This course introduces the use of Containers using the Charliecloud software suite. Exercises will be performed using the ACES cluster, a composable accelerator testbed at Texas A&M University. This workshop will provide participants with background and a hands-on experience to use basic Charliecloud containers for HPC applications. We will discuss what containers are, why they matter for HPC, and how they work. We'll give an overview of Charliecloud, the unprivileged container solution from Los Alamos National Laboratory's HPC Division. Participants will build toy containers and containerize real HPC applications, and then run them in parallel on a cluster. This will be a highly interactive workshop with lots of Q&A.
The presentation slides are available as downloadable PDF files.
This session will address the following topics:
- "What are containers?" "Why Charliecloud?"
- Pulling images
- Running images
- Building images
- SquashFS workflow
