Dr.  Ivar Lie, of the University of Toronto, will speak
on   ``Runge-Kutta  Methods  for  Vector  and  Parallel
Computers''.

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.
