Integration of the ISS into the VIOLA meta-scheduling

The authors present the integration of the Intelligent (Grid) Scheduling System into the VIOLA meta-scheduling environment which itself is based on the UNICORE Grid software. The goal of the new, integrated environment is to enable the submission of jobs to the Grid system best-suited for the application workflow. For this purpose a cost function is used that exploits information about the type of application, the characteristics of the system architectures, as well as the availabilities of the resources. This document presents an active collaboration between Ecole Polytechnique Fédérale de Lausanne (EPFL), Ecole d\\\'Ingénieurs et d\\\'Architectes (EIF) de Fribourg, Forschungszentrum Jülich, Fraunhofer Institute SCAI, and Swiss National Supercomputing Centre (CSCS).
