Accessing our training cluster

Open a terminal emulator

Windows:     MobaXTerm (free Home Edition)
MacOS:     Terminal
Linux/WSL:     Your usual terminal emulator

SSH into the cluster

Usernames and passwords will be given to you during the Zoom session.

  • Linux, WSL, and MacOS type in your terminal:
$ ssh userxxx@beluu.c3.ca
# enter password (it is blind typing, so you won't see it as you type)
  • Window users:

This demo shows how to use SSH with MobaXterm (for "Remote host" enter: beluu.c3.ca).

Running Julia in a job inside the training cluster

Load the Julia module

To see which versions of Julia are available on the cluster:

$ module avail julia

We will load the latest Julia (julia/1.7.0) which is the default

$ module load julia              # not mentioning any version loads the default

Start an interactive job 

$ salloc --time=01:00:00 --mem=7482

Launch Julia

Finally, we can launch the Julia REPL by running the `julia` command:

$ julia

JupyterHub access

Log in to the JupyterHub on our training cluster

For this course, we will also use a temporary JupyterHub. Here is how to log in:

  • Go to https://beluu.c3.ca,
  • Sign in with the username & password you just got,
  • Set the server options according to the image below,

These are the only values that you should edit:
Change the time to 3.0

Make sure the Memobry is set to 7482
Make sure the interface is set to JupyterLab

  • Press start.

Note that, unlike other JupyterHubs you might have used (e.g. Syzygy ), this JupyterHub is not permanent and can only be used for this course.

Start a Julia notebook

To start a Jupyter notebook with the Julia kernel, click on the button "Julia 1.5.2" in the "Notebook" section (top row of buttons).
