Warewulf was founded in 2001 and has been the dominant open source HPC cluster management solution because it solves the problems of cluster management and scale in a simple to implement manner.

Since its inception, it has been a cornerstone of HPC cluster systems worldwide, and CIQ is the official support and services provider for the community.

We’ve been further developing Warewulf to better support the container ecosystem and building turn-key cluster solutions for you.

Flexible support plans for your needs.

We support people, not sockets or cores. People.

Why? Because we believe in empowering people to do amazing things. When people succeed, teams succeed, when teams succeed, organizations succeed. We start where it matters most: with the people.

With this model, we don’t count systems, entitlements, cloud instances, virtual machines, or containers because they don’t count. It’s the people who count.
