Jupyter Lab, on demand.

JupyterHub runs on the head node and lets any provisioned HPC user launch a real Jupyter Lab server on a compute node — no manual environment setup, no SSH tunnelling.

  1. Log in

    Go to uhpc.unam.na/jupyter/ and sign in with your portal password (the same one used to log into the user portal).

  2. Launch a server

    Click through to start a session. Behind the scenes this submits a PBS job on the stampede queue for you — spawning can take a minute or two while it waits for a free node.

  3. Work in the notebook

    Once it opens, you have a full Jupyter Lab interface running on a compute node, not the shared login node. You can confirm this yourself by running !hostname in a cell — it should print a compute node's name (e.g. sp0-04), not the head node's.

Not single sign-on

The portal's "Launch Jupyter Lab" button takes you to JupyterHub's own login page — same password, but a second prompt. It isn't a silently authenticated hop from the portal.

Prefer a full desktop instead?

If you need a GUI application rather than a notebook, see Remote Desktop (VNC).
