EROS: The Extremely Reliable Operating System

EROS is a new operating system originally implemented at the University of Pennsylvania. The project has now migrated to Johns Hopkins University. EROS 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.
