Comsol Server Workflow

Last edited by Eric Franz

Comsol Server VNC Session

  1. Connect to

    oakley.osc.edu

    using your favorite SSH client and your AweSim account username/password.

  2. Run the Comsol Server OSC script:

    $ ~jnicklas/altasim/comsol_script 

Welcome to a simple OSC COMSOL server batch submission script.

Make sure you are in the working directory with your data files.
  Current path: /nfs/17/username/path/to/project/files

1. COMSOL Server (single node)
Choose (default 1):

  3. Choose option 1 for a VNC session

    • #1 - Launches Comsol Server with a Firefox browser on a single compute node on Oakley (12 cores).

    Further details may need to be provided for specific option chosen above:

    • resolution - Specify the resolution you want the VNC session to run in WxH (e.g., 1920x1200)
    • # hours - This is the upper limit of time the job will run. If you go beyond this time requested, the job will die unexpectedly.

  4. Wait until you receive an email with the location of a file that contains the connection information for the VNC session launched as well as some useful host information.

    Your VNC job has started. The connection information can be found at:

    /nfs/17/username/path/to/project/files/3456195.oak-batch.osc.edu.conn

    A list of the hosts allocated for this job can be found at (used when launching Fluent from Ansys Workbench):

    /nfs/17/username/path/to/project/files/3564940.oak-batch.osc.edu.nodes

    A list of unique hosts are (used for supplying hosts in the CFX-Solver GUI):

    • n0616
    • n0617

  5. Back in your SSH client connected to oakley.osc.edu output the contents of that secure file:

    $ cat /nfs/17/username/path/to/project/files/3456195.oak-batch.osc.edu.conn

Host: n0666.ten.osc.edu
Port: 5901
Pass: 3juRnrx0Mt
Display: 1

username:3juRnrx0Mt:n0666.ten.osc.edu:5901

  6. Use this information in your VNC client to connect to this session through SSH tunneling

  7. You will be greeted with a Firefox browser in the VNC session running the Comsol Server

    Type in your Awesim username and password.

    Then click "Log in to COMSOL Server".
