Három ténylegesen működő Grid infrastruktúrát (Magyar KlaszterGrid, LHC Gridet, NorduGrid) ismertetnek, és bemutatják a P-GRADE portált, amelyekkel ezeket a Grid infrastruktúrákat a nem informatikus alkalmazók, pl. kémikusok, biológusok is könnyen elérhetik.

Production Grid systems and their programming
Péter Kacsuk, Balázs Kónya, Péter Stefán
There is a large variety of Grid test-beds that can be used for experimental purposes by a small community. However, the number of production Grid systems that can be used as a service for a large community is very limited. The current tutorial provides introduction to three of these very few production Grid systems. They represent different models and policies of using Grid resources and hence understanding and comparing them is an extremely useful exercise to everyone interested in Grid technology.
The Hungarian ClusterGrid (www.clustergrid.iif.hu
) connects clusters during the nights and weekends. These clusters are used during the day for educational purposes at the Hungarian universities and politechnics. Therefore a unique feature of this Grid is the switching mechanism by which the day time and night time working modes are loaded to the computers. In order to manage the system as a production one the system is homogeneous, all the machines should install the same Grid software package.
The second even larger production Grid system is the LHC-Grid (lcg.web.cern.ch/LCG
) that was developed by CERN to support the Large Hydron Collider experiments. This Grid is also homogeneous but it works as a 24-hour service. All the computers in the Grid are completely devoted to offer Grid services. The LHC-Grid is mainly used by physicists but in the EGEE project other applications like biomedical applications will be ported and supported on this Grid.
The third production Grid is the NorduGrid (www.nordugrid.org
) which is a completely heterogeneous Grid connecting dedicated and non-dedicated resources ranging from small test clusters to TOP500 category national supercomputing resources. The Grid is dynamic, resources can join and leave at any time as they need. The NorduGrid runs on the ARC (Advanced Resource Connector) middleware, a Globus-based alternative grid solution developed by the NorduGrid collaboration. The main features of ARC are the stability, efficiency, portability and its user and system administrator friendliness. The flexibility of the middleware made possible the creation and the seamless production operation of one of the largest production Grid of the world. The dynamic Grid connects approx. 35 clusters from 10 countries providing more than 2000 CPUs for about 1000 authorized users.
Concerning the user view an important question is how to handle this large variety of production Grids and other Grid test-beds. How to develop applications for such different Grid systems and how to port applications among them? A possible answer for these important questions is the use of a Grid portal technology. The EU GridLab project developed the GridSphere portal framework that was the basis of developing the P-GRADE Grid portal. By the P-GRADE portal users can develop workflow-like applications including HPC components and can run such workflows on any of the Grid systems in a transparent way.
