It provides the functionality grid users require, and offers grid developers the opportunity to test and alter grid components while the grid is in use. The grid was proven to operate properly by testing several applications and introducing new compo- nents. Its performance is tested by the ”sleep testing technique”, and a by implementing a quantum physics calculation. The user friendliness is also evaluated with the latter distributed computational problem. The possibility to port the system onto well established systems like CON- DOR and GLOBUS is discussed.
