  abstract= "As part of the Alvey ParSiFal project, Logica Cambridge has
     been developing a model of a significant gas distribution
     network, in order to explore the potential for improvements
     in modelling speed using large numbers of transputers.There
     are two basic approaches to continuous simulation - the
     explicit and the implicit. The implicit approach models an
     entire system as a set of equations. Current implementations
     are well suited to conventional mono-processor machines but
     it is difficult to parallelize the algorithm and
     consequently to fully exploit the potential of
     transputers.The explicit approach models components such as
     pipes as individual objects which can be directly mapped
     into parallel processes, making it ideally suited to the
     transputer/occam architecture. However, explicit simulation
     is inherently expensive in terms of computational resources.
     To enhance performance we are also working on improvements
     to the model.We have developed a system using an explicit
     algorithm and have simulated networks ranging from 20 to
     500+ objects. Preliminary results indicate that the explicit
     algorithm can efficiently exploit high degrees of
     parallelism."
