Abstract:

The CRAY X-MP 2- and 4-processor memory systems are analyzed and simulated using an instruction-level timing simulation of up to 16 processors. This study indicates a disturbing counter-intuitive trend to longer delays in vector accesses as both the number of processors and memory banks increase proportionately. This delay appears to be related to access start-up delays, which are determined for various memory organizations. Keywords include Supercomputers Simulation and Parallel processors.
