Virtual Desktop (VDI) through Open OnDemand


A new graphical desktop system using Open OnDemand replaces NX/NoMachine for FASRC users.

The new portal provides a browser based interface to the cluster. From the portal you will be able to :

  • browse your files
  • check the status of your jobs
  • submit new batch jobs
  • run remote desktop sessions as part of a compute job on our remote_desktop dedicated partition
  • run other interactive applications like for example Rstudio sessions or Jupyter notebooks

To access the portal you will need to be logged to the FASRC VPN and have cluster access, which you can request via Portal.

How to connect to the VDI portal:

    1. Make sure you are connected to the FASRC VPN.
      Note: When connecting to the VPN, cluster users should connect to the VPN using the @fasrc realm, while NCF users please make sure you are in the @ncf realm
    2. Point your browser to
      Note: NCF users should use
      Safari and Internet Explorer might work for some of the apps in the portal, but are not fully supported. We recommend to use Chrome or Firefox
    3. Enter your RC credentials into the authentication form.authentication to ondemand
    4. Upon successful authentication you will land on the main dashboard.  Please note that the first time you log in the portal might take some time to return.

Quick Tour of the Dashboard:

On the dashboard you will see displayed the Message of the Day – with pointers to our documentation and other important information – and several menus to access the different Apps for File Browsing, Job management and Interactive Computing.

  • Files:
    The File Menu contains a link to open in another tab a File browser that will show you files in your Home folder. See further details here (link will be provided shortly).
  • Jobs:
    This Menu offers two Apps, Active Jobs (ink to specific doc will be provided shortly) will allow you to check the status of your current jobs, while Job Composer (ink to specific doc will be provided shortly) will allow you to edit and submit new jobs through the portal.
  • Clusters:
    The App “O3 Shell Access” will allow you to open a shell terminal in one of the login nodes
    Note: you might be prompted for password and second factor.
  • Interactive Apps:
    This is the Menu where all the Apps for Interactive sessions are contained.  A detailed description of the currently available Apps can be found at this page.
    NCF users should refer to this documentation 
    Please note that the exact content of the menu might vary depending on your user profile and what software you have access to. For example the icon for launching Comsol will be visible only to SEAS users, being the license for that software limited to SEAS.
    Clicking on each of the Apps will bring you to a form to schedule the job and connect to the remote session directly in your browser.
  • My Interactive sessions:
    You will find here all your currently open interactive Apps and you will be able to reconnect to the sessions from here.
  • Help:
    This menu provides links to contact user support and to reset your FASRC password.
    You will also be able to restart the web server that serves your dashboard (only needed for developers and advanced users)
