一个家庭的预处理器的迭代求解器的可分离的椭圆边值问题的球面几何数值天气预报中出现的已实施和测试的向量处理器。PCG-MILU（0）求解器在少量迭代中获得实际收敛，并在高分辨率下优于高度优化的直接求解器。
A family of preconditioners for an iterative solver of a separable elliptic boundary value problem in spherical geometry arising in numerical weather prediction has been implemented and tested on a vector processor. The PCG-MILU(0) solver obtains practical convergence in a small number of iterations and outperforms a highly optimized direct solver at high-resolution.
