DCV (NICE Desktop Cloud Visualization)

Summary

Step by step guide to using visualization on the cluster with DCV.

Body

Nice DCV

NICE  Desktop Cloud Visualization (DCV) is a high-performant Remote 3D technology enabling Technical Computing users seamless remote access to 2D/3D interactive desktops to SDSU research computing resources through your web browser.  In short, DCV provides a better experience for interactive modeling than traditional VNC.

SDSU currently uses DCV on three (3) systems tied to research on the cluster.  These systems are Dune, Iris (ResGPU001), and ResVis001.  Research computing currently has 12 licenses available for use on these systems.  You will need VPN access, or Cloudapps, to use DCV from off campus locations.

Using DCV on SDSU Systems

First, ssh into one of the systems listed above:

To initiate a DCV session, simply type dcv create-session session_name where session_name is a name of your choice.  I use newsession for my session name below:

It will look like nothing happened but you can list your newly created session by using dcv list-sessions:

From here, you need to open a web browser to https://iris.jacks.local:8443/#session_name where session_name is the name you see when you list your sessions. Replace the server name with the name of the server you are connecting to.  When you open the browser, accept the security risk and continue.  Here you will be asked to sign in.  Use your SDSU credentials (the same you used to sign into the server) to finish authentication.

Upon sign in, you will be prompted for your password again.  Enter that password and you should now have access to the server resources through your web browser.

 

Closing your Session

Because we are limited by licensing constraints, we encourage you to close your session when you have completed your work.  To do so, exit your DCV web session and open up a terminal to the server you were using.  From there, simply type dcv close-session session_name, for example, dcv close-session newsession.
