ACES: Containers for Scientific Workflows (Singularity / Apptainer)

Overview

Instructor: Richard Lawrence

Time: Tuesday, October 22, 2024 — 10:00AM-12:30PM CT

Location: Online using Zoom

Prerequisites: Current ACCESS ID, basic Linux/Unix skills. Python skills recommended.

This short course provides an overview of container features for the purpose of helping the user determine whether containers are a useful tool for their workflow. This course covers Singularity syntax, the use of container repositories, practices for working with container images, and some example use cases for containers in the HPC setting. Exercises will be performed through the command line, but other workflows such as batch and GUI will be showcased.

Registration will open up on this webpage by the end of the month before this class.
