我们讨论了使用额叶方法解决稀疏线性方程的稀疏未对称系统的设计功能。我们特别考虑用户界面,内部数据结构,枢纽策略以及机器依赖性的隔离。我们说明了IBM 3033和Cray-1上各种测试问题的代码的性能。
We discuss design features of a code which solves sparse unsymmetric systems of linear equations using a frontal method. We consider in particular the user interface, the internal data structures, the pivoting strategy, and the isolation of machine dependencies. We illustrate the performance of our code on a variety of test problems on both the IBM 3033 and the CRAY-1.
