The Industry Cluster Desktop App launches an interactive desktop session on one of the Industry cluster nodes.  You will not be able to use this app unless you're an industry business partner and see the 'industry' partition listed as a QOS when you run the 'slimits' command.


Users with access to the Industry cluster scavenger partition can not utilize that through an OnDemand interactive session.





  1. Slurm Account: Your default Slurm account will be used if nothing else is entered.  To see what Slurm accounts you have access to, use the 'slimits' command in a terminal window.  
  2. Number of hours:  This cluster has a max walltime of 72 hours.  
  3. Number of nodes: Only select more than one node if you're sure your program can run on multiple nodes.


In this example, we've started up an Industry Cluster Desktop.  Once you click the Launch button, you will be redirected to the session information where you can see the status of the job.  This one is queued:



If you have elected to receive an email when your job starts, you can leave the CCR OnDemand portal until the email arrives and then log back in to open your session.  


When a session is ready to launch, it will look like this in the Interactive Sessions section of OnDemand:


Click on the blue "Launch Industry Cluster Desktop" button and you will see your desktop window on the node you've been allocated:




You are now logged into a visualization session and onto a node in the CCR academic cluster.  You can begin your work!  



If this is your first time starting a remote visualization session, you may be prompted with this pop-up:



Please click "Use default config"



NOTE: If your session starts and does not display a menu or icons on the bottom (as shown in these screenshots), check out this troubleshooting article
