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.
