Visit on Cooley

Getting Started

On your local machine:

  • Download and install VisIt (https://wci.llnl.gov/simulation/computer-codes/visit/downloads) The most recent version installed on Cooley is 3.0.1. Other supported versions on Cooley include 3.0.0 and 2.13.2.
  • Install the Cooley Host Profile.
    • You should be prompted to install desired host profiles the first time you run VisIt after installing it.  You can also get to it from the main menu under Options->Host profiles and configuration setup...
    • Choose the Argonne National Laboratory (ANL) network.

Running VisIt in Interactive Mode

  • Start up VisIt on your local machine (Version 3.0.1, 3.0.0, or 2.13.2)
  • Click File -> Open File and choose "ANL Cooley" from the "Host" dropdown
  • You'll be prompted for your password; enter your Cryptocard response (with PIN)
  • When you open a selected file, it will launch a job on Cooley
    • Use the Parallel launch profile, which will submit a job to run the VisIt server on Cooley's visualization nodes
    • You will need to specify the "Bank" (Project) to use when VisIt submits jobs to the queue on Cooley.  Specify a project in the Options box.
    • If your environment doesn't get sourced correctly with non-interactive SSH, you can set the default project to use under Options -> Host profiles 
    • Note: Don't change the contents of the "Machine file" field (it should be $COBALT_NODEFILE)
    • Note: The default Launch Profile is set to serial.  Do not change this default setting.
    • If you'd like to change other job parameters (like the number of processes, nodes, and walltime), you can do so.
    • If you'd like these changes to be used as your default, be sure to save them using Save Settings under the Options menu.

Running VisIt in Batch Mode

  • Edit your .soft.cooley file to include the "@visit" key before the "@default" line 
  • When running VisIt in batch mode on Cooley, the default version is 3.0.1
  • If you need a different version, you can specify this as a command line option using "-v <version number>" (versions 3.0.0 and 2.13.2 are also supported)
