An open source cluster provisioning system for HPC and enterprise computing. Warewulf utilizes container-based node images and iPXE to easily serve a specified operating system configuration out to potentially thousands of nodes at once. Warewulf also allows for configuration overlays to be applied to a given node, so it’s possible, for example, to have a base compute node image that you have Warewulf serve for CPU nodes, and then an overlay with GPU settings that gets applied to that base image on your GPU nodes and automatically brings them up with the correct configuration. Warewulf has been used by a wide variety of sites for over 20 years and is continuously improving with a robust development community behind it.
