并行迭代线性求解器的非结构网格有限元应用,最初开发的地球模拟器(ES),移植到各种类型的并行计算机。平面MPI和混合并行编程模型的性能进行了比较ES,日立SR 8000,IBM SP-3和IBM P5型595超级计算机。着色和不同的存储方法的系数矩阵的效果进行了评估,在各种类型的应用。超过104个处理器的性能是使用最多103个处理器的测量数据来估计的。
Parallel iterative linear solvers for unstructured grids in FEM applications, originally developed for the Earth Simulator (ES), are ported to various types of parallel computer. The performance of flat MPI and hybrid parallel programming models is compared for the ES, Hitachi SR8000, IBM SP-3 and IBM p5-model 595 supercomputers. The effect of coloring and of different storage methods for coefficient matrices are evaluated in various types of application. Performance for more than 104 processors is estimated using measured data for up to 103 processors.
