### Parallel Simulation of Multicomponent Systems

**Mike Heath, University of Illinois**

Complex engineering systems and other physical phenomena often involve
multiple components whose interactions are crucial to determining the overall
behavior of the system. Simulation of such multicomponent systems offers
numerous challenges in mathematical modeling, geometric representation,
algorithm design, and software engineering. Moreover, the enormous computational
demands of such simulations usually require implementation on large-scale
parallel computers, which introduces further issues such as partitioning,
load balancing, scalability, etc. In this talk we will address many of these
issues, as exemplified by whole-system simulation of solid propellant rocket
motors on massively parallel computers.
