Classification and evaluation of parallel computer systems

  • Roger W. Hockney
Part I - Introduction To The Seminar
Part of the Lecture Notes in Computer Science book series (LNCS, volume 295)


A classification is presented of both vector (i.e. SIMD) and parallel (i.e. MIMD) computers, and two simple benchmarks are defined to assess performance. Results are presented for the Cray X-MP vector computer, and the LCAP parallel system of ten FPS-164 computers.
