The Sprite Operating System
Sprite is a research operating system developed at the University of California, Berkeley, by John Ousterhout’s research group.
Sprite is a distributed operating system that provides a single system image to a cluster of workstations. It provides very high file system performance through client and server caching. It has process migration to take advantage of idle machines. It was used as a testbed for research in log-structured file systems, striped file systems, crash recovery, and RAID file systems, among other things.
