“…Building on resources available on IGI, the INFN theoretical physics community (Theophys VO) has recently started a project [65] aiming at fulfilling the requirements of medium-sized HPC applications. This project is achieving important results for the Theophys community, such as the deployment of a common infrastructure for parallel applications that shares the same platform with the other Grid resources available for serial jobs.…”

Distributed Computing Infrastructures have dedicated mechanisms to provide user communities with computational environments. While in the last decade the Grid has demonstrated to be a powerful paradigm in supporting scientific research, the complexity of the user experience still limits its adoption by unskilled user communities. Command line interfaces, X.509 certificates, template customization for job submission and data access tools require end-users to dedicate significant learning effort and thus represent a barrier to access Grid computing facilities. In this paper, we present a Web portal that solves the aforementioned limitations by providing simplified Valerio Venturi deceased 25

Even though the Italian Grid Infrastructure (IGI) is a general purpose distributed platform, in the past it has been used mainly for serial computations. Parallel applications have been typically executed on supercomputer facilities or, in case of "not high-end" HPC applications, on local commodity parallel clusters. Nowadays, with the availability of multiple cores processors, Grid computing is becoming very attractive also for parallel applications but some problems exist in supporting of HPC applications on Grid environment. Here we describe the work made to set up a HPC testbed for "not high-end" HPC applications, based on IGI Grid technologies, to find solutions to those problems. Participating sites have been selected among the ones running HPC clusters in Grid environment. Each of them contributed with their specific HPC experience and their available resources to the present test, which encompasses an unprecedented large set of applications from different disciplines in the fields of astronomy, astrophysics, chemistry, climatology, material science and oceanography. In addition to computing resources sharing, the main contribution of each participant was the identification of the real requirements of his application also related to the current middleware limitations and then the realization of a test platform enhanced with additional HPC solutions and configurations developed in a tight collaboration between HPC administrators, users and IGI managers. The main work was on computational resources selection, data management and the definition, the deployment and the documentation of the software execution environment. The outcoming results of the testbed represent the basis of the HPC support in the IGI production infrastructure.
