Abstract

The Common File System (CFS) is a file management and mass storage system for the Los Alamos National Laboratory's computer network. The network has a core of worker machines that currently includes four Cray-1S supercomputers, four CDC 7600s, and one CDC 6000 with a combined capability of over 200 million floating point operations per second. Smaller machines, such as the DEC VAX 11-780 and the CDC Cyber 73s, are used as special-purpose worker computers. Each worker machine runs one of the five different operating systems used in the network. They are front-ended by a communication network of over 2500 terminals that service 3500 users and are back-ended by a file transport network that includes the CFS file storage system, the Print and Graphics Express Station (PAGES) output system, and the Extended Network Access System (XNET) that connects many distributed processors to the network.
