This paper describes the architecture of a new large multi-processor computer system being built at Carnegie-Mellon University. The system allows close cooperation between large numbers of inexpensive processors. All processors share access to a single virtual memory address space. There are no arbitrary limits on the number of processors, amount of memory or communication bandwidth in the system. Considerable support is provided for low level operating system primitives and inter-process communication.
