EROS: The Extremely Reliable Operating System

EROS is a new operating system being implemented at the University of Pennsylvania. The system merges some very old ideas in operating systems with some newer ideas about performance and resource management. The result is a small, secure, real-time operating system that provides orthogonal persistence.

Effective April 14, 1999, the EROS website has moved to http://www.eros-os.org/. Please update your links.
