Required Training

Once your account has been approved, you will need to complete the following training sessions to continue using the ACCRE cluster. ACCRE requires that all new users complete the training within two months of receiving their accounts.

All intro courses (Unix, Cluster, Slurm) have been moved over to REDCap and are available on demand at the links below. Each course contains a series of videos with multiple choice questions for each video.

If you are unable to access the course, please fill out a help desk ticket and we can help you out.

Previously offered training sessions

Here are slide decks for training sessions that were previously offered by ACCRE. They are included here for reference and are not required to use ACCRE. Some of this information may be out of date (e.g. setpkgs was the package manager used by ACCRE many years ago, and has been replaced with Lmod).
