Abstract Grid computing is rapidly establishing itself as the fundamental tool for computational science in the next years. Regional grid infrastructures are developing in many areas of the world, among which the Indian subcontinent, The Workshop aims at offering an opportunity to learn how grid computing works to computational scientists from different areas, providing an overview of the Grid services and discussing and experimenting on the constraints that the grid paradigm imposes on applications, and the requirements that their applications present to the grid infrastructure.
