Charliecloud with Nvidia GPUS via standards new and old

Workshop: 7th International Workshop on Containers and New Orchestration Paradigms for Isolated Environments in HPC (CANOPIE-HPC)

Authors: Megan Phinney and Angelica Loshak (Los Alamos National Laboratory (LANL))

Abstract: With the increase of GPU workflows, GPU containers are needed for these complex workflows. GPU containers get the flexibility of containers and the performance benefits of GPUs. For popular nVidia containers, there are extra requirements such as access to GPU drivers, and nvidia-container-toolkit installed.

There are three new features that Charliecloud is working on specifically to help GPU workflows. They are: nVidia CDI, ENTRYPOINT and CMD Dockerfile instructions, and a tool that would work similarly to docker-compose. While CDI was implemented to bring Charliecloud up to standard, ENTRYPOINT and docker-compose are features that users have been explicitly asking for.

This lightning talk will discuss how Charliecloud is currently working adding new tools and features to better support our GPU users and a status update of nVidia CDI, ENTRYPOINT, and docker-compose. LA-UR-25-28140
