Summary:Abstract: "The aim of this paper is to design a class of two-step Runge-Kutta-Nyström methods of arbitrarily high order for the special second-order equation y''(t)=f(y(t)) for use on parallel computers. Starting with an s-stage implicit two-step Runge-Kutta-Nyström method of order p with k=p/2 implicit stages, we apply the highly parallel predictor-corrector iteration process in P(EC)[superscript m]E mode. In this way, we obtain an explicit two-step Runge-Kutta-Nyström method that has order p for all m and that requires k(m+1) righthand side evaluations per step of which each k evaluations can be computed in parallel. By a number of numerical experiments we show the superiority of the parallel predictor-corrector methods proposed in this paper over both sequential and parallel methods available in the literature."
