IntroductionThe rapid evolu~ion of high performance computing (HPC) platforms has vastly improved the computing environment available for numerical simulation.With the advances in hardware technology, the complexity of writing software that makes effective use of the available hardware has also increased dramatically.Our research is aimed at solving this problem for application domains modeled by partial differential equations, by developing easy to usc, high level software environments called problem solving environment that allow users to quickly make efficient use of available HPC platforms.This paper reports on I jELLPACK 1 , a problem solving environment for the numerical simulation of PDE models on high performance computing platforms.j jELLPACK allows the user to (symbolically) specify partial differential equation problems, specify the solution algorithms to be applied, solve the problem and finally analyze the results produced.The problem and solution algorithm are specified in a custom high level language through a complete graphical editing environment.A knowledge based environment assists users in selecting an optimal solution strategy for a given problem.Problems can be solved using any of the built-in solvers, or the user can introduce a new solver into the system and leverage from the infrastructure in the system.Problems may be solved on a parallel machine (or a network of workstations) using built-in domain decomposition based solvers.
