[标题]:Numerical methods for the 3D shallow water equations on vector and parallel computers

[文摘]:Since three dimensional models require a great computational effort, it is important to construct methods that are not only accurate, but also efficient in vector and parallel computers. The accuracy and efficiency of a conditionally stable and an unconditionally stable method are compared on a minisupercomputer with four vector processors. The unconditionally stable method consist of two stages and required the solution of a sequence of linear systems. For the solution of these systems, a Jacobi type iteration method and a conjugate gradient iteration method are applied. The performance of both iteration methods is accelerated by a technique based on smoothing. Both explicit and implicit smoothing is examined. It turns out that the unconditionally stable method is more efficient than the conditionally stable method. (ESA)
