Numerical optimisation as grid services for engineering design

Abstract

In this paper we discuss the use of Grid services, an emerging Internet-based technology, to enable the application of numerical optimisation algorithms in heterogeneous, distributed systems for engineering design optimisation tasks. By being presented as Grid services, numerical optimisation algorithms can be consumed with a number of message interactions. The services are built using a combination of standard Web services and newly developed Grid technologies, based on the concept of Reverse Communication. The proposed approach eases the burden of integration by encapsulating optimisation algorithms into generic interfaces, which can be integrated into different client environments. The design of the optimisation Grid services is explained in detail, and is illustrated with concrete implementations. We also demonstrate the use of the optimisation services with real engineering design optimisation problems performed in scripting problem solving environment
