为地球模拟器（ES）开发的有限元非结构网格并行迭代线性求解器已移植到各种类型的并行计算机上。flat-MPI和混合并行编程模型的性能进行了比较ES，日立SR 8000，IBM SP3和IBM p5-型号595。在各种类型的应用中，着色和存储系数矩阵的方法的效果也进行了评估。使用最多10个处理器的测量数据估计了超过10个处理器的性能。
Parallel iterative linear solvers for unstructured grids in FEM applications, which were developed for the Earth Simulator (ES), have been ported to various types of parallel computers. Performance of flat-MPI and hybrid parallel programming model has been compared for ES, Hitachi SR8000, IBM SP3 and IBM p5-model 595. Effect of coloring and method for storage of coefficient matrices have been also evaluated in various types of applications. Performance with more than 10 processors has been estimated using measured data up to 10 processors.
