The ASCI Blue-Pacific machines are large parallel systems comprised of thousands of processors. We are currently developing and testing a gang-scheduling job control system for these machines that exploits space and time-sharing in the presence of dedicated communication devices. Our initial experience with this system indicates that, though applications pay a small overhead overall system performance as measured by queue time improved significantly. This gang-scheduling system is planned for deployment into production mode during 1999 at Lawrence Livermore National Laboratory.
