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.
