A CORBA-Based Environment for Coupling Large-Scale Simulation and Optimization Software.

Abstract

Simulation is an essential part in computational science and engineering. Since the underlying physical models become more and more complex, the adjustment of certain model parameters (``parameter identification'') is often a nontrivial task and should be addressed by means of efficient numerical optimization algorithms. We describe an environment for coupling simulation and optimization software. The modular architecture of the system supports easy modification of the problem configuration, including the exchange of software components. Therefore our tool is well-suited for rapid prototyping of optimization problems.
