近几年来,国际上计算机与半导体工业发展飞速,在不断提高单机或单处理器性能的同时,多处理机系统和并行计算机已大量进入市场。这是因为并行机具有比单机更高的速度,更高的作业吞吐量,更高的性能价格比,更高的可扩充性和可靠性。所以,并行机已成为90年代计算机发展的主流。 In recent years, the international computer and semiconductor industry has developed rapidly, while continuously improving the performance of single or single processor, multiprocessor systems and parallel computers have entered the market in large quantities. This is because parallel machines have higher speeds than single machines, higher job throughput, higher cost performance, higher scalability and reliability. Therefore, the parallel machine has become the mainstream of computer development in the 90s.
