The EuroMPI conference is the preeminent meeting for users, developers and researchers to interact and discuss new developments and applications of the Message Passing Interface (MPI). This includes new proposed concepts and extensions to the MPI standard, libraries and languages built on top of MPI, interfaces to other standards in parallel programming, applications and optimizations to new architectures and networks, novel algorithms, and tools, with particular focus on quality, portability, performance, and scalability. The annual meeting has a long, rich tradition, and has been held since 1994.
