摘要
针对Apram模型[1],研究了双曲型方程初边值问题差分格式的并行实现方法。文中不仅讨论了差分格式在Apram模型上的各种并行处理技术,而且对并行算法的可扩放性进行了讨论,最后设计了适合于Apram模型结构特征的并行计算程序,对二维Euler方程正规激波反射问题的计算实践。
The parallel implement of numerical schemes for initial boundary value problems of hyperbolic equations is discussed based on the Apram model. Not only some parallel techniques of difference schemes based on the Apram model but also the scalability of parallel algorithms are analysed. And, A parallel scheme is worked out to make full use of the structural characteristic of Apram model and bring it into full play. The numerical results show that the new model has the advantage of good scalability.
