Bootstrapping and Cluster DevOps with OpenCHAMI

Practical component: https://github.com/OpenCHAMI/tutorial-2025 This tutorial introduces the fundamentals of cloud-like system provisioning with OpenCHAMI and enable attendees to build on what they’ve learned by applying DevOps principles to manage OpenCHAMI clusters. OpenCHAMI is a relatively new open source, open governance project from partners: HPE, the University of Bristol, CSCS, NERSC, and LANL. It securely provisions and manages on-premise HPC nodes at any scale. With a cloud-like composable microservice architecture, and an emphasis on infrastructure as code, the tools to install and manage OpenCHAMI may not be familiar to many traditional HPC administrators. Having helped our own teams at LANL to make this transition, the presenters want to bring the same training to a broader audience. In this half-day tutorial, attendees will learn how each of the components in an OpenCHAMI system can be used to bootstrap their own virtual clusters in the first hour and then build on what they’ve learned to leverage DevOps workflows to automate the management of multiple clusters.
