Int.eu.grid

The int.eu.grid project aims to provide a production quality grid computing infrastructure for e-Science supporting parallel and interactive applications. The infrastructure capacity is presently about 750 cores distributed over 12 sites in 7 countries, and it implies a much larger management and coordination effort to guarantee high availability and fast start-up mechanisms of (batch and parallel) interactive applications. Int.eu.grid is also strongly focused on providing a user-friendly access to the grid through a powerful GUI allowing a transparent access to grid resources and the possibility to interact in real time with running applications. In this chapter we present the management policies, infrastructure services, and operation mechanisms that enable interactivity over the grid bringing a new added value to grid environments.
