Abstract

Cache design is explored for large high-performance multiprocessors with hundreds or thousands of processors and memory modules interconnected by a pipelined multistage network. Multiprocessor conditions are identified and modeled, including: (1) the cost of a cache coherence enforcement scheme; (2) the effect of a high degree of overlap between cache miss services; (3) the cost of a pin-limited data path between shared memory and caches; (4) the effect of a high degree of data prefetching; (5) the program behavior of a scientific workload, as represented by 23 numerical subroutines; and (6) the parallel execution of programs. This model is used to show that the cache miss ratio is not a suitable performance measure in the multiprocessors of interest and to show that the optimal cache block size in such multiprocessors is much smaller than in many uniprocessors.
