environemnt whenever you start a new session, use $ module initadd MATLAB

    1. Use a graphical file transfer application that supports SFTP (via SSH)
      Example: Download cyberduck for Mac or Win at https://cyberduck.io 
    2. From within a local terminal, use the scp command
      Example: scp C:\localfile.txt NetID@hpc:/data/home/your_NetID/
  • There are different file formats that can be 'unzipped':

    • gunzip will extract the contents of .gz files.
    • unzip will extract the contents of .zip files.
    • tar -xvf will extract the contents of .tar.gz and .tar.bz2 files.
  • If connected, use nano within a terminal session or move files to and from your workstation and use an editor locally.

  • Yes, the cluster currently has two nodes, each with 4 P100 NVIDIA cards.  A graphical Processing Unit (GPU) is hardware specifically designed to perform graphics related tasks efficiently.  Some software can be made to use GPUs for general purpose computing.

  • The KSU cluster has three major queues:

    • batch - this is the default queue and if comprised of only CPU nodes.
    • himem - this queue has one CPU node with 1 TB of RAM
    • gpu - this queue has nodes with GPU capabilities
  • From the command line:
    qstat - Show status of PBS batch jobs
    showq - Displays information about active, eligible, blocked and completed jobs.

  • While there is no limit on the number of jobs, each user is limited by the total number of cores they can use concurrently.  (480 cores, under heavy utilization 320 cores).  Any jobs beyond the limit will be queued to run as soon as your other jobs complete and resources are available.

  • Walltime is the actual time an application runs, as in timer for the clock on the wall.  The walltime is a parameter that a user provides in their job submission script.

  • This can happen when transferring files from system to system and the end of line character is now what is expected for Linux.  A simple thing to try:
         $ dos2unix name_of_your_file
