Opis

The current trend in the state-of-the-art infrastructure for computational s- ence is dominated by two concepts: multicore processors and a massive number ofprocessorsinsupercomputers.Thenumberofcoresinprocessorshasincreased rapidly in last few years and this has driven the number of processors in the supercomputers to new scales. As the scale of the supercomputers increases so doesthedominanceofmessagepassingbetweenprocessors.TheEuroPVM/MPI conferenceseries is the premier researcheventfor high-performanceparallelp- gramminginthemessage-passingparadigm.Applicationsusingparallelmessa- passing programming, pioneered in this research community, are having sign- icant impact in the areas of computational science, such as bioinformatics, - mosphericscience, chemistry, physics, astronomy, medicine, bankingand?nance, energy, etc. EuroPVM/MPI is a ?agship conference for this community, established as the premier international forum for researchs, users and vendors to present their latest advances in MPI and PVM. EuroPVM/MPI is the forum where fun- mental aspects of message passing, implementations, standards, benchmarking, performance and new techniques are presented and dicussed by researchers, - velopers and users from academia and industry. The16thEuropeanPVM/MPIUsers'GroupMeeting washeldinEspood- ing September 7-10,2009.The conference wasorganizedby the CSC- IT Center ? for Science and the Department of Information Technology at Abo Akademi University. The previous conferences were held in Dublin (2008), Paris (2007), Bonn(2006), Sorrento(2005), Budapest(2004), Venice(2003), Linz(2002), S- torini (2001), Balatonfured (2000), Barcelona (1999), Liverpool (1998), Krakow (1997), Munich (1996), Lyon (1995) and Rome (1994). The main topics of the meeting were message-passing interface (MPI) p- formance issues in very large systems, MPI program veri?cation and MPI on multi-core architectures.
