摘　　要：为实现高性能有必要采用细粒度的并行，但必须解决其中增大的通信开销问题。多线程计算不仅用来实现细粒度的并行，合理的调度策略还有助于隐藏通信延迟。但其中存在着线程切换开销的问题。In this paper, fine grain parallelism is emphasized in the design of massively parallel computers to acquire higher performance, but the increasing communication overhead should be solved first. Multithreads can not only implement fine grain parallelism effectively, but also be helpful to hide communication latency with reasonable scheduling strategies. So multithreaded computing is also proposed as a method for fine grained parallel processing. Multithreaded processors are expected to reduce the threads’ switching overhead.
