摘要：
It becomes more and more interesting to construct multithreaded parallel machines using stock processors due to their high performance/price ratio. However no quantitative analysis has been reported on the effectiveness of various node configurations and its impact on the overall performance. In this paper we explore three different node configurations in detail and compare their dynamic characteristics through the instruction-level simulation with six benchmark programs. Our experiments show that employing a dedicated processor for communication and synchronization is a reasonable approach because it can almost double the performance. Several factors that limit the overall speedup are also presented.
