Warewulf

Modern, Scalable, HPC Cluster Management & Provisioning

Warewulf simplifies management and scale of HPC clusters.

Warewulf: The Open Source Choice for HPC Cluster Management

Warewulf streamlines the deployment and management of large Linux clusters. It presents a modern approach to managing complex clustered infrastructure and pioneered the concept of stateless computing

Stateless Provisioning

Warewulf has pioneered the practice of stateless computing in HPC. Compute nodes typically boot from the network and run entirely in memory using an image provided by the Warewulf server. This approach to imaging makes management, updates, and reimaging efficient and fast.

While primarily stateless, Warewulf can also handle stateful nodes with local disks, whether you want local storage for virtual memory, local scratch, log retention, or clustered file systems.

Centralized Management

A central Warewulf server manages the operating system images, configurations, and provisioning of all the compute nodes in the cluster. This provides a single point of control for administration, and a single source of truth for configuration.

Hardware and OS Agnostic

Warewulf can run cluster nodes independent of the architecture and configuration of the server node, supporting both x86 and ARM CPUs among others. It can provision most Linux distributions, including Rocky Linux, Red Hat Enterprise Linux (RHEL), CentOS, SUSE, Debian, and Ubuntu.

Container Integration

Warewulf (optionally) leverages container images and tooling (whether you use Docker, Podman, or Apptainer) to define and manage node images. This greatly simplifies image creation and management, and supports integration with modern DevOps practices.

CLI and API

Warewulf is typically managed via a powerful command-line interface; but it also delivers a REST API that opens up the platform for automation and tighter integration into local infrastructure.

Developed in the Open

With over 500 GitHub stars, the Warewulf GitHub project is a testament to the value of open source development in action. It includes contributions from CIQ, Intel, OpenHPC, and SUSE, along with academic and research partners.

Tech Preview

Warewulf Web Interface

CIQ recently opened up a tech preview program of a new Web Interface for Warewulf. Built on Cockpit, the new UI simplifies cluster administration for new and existing administrators while maintaining Warewulf’s flexibility for research, commercial and fully-integrated environments.

Warewulf In Use

While primarily used in High-Performance Computing (HPC) clusters, Warewulf's flexible architecture makes it suitable for other clustered Linux environments, including:

HPC Clusters
Clustered Web Servers
Kubernetes
Large-scale test & development environment
Visualization and Render Farms
Distributed Storage Clusters
Parallel File Systems
