P-GRADE Grid portal offers workflow construction and execution mechanisms for grids including execution and performance visualization, advanced security features, access to information systems and resource brokers, and multi-grid support. Currently, P-GRADE Grid portal is the official portal of HUNGRID (Hungary), SEE-GRID (South- Eastern European countries), and VOCE (Virtual Organization of Central European countries) grid infrastructures, and also available world-wide for 15 user communities; among other infrastructures, for UK National Grid Service, White Rose Grid (UK), KnowledgeGrid (Malaysia), TR-GRID (Turkey), Swiss Grid (Switzerland), Baltic Grid (EENet), ClGrid (Chile). P-GRADE portal is integrated with the GEMLCA grid legacy code architecture making the usage of legacy applications possible in grids. The new generation of the Grid portal, the gUSE environment has been developed in the frame of CancerGrid and other projects based on Webservices and enhanced workflow execution mechanisms.

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.
