Austrian Grid: Overview on the Project with Focus on Parallel Applications

Summary form only given. GRIDs are large-scale distributed computing infrastructures that enable the integrated and collaborative use of high-end computers, networks, databases, and scientific instruments owned and managed by multiple organizations. Currently, a lot of national and international grid projects aim in building and using grids. One of them is the Austrian Grid. This project targets different areas of applications, including medical sciences, high-energy physics, applied numerical simulations, astrophysical simulations and solar observations, as well as meteorology and geophysics. Corresponding to the previous experience of the initiators of the project a lot of the applications are parallel ones. In the first part of the talk an overview on Austrian Grid will be presented. We will speak about the goals and the results in general. In the second part of the lecture the focus will be on parallel applications. We will discuss some answers given by the research of Austrian grid to questions like: how to map parallel applications onto a grid, which kind of tools are necessary, which extensions of standard middleware are desirable
