Abstract

We propose a fabled boundary condition forecast algorithm for multi grid parallel computing, and derive a forecast function formula in this paper. Numerical results of one and two-dimension boundary condition problems obtained with the algorithm in a PVM network computing environment show that the algorithm has high parallel efficiency.
