The conjugation of High Performance Computing (HPC) and Grid paradigm with applications based on commercial software is one among the major challenges of today e-Infrastructures. Several research communities from either industry or academia need to run high parallel applications based on licensed software over hundreds of CPU cores; a satisfactory fulfillment of such requests is one of the keys for the penetration of this computing paradigm into the industry world and sustainability of Grid infrastructures. This problem has been tackled in the context of the PI2S2 project that created a regional e-Infrastructure in Sicily, the first in Italy over a regional area. Present paper will describe the features added in order to integrate an HPC facility into the PI2S2 Grid infrastructure, the adoption of the InifiniBand low-latency net connection, the gLite middleware extended to support MPI/MPI2 jobs, the newly developed license server and the specific scheduling policy adopted. Moreover, it will show the results of some relevant use cases belonging to Computer Fluid-Dynamics (Fluent, OpenFOAM), Chemistry (GAMESS), Astro-Physics (Flash) and Bio-Informatics (ClustalW)).

The Pi2s2 Project And The Sicilian Grid Infrastructure

The PI2S2 project (Barbera, 2007) aims at providing Sicily with a Virtual Laboratory running a computational Grid for scientific and industrial applications. The COMETA Consortium (Falzone, 2007), is a partnership among the Sicilian Universities of Catania, Messina and Palermo, the National Research Institutes for Nuclear Physics (INFN), Astro-Physics (INAF), Geo-Physics and Volcanogy (INGV) and the SCIRE Consortium. The COMETA Consortium (Barbera, 2006) developed the PI2S2 project and currently manages the infrastructure. The adopted standards rank it at a very high technology level to become an open, general purpose, on-demand facility for distributed computation and massive data storage (the first one on a regional scale in Italy). The Sicilian infrastructure is connected to the international computational Grids (See Figure 1) in order to improve both the level of scientific collaboration between the Sicilian Universities and Research Institutes and their counterparts in the rest of the world, and enhance the competitiveness of local Small and Medium Enterprises.
