Distributed Parametric Optimum Design Using GridRPC

Abstract

In this paper, a new parametric optimum design system that is suited for the global computing environment is proposed and the system is discussed using with the parallel finite element analysis. In general, many studies of the parallel distributed calculation are discussed about a collection of computing resources in local area network. On the other hand, the researches of the highly efficient wide area calculation system called "Grid Computing" are done briskly now. At the Grid System, the computing resources connected to the wide area network are recognized as one system by using middleware. Ninf system is a kind of the middleware called Grid RPC. Evaluation procedures in optimization are executed frequently, and each procedure is executable asynchronously. In this study, evaluation procedures are called asynchronously using "Ninf remote procedure call". Each evaluation is calculated by ADVENTURE which is parallel finite element analysis system implemented by MPI.
