Distributed virtual test bed: An approach to integration of CAE systems in UNICORE grid environnement

Computer-Aided Engineering (CAE) systems demand a vast amount of computing resources to simulate modern hi-tech products. In this paper, we consider the problem-oriented approach to access remote distributed supercomputer resources using the concept of distributed virtual test bed (DiVTB). DiVTB provides a problem-oriented user interface to distributed computing resources within the grid, online launch of CAE simulation, automated search, monitoring and allocation of computing resources for carrying out the virtual experiments. To support the concept of DiVTB the DiVTB technology was developed. DiVTB technology provides a solution for the development and deployment of DiVTB, integration of most common CAE systems into the distributed computing environment as grid services (based on the UNICORE grid middleware) and web access to CAE simulation process.
