You’re there doing the work.

Suitable for developing and testing over a few hours.

You’ll only use the reservation for this (and/or other) workshop.

Once you have an account you typically do not need it.

But there are use cases when we can create a specific reservation for you.

Which itself might require a partition to be defined if you’re using a GPU node (more about that later).
