Program granularity and performance in multiprocessor systems

Walter H. Burkhardt

Abstract

Performance in multiprocessor systems depends on various factors. Granularity of the program exerts a surprising effect on the performance. This relationship is investigated theoretically and experimentally for a transputer system of up to 24 slave modules. The results show a strong dependency of performance on particular values of processor number, granularity, and number of tasks to be computed.>
