Performance evaluation of the IBM RISC System/6000: comparison of an optimized scalar processor with two vector processors
Margaret L. Simmons, Harvey J. Wasserman · Conference on High Performance Computing (Supercomputing) · 1990
RISC System/6000 computers are workstations with a reduced instruction set processor recently developed by IBM. This report details the performance of the 6000-series computers as measured using a set of portable, standard-Fortran, computationally-intensive benchmark codes that represent the scientific workload at the Los Alamos National Laboratory. On all but three of our benchmark codes, the 40-ns RISC System was able to perform as well as a single Convex C-240 processor, a vector processor that also has a 40-ns clock cycle, and on these same codes, it performed as well as the FPS-500, a vector processor with a 30-ns clock cycle.
