DRM4G: Aggregation of distributed resources for scientific communities

Nowadays, there are available a huge variety of computing resources such as PCs, workstations, clusters or grid services, among others. But the usage of these resources in a distributed form impose new challenges on scientific communities. Recently, we have started an effort for developing a tool called DRM4G, based on GridWay, which enables the submission and control of jobs from distributed resources managers –FORK, PBS, SGE, LSF, LoadLeveler and SLURM– to grid services –Globus and gLite–. The demo is going to show how DRM4G gives concurrently access to distributed resources such as several EGI VOs and the RES infrastructure. And, it will demonstrate the scalability of the system handling large-scale tasks.
