Before you run...
Naive use of HPC resources can easily lead to mistakes that disrupt other users. Hence, we ask that you please go over the user manual, guides, phrases and terms, and FAQ to make sure you understand what your code will do in the HPC system before you use LUNARC resources. The HPC Wiki is also a good resource if you want a more thorough explanation of commonly used phrases and terms in the manual.
Don't clog the login node!
The most disruptive mistake that a new HPC user can make is to run resource-intensive code directly as if it were a much smaller task on their own laptop. Be careful what you run outside the SLURM scheduling system! If you run a demanding job directly, either by calling the code file at the command line or through a user interface (JupyterLab for example), it will run on the frontend - the login node - creating a bottleneck that can stall other users' jobs. For any job big enough to be worth running on a HPC system, you must create a job script and run your code by calling the job script with sbatch. For more on job scripts, refer to the section of the manual on submitting jobs.
Remember that repeated disruptive misuse of the frontend is a violation of the terms and conditions of your NAISS user agreement, and may result in the suspension or termination of your account.
Training through NAISS
LUNARC and NAISS offer a variety of training and development courses, including several recurring workshops targetting users new to high performance computing. We highly recommend that all new users check on SUPR that they are signed up for the NAISS Training Newsletter. To check your subscription status, log into SUPR and click the Groups tab. If you are signed up for the newletter (which typically happens automatically upon creating an account), it will appear under the heading "Group You Manage or Belong To". Otherwise, you should be able to find "NAISS-training-subscribe" under the "Groups You Can Join" heading.
You can also find the list of upcoming events on the LUNARC website under "Learning More".
