ACES: Fundamentals of Containers
Overview
Instructor(s): Richard Lawrence
Time: Tuesday, March 3, 2026 1:30PM-4:00PM CT
Location: Online using Zoom
Prerequisite(s): Current ACCESS ID, basic Linux/Unix skills
This course introduces core concepts of containerization and covers basic and advanced containerization tasks with a focus on understanding best practices for containers on HPC systems. The course is intended to cultivate an in-depth general-purpose understanding of containers for an audience who may be unfamiliar with containers or may have previously used containers only in a specific context. Topics include building containers images, working with container repositories, and container features necessary for using containers on HPC systems. Exercises will be performed on the ACES cluster, a composable accelerator testbed at Texas A&M University, using the Charliecloud and Singularity container engines.
Course Materials
Participation
During the training, attendees are expected to use their own computer and complete the instructor-led examples and exercises.
