OpenCHAMI

HPC System Management for Cloud Engineers and HPC Sysadmins

Open Composable Heterogeneous Adaptable Management Infrastructure

OpenCHAMI (Open Composable Heterogeneous Adaptable Management Infrastructure) is an open-source system management platform designed to bring cloud-like flexibility and security to High Performance Computing (HPC) environments. It provides modern tools to efficiently deploy, manage, and scale HPC clusters, making it easier for organizations to support both traditional scientific workloads and emerging AI, ML, and data-driven applications.

Key Features

  • πŸ›‘ Security-First Architecture – Implements zero-trust authentication, fine-grained access control, and OIDC-based authorization to safeguard HPC environments.
  • 🧩 Composable & Scalable – Modular, cloud-native design supports heterogeneous compute infrastructures across on-prem and cloud environments.
  • πŸ”§ Microservices-Based – Built on lightweight, containerized services, making deployment and scaling more efficient.
  • 🌐 Community-Driven & Open – Developed in collaboration with leading HPC sites under the Linux Foundation HPC initiative, ensuring transparency and innovation.
  • πŸš€ Fast Boot - Faster and more secure boot times with cloud-init. POST + 40 seconds!

Why OpenCHAMI?

HPC system management has traditionally relied on monolithic, complex, and rigid solutions that are difficult to adapt to modern workloads. OpenCHAMI bridges the gap between HPC and cloud-native technologies by providing:

  • Security & Compliance – Designed with modern security best practices for protecting critical infrastructure.
  • Cloud-Like Flexibility – Enables dynamic, on-demand scaling and automation of system resources.
  • Open & Transparent Governance – Unlike proprietary solutions, OpenCHAMI is community-led and continuously evolving.

Security

HPC jobs run in the context of a POSIX filesystem. Cloud APIs depend on access tokens that are limited in both scope and time. OpenCHAMI ships everything you need to bridge the two worlds.

Simplicity

OpenCHAMI can support the largest HPC systems with the most complex requirements, but the default install is useful within five minutes. Complexity is always "opt-in".

Modularity

Each of the components that comprise the OpenCHAMI system is designed to work in a standalone mode and can be fully replaced.
