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 classes (Unix, Cluster, Slurm) have been moved over to Brightspace. You should receive access to the course on Brightspace as part of your registration (it will be labeled as a “sandbox course”). If you are unable to access the course, please fill out a help desk ticket and we can help you out.
Intro to Unix
This class gives an overview of Unix/Linux operating systems. You may skip this training session if you are already familiar with Linux or Unix.
- Command line execution and shortcuts
- Getting help with commands
- Files and directories, including access rights
- Your Environment
- Text Editors
- Input/output redirection
- Pipelines and filters
Intro to the ACCRE Cluster
This class gives an overview of the ACCRE cluster, including basic commands. It is required for all new users.
- Logging on to the cluster
- Transferring files to and from the cluster
- Setting your environment (Lmod)
- Scheduler basics
- Cluster etiquette
- Available storage
Intro to SLURM
This class gives an overview of SLURM, which is used to schedule computing jobs on the ACCRE cluster. It is required for all new users.
Please review the One Million Digits of Pi tutorial before attending this session.
- Components of the scheduler (SLURM) and their functions
- Submitting a job for execution
- Changing scheduler options after a job has been submitted
- Checking the status of a submitted job
- Checking your account’s status (fairshare)
- Using information about the overall cluster status (node availability) to optimize the timing of your job’s execution
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 Some of this information may be out of date (e.g. setpkgs was the package manager used by ACCRE many years ago, and has been replaced with Lmod).
- Building, Compiling, and Installing Software
- Setting up your compiling environment
- Searching for symbols
- Determining appropriate compilers
- Determining and adding library paths
- GPU Programming and Computing
