Beowulf
From NASA High Performance Computing and Communications Project, based on commodity hardware
Implemented as an add-on to Linux, and each node runs a copy of Linux, with kernel extensions for global namespaces
Examples of Beowulf system software:
- Beowulf Distributed Process Space – Allow process ID space to span machines, provide single system image, start processes on other nodes
- Beowulf Ethernet Channel Bonding – Combine multiple low-cost links into a single logical network
- Pvmsync – Provide synchronization and shared data objects in a cluster
- EnFuzion – Set of tools for parametric computing
