Parallel computer is an important area of the research of high - performance computer , and the efficient , rapid , large - capacity interconnection network is the base of large - scale parallel computer 并行计算机是高性能计算机领域的重要研究方向,大规模并行机的关键是需要高效、快速、大容量的互连网络,所以改善并行计算机性能的关键问题是设计高性能的互连网络。
The performance model has been validated against the implementation results obtained on a dawing tci700 parallel computer and can be readily used to estimate the performance before the optimistic simulation is implemented 在曙光tc1700并行机上的性能实验表明,我们的解析性性能分析模型得到的结果与实际实现的结果是非常接近的,可以用于乐观仿真实现前的性能预测。
It is found that when the number of the grids is over 512000 , the efficiency of two parallel computers is more than 67 . 9 % , and over 52 . 8 % by four computers . and the efficiency will improve as the grid number increases 通过测试发现当网格数量超过512000时,两台计算机并行效率超过67 . 9 ;四台计算机并行效率超过52 . 8 ,并且随着网格数量增加,并行效率能够得到进一步提高。
