Warewulf Enables Flexible, Scalable, and Simplified Operating System Management for Clusters

Highly Scalable Cluster Management and Provisioning

Whether you’re managing tens of nodes or tens of thousands, you want the simplest way to provision the operating system, a single point of control, and ease of configuration.

“Warewulf 4 is the HPC cluster manager I always wanted. Its OCI integration streamlines and simplifies the image creation process, making it trivial to build customized cluster environments on the foundation of the growing container ecosystem.”

Jonathon Anderson, CIQ Solutions Architect Manager

Do. Science.

Warewulf was created to enable your research, your science, and your systems at scale. 

Warewulf pioneered stateless operating system provisioning at its inception back in 2001. Now in its fourth generation, Warewulf adds integration with the container ecosystem that drives modern CI/CD and DevOps processes and remains a high-powered yet flexible cluster manager, whatever your needs.
Warewulf is the cluster management toolkit for OpenHPC, powering thousands of clusters worldwide.

“Simple”

Isn’t Just a Marketing Word.

Warewulf is a cluster management and provisioning platform for all types of clusters, and is designed to produce secure, scalable, turnkey cluster deployments that are both flexible and easy to maintain. From small, researcher-run clusters all the way to supercomputers with tens of thousands of nodes, Warewulf scales both up and down to be easy to deploy, administer, debug, and secure in any clustering environment.

“Stateless”

Scalable. Extensible. Easy.

The Warewulf project pioneered the concept of stateless provisioning in High Performance Computing (HPC), setting the standard for large-scale cluster deployment. After many years of development, Warewulf transformed from a basic provisioning system into the leading cluster management platform for all HPC environments.

Its stateless provisioning paradigm makes Warewulf highly scalable and easy to deploy, administer, debug, and secure in any clustering environment.
