本文描述了适合三种类型预处理的共轭梯度算法的并行化，以便在分布式内存并行计算机上计算大型有限元复杂稀疏方程组。使用60000自由度的问题来分析和比较并行性能。最后给出了完美导电飞机对平面波的电磁散射的一个大例子。
This paper describes the parallelization of the conjugate gradient algorithm fitted with three types of preconditioning in order to compute large finite element complex sparse system of equations on a distributed memory parallel computer. Parallel performances are analyzed and compared using a problem of 60000 degrees of freedom. The electromagnetic scattering of a plane wave by a perfect electric conducting airplane is finally given as a large example.
