Memory-conflict simulation of a many-processor CRAY architecture. Part 1. A CRAY X-MP study. Interim report

The performance of three Fortran kernels and two assembly kernels (including two linear algebra kernels) is simulated for a CRAY X-MP multiprocessor architecture of up to 16 processors and 256 memory banks. The effects of variations on the X-MP-2 memory conflict resolution protocol, including X-MP-4 protocol, are studied.
