The goal of SZTAKI Desktop Grid is to provide a solution to exploit the spare capacities of home PCs, or computers located at different sites of a company or an institute. A desktop grid can interconnect a large number of distributed resources to solve complex applications. With the help of its cost effective and green solution, SZTAKI Desktop Grid supports various international and national
research projects from the fields of drug discovery, environmental modelling, data signal processing and so on. Based on the gained experiences, the laboratory addressed the interoperation between desktop and service grids, and elaborated the 3G Bridge; a generic Grid-to-Grid bridge solution.
