Who Can Access the ELSA HPC Cluster

Currently, anyone with TCNJ login and password can activate their account on the cluster. This may change in the future if there is contention for the resource.

How Do I "Activate" My TCNJ Account on the Cluster

Activating your account sets up some critical files that are needed before you can use the cluster. This only need to be done once. It creates your home directory which is a space for you to store your personal files, programs and application configuration files. It also creates SSH keys which are used by to encrypt network traffic between computers.

To begin point your browser to the URL https://elsa.hpc.tcnj.edu:4200/. This needs to be done from an on-campus computer (wired or wireless) or from an off-campus computer utilizing the TCNJ VPN.

  1. At the elsa login: prompt, enter your TCNJ username
  2. At the password: prompt, enter your TCNJ password (the same one you use to access email, Canvas, etc.)
  3. Once successful, you should see messages similar to the following (this assumes you haven't set up your account previously).
  4. At the $ prompt, type exit and close the browser window/tab.

You are now ready to access your cluster account using Open OnDemand or an SSH shell.

Accessing the Cluster via Open OnDemand

Once you have activated your account, you can use a web portal to access common function on the cluster. This web portal is called Open OnDemand and can be access at the URL https://ondemand.hpc.tcnj.edu/. Use your existing TCNJ login and password when prompted. To fully logout of Open OnDemand, you must fully quit your browser.
