DEPARTMENT OF COMPUTER SCIENCE UNIVERSITY OF WATERLOO SEMINAR ACTIVITIES SCIENTIFIC COMPUTATION SEMINAR - Thursday, October 15, 1987 Dr. Ivar Lie, of the University of Toronto, will speak on ``Runge-Kutta Methods for Vector and Parallel Computers''. TIME: 4:00 PM ROOM: MC 5097 ABSTRACT Several good codes implementing Runge-Kutta methods are currently used for solving both non-stiff and stiff ordinary differential equations. When we are using vector and parallel computers to solve our ODE's, we want the solvers to be as efficient as possible on these types of architectures. The talk will discuss how well-known Runge-Kutta codes can be vectorized to run efficiently on such computers as the Cray X-MP, and how we can design Runge-Kutta methods for parallelism across the method. Results from numerical experiments showing speedup factors for vectorized code vs. non-vectorized code and parallel methods vs. serial methods will be reported.
