Processor architectures, high- speedinterconnectsandprogrammingmodelsareboundtogothroughdramatic changes.The MessagePassingInterface (MPI) is today the most successful and widespread programming model for parallel computing. An open question is whether MPI will evolve to meet the performance and productivity demands of Exascale systems. EuroMPI is the successor of the EuroPVM/MPI series, and is a key con- ference for this community, established as the premier international forum for researchers, users and vendors to present their latest advances in MPI and messagepassingsystemsingeneral.The18thEuropeanMPIusers’groupmeet- ing (EuroMPI 2011) was held in Santorini during September 18–21, 2011. The conference was organized by the University of Athens and the Innovative Computing Laboratory at the University of Tennessee. Previous conferences were held in Stuttgart (2010), Espoo (2009), Dublin (2008),Paris (2007), Bonn (2006),Sorrento (2005),Budapest (2004),Venice (2003), Linz (2002), Santorini (2001),Balatonfured(2000),Barcelona(1999),Liverpool(1998),Krakow(1997), Munich (1996), Lyon (1995) and Rome (1994). The EuroMPI 2011 program provided a balanced and interesting view on current developments and trends in message passing. The main topics were communication,I/O,networking,andimplementationissuesandimprovements; algorithms and tools; interaction with hardware; applications and performance evaluation;faulttolerance.Wereceived66papersubmissionsoutofwhichwese- lected28 papersfor presentation,and10posters withshortpresentations.Each paper had three or four reviews, contributing to the high quality of accepted papers. Two papers were selected as best contributions and were presented at plenary sessions: Tobias Hilbrich, Matthias S. Mueller, Martin Schulz and Bro- nisR.deSupinski,“OrderPreservingEventAggregationinTBONs”andAdam Moody, Dong Ahn and Bronis de Supinski, “Exascale Algorithms for General- izedMPI Comm split.”TheconferenceincludedthespecialsessiononImproving MPI User and Developer Interaction (IMUDI 2011) organized by Dries Kimpe and Jason Cope. The ProgramCommittee invitedfour outstandingresearchersto presentlec- tures on aspects of high-performance computing and message passing systems: Pete Beckman on “Exascale System Software Challenges – From Bare Metal to Applications,”GeorgeBosilcaon“WillMPIRemainRelevant?,”MichaelResch VI Preface on“ExperienceofaPRACECenter”andSudipDosanjhon“AchievingExascale Computing Through Hardware/SoftwareCo-design.” The Program and General Chairs would like to sincerely thank everybody who contributed to EuroMPI 2011, the authors, the reviewers, the participants and our sponsors Microsoft, ParTec, the Innovative Computing Laboratory at the University of Tennessee, Mellanox and the University of Athens. September 2011 Yiannis Cotronis Anthony Danalis Dimitris Nikolopoulos Jack J. Dongarra 1st Special Session on Improving MPI User and Developer Interaction IMUDI 2011 WhileformanyresearchersMPIitselfremainsanactiveresearchtopic,formany others it has become an invaluable tool to extract useful science from some of the most powerful machines available. Unfortunately these MPI application developers–andtheirhighlyvaluedexperienceandusecases–don’talwaysfind theirwaytotheEuroMPIconference.The1st SpecialSessiononImprovingMPI User and Developer Interaction (IMUDI 2011) aims to improve the balance by actively reaching out to the application developer communities. By evaluating the MPI standard from the perspective of the MPI end-user (application and library developers) we hope to provide application developers the opportunity tohighlightMPIissuesthatmightnotbeimmediatelyobvioustothedevelopers of the various MPI implementations, while at the same time enabling the MPI developers to solicit feedback regarding future MPI development, such as the MPI-3 standardization effort. For this year’s session, we invited Torsten Hoefler (University of Illinois at Urbana-Champaign)togiveakeynoteaddressonthesoftwaredevelopmentchal- lenges associated with parallel programming libraries using the MPI standard. We peer-reviewed and selected three papers from the six papers submitted to theIMUDI2011session.Thesepaperscoverseveraltopicsthataddresssoftware developmentchallengesassociatedwiththeMPIstandard:MPIinterfacesforin- terpreted languages,using C++ metaprogramming to simplify message-passing programming,andgroup-collectiveMPIcommunicatorcreation.Webelievethat thediscussionofthesetopicsintheIMUDI2011sessionwillbringtogetherMPI developers and MPI end-users, and help MPI users and implementors under- stand the challenges in developing MPI-based software and how to effectively use MPI in parallel software products. We are grateful for the support and help provided by our colleagues for this event. While we cannot list them all, we especially thank the EuroMPI 2011 conference organizers, including Jack Dongarra (University of Tennessee - Knoxville), Yiannis Cotronis (University of Athens), Anthony Danalis (Univer- sity of Tennessee - Knoxville), and Dimitris Nikolopoulos (University of Crete), for their invaluable feedback. We also thank the members of the IMUDI 2011 program committee for reviewing the session papers and their help in organiz- ing the session. The program committee for this year’s session included George Bosilca(TheUniversityofTennessee-Knoxville),ChristopherCarothers(Rens- selaer Polytechnic Institute), Terry Jones (Oak Ridge National Laboratory), Wei-KengLiao(NorthwesternUniversity),ShawnKim(PennsylvaniaStateUni- versity), Andreas Knu¨pfer (Technische Universita¨t Dresden), Quincey Koziol VIII Preface (The HDF5Group),JeffSquyres(CiscoSystems,Inc.),JesperTr¨aff(University ofVienna),andVenkatramVishwanath(ArgonneNationalLaboratory).Wealso thank William Gropp (University of Illinois at Urbana-Champaign)and Rajeev Thakur (Argonne National Laboratory)for their support.
