Notes:
This paper discusses aspects of vectorizing a recently developed calculation procedure for multidimensional recirculating fluid flows. The solution algorithm uses a coupled Gauss-Seidel relaxation operator in conjunction with the multigrid technique. The vectorization is performed on a CRAY X-MP/48 using a single processor. In this paper, the vectorization techniques used and the observed speed-ups are presented for a model problem of laminar flow in a two-dimensional square cavity. Large scale calculations with up to one quarter of a million finite difference cells (512 x 512) have been made in 45s of CPU time.
