          "Parallel methods for IVPs in a transputer environment"

   The Centre for Mathematical Software Research at the University of
Liverpool, in conjunction with NAG, is developing a library of scientific
software designed to run in a transputer environment. In this talk I will
discuss the work being done for ordinary differential equations.

   I will begin with a brief introduction to transputers and the
configurations that are suitable for IVP packages. Then I will discuss the
difficulties that must be overcome to ensure the transputers are used
efficiently. Following this, I will discuss some properties of the large
class of parallel methods that can be placed in the general framework of
block multivalue methods. In particular, I will present a rigorous analysis
of the local error of these methods, and apply the theory to predictor-
corrector methods for non-stiff problems. Finally, I will discuss the
question of whether massive parallelism across a method is a realistic goal
for the block multivalue methods.
