Parallel Computing is at the verge of a new era. Multi-core processors make parallel computing a fundamental skill required by all computer scientists. At the same time, high-end systems have surpassed the Peta?op barrier, and s- ni?cant e?orts are devoted to the development of hardware and software te- nologies for the next-generation Exascale systems. To reach this next stage, processor architectures, high-speed interconnects and programming models will go through dramatic changes. The Message Passing Interface (MPI) has been the most widespread programming model for parallel systems of today. A key questions of upcoming Exascale systems is whether and how MPI has to evolve inordertomeettheperformanceandproductivitydemandsofExascalesystems. EuroMPI is the successor of the EuroPVM/MPI series, a ?agship conf- ence for this community, established as the premier international forum for - searchers,usersandvendorsto presenttheir latestadvancesinMPIandmessage th passingsystemingeneral.The17 EuropeanMPIusersgroupmeetingwasheld in Stuttgart during September 12-15,2010.The conferencewasorganizedbythe High Performance Computing Center Stuttgart at the University of Stuttgart.
