Paper Abstract

Computing a gravity model on a sequential machine requires 0(N2) time, where N is the degree and order of the model. With the increasing demand for higher resolution gravity models, it will be necessary to develop more efficient techniques for performing the computations required by these models. In this paper, we describe a parallel mapping of a gravity model on a linear array. The mapping uses N +5 cells running in parallel to compute the gravity equations in 0(N) time. The mapping is the basis for an implementation on the Warp computer at Carnegie Mellon.
