摘　　要：An optimal multilevel preconditioner for plate problem was constructed in [7]. In this paper, the matrix presentation of the preconditioner is given and EBE technology is used to realize the saving and computing of global stiff matrix, interpolation matrix and transport matrix. An MPI algorithm is also given on Dawn 1000+.An optimal multilevel preconditioner for plate problem was constructed in [7].
