OPTIMUM HPC cluster

Welcome to OPTIMUM HPC cluster at EOAS (UBC)!

Requesting access

First, please, subscribe to EOAS Slack Team.

Then, via the above Slack, direct-message Henryk Modzelewski and provide the following information:

  1. Everybody:
    1. Your preferable user ID (likely your EOAS user ID),
    2. Your e-mail address for correspondence from the cluster (job notifications, etc ...),
    3. Whether you are faculty or not.
  2. And non-faculty (students, PDFs, RAs, etc ...):
    1. Group ID, i.e. user ID of your faculty supervisor,
    2. E-mail address of your faculty supervisor.

Once your OPTIMUM account is set up, you will get your initial password. You can change it using yppasswd command from any login node.

Accessing OPTIMUM

Remote login front-end: optimum.eos.ubc.ca

  • You can access OPTIMUM only from computers on UBC network
  • You will need a SSH client installed on your connecting computer

Login examples:

  • ssh your_user_id@optimum.eos.ubc.ca
  • ssh -Y your_user_id@optimum.eos.ubc.ca (with X11 forwarding)
  • ssh -l your_user_id optimum.eos.ubc.ca
  • ssh -Y -l your_user_id optimum.eos.ubc.ca (with X11 forwarding)

Note:

  • while logging in using above examples, you will be automatically redirected to one of OPTIMUM's head nodes, e.g. delta or sigma
  • the users' logins are going to be automatically balanced between login hosts
  • avoid using directly the explicit host name like delta or sigma, so that the load balancing has a chance to work properly

Documentation

Check the menu on the left sidebar for more information. It will be useful, if you at least browse through those even before you login to OPTIMUM for the first time.
