The Austrian Grid Initiative – High Level Extensions to Grid Middleware

The Austrian Grid initiative is the national effort of Austria to establish a nation-wide grid environment for computational science and research. The goal of the Austrian Grid is to pursue a variety of scientific users in utilizing the Grid for their applications, e.g. medical sciencs, high-energy physics, applied numerical simulations, astrophyscial simulations and solar observations, as well as meteorology and geophysics. All these applications rely on a wide range of diverse computer science technologies, composed from standard grid middleware and sophisticated high-level extensions, which enable the implementation and operation of the Austrian Grid testbed and its applications.
