The Center for Supercomputing Research and Development (CSRD) is pushing the frontiers of computational technology while building the Cedar System, a prototype multiprocessor. Clusters of 8 tightly-coupled processors are being bought from Alliant Computer Systems, which based its system design on earlier University of Illinois work by the CSRD group. CSRD efforts span the hardware, software, and applications areas. The hardware group is designing and building a global network and shared global memory, as well as an Alliant interface. This will allow 4 clusters (of 8 processors) to operate together in 1988 and up to 8 clusters in the future. Synchronization and data sharing are allowed by powerful hardware primitives. The software group is developing a Unix-based multiprocessor operating system and a Parafrase (KAP)-based restructuring compiler. The compiler will transform serial as well as parallel Fortran constructs to exploit the system, dealing with vector as well as multiprocessing parallelism. The applications group is developing parallel algorithms and using them in a number of engineering and scientific applications. Thus, CSRD is working for a rapid architectural increase in speed across a number of applications. If Cedar can be exploited as planned on single jobs, speedup factors of one thousand per decade will be possible in future implementations.
