Abstract

Grid is an evolving and maturing architecture based on several well-established services, including amongst others, distributed computing, role and group management, distributed data management and Public Key Encryption systems Currently the largest scientific grid infrastructure is Enabling Grids e-Science (EGEE), comprised of approximately ∼250 sites, ∼50,000 CPUs and tens of petabytes of storage. Moreover, EGEE covers a large variety of scientific disciplines including Astrophysics. The scope of this work is to provide the keen astrophysicist with an introductory overview of the motivations for using Grid, and of the core production EGEE services and its supporting software and/or middleware (known by the name gLite). We present an overview of the available set of commands, tools and portals as used within these Grid communities. In addition, we present the current scheme for supporting MPI programs on these Grids.
