Processor Design Issues for Parallel Machines

This paper addresses processor design issues for multiprocessor architectures. We assert that some architectural features desirable for a uniprocessor are not as eeective in a multiprocessor. Issues aaecting processor design include granularity, degree of parallelism, cache and network eeects, and dynamic load balancing. We show that using single-instruction-issue processor with dynamic instruction scheduling as multiprocessor building blocks can result in balanced systems that achieve high performance on several known benchmarks.dation doctoral fellowship.
