Overview

SeaWulf Desktop provides a full Linux desktop environment running on SeaWulf compute nodes. Interact with the cluster through a graphical interface, run GUI applications, and manage files and terminals โ€” all in a web browser. For some GUI tools it outperforms X11 forwarding.

Getting started

  1. Open the OnDemand portal at sn-ood.seawulf.stonybrook.edu and authenticate with NetID + DUO
  2. Launch via the SeaWulf Desktop icon or Interactive Apps

Launching and running

After clicking Launch, the session progresses Queued โ†’ Starting โ†’ Running, then opens the full desktop in a new browser tab. Authenticate with your NetID password if prompted.

Sharing and terminal access
