2nd special session on improving MPI user and developer interaction (IMUDI 2012)

While for many researchers MPI itself remains an active research topic, for many others it has become an invaluable tool to extract useful science from some of the most powerful machines available. Unfortunately these MPI application developers --- and their highly valued experience and use cases --- do not always find their way to the EuroMPI conference. The 2nd Special Session on Improving MPI User and Developer Interaction (IMUDI 2012) once again 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 to highlight MPI issues that might not be immediately obvious to the developers 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.
