Experiences with MPI Application Development within int.eu.grid: Interactive European Grid Project

Nowadays, a growing number of researchers and application developers profit by Grid infrastructures to run complex compute- and datamassive applications in a distributed way to get results in a reasonable time period. Applications come from many different scientific areas, such as medicine, physics or environment, etc. The European Gridproject int.eu.grid addresses the challenge of offering a production-level e-Infrastructure to interactive (MPI) applications. Within this project, the MPI libraries Open MPI and/or PACX-MPI are employed. Application support is also available through the MPI verification tool MARMOT, which will be described in this paper
