Since 1994, the EuroMPI conference is the preeminent meeting for users, developers and researchers to interact and discuss new developments and applications of message-passing parallel computing, in particular in and related to the Message Passing Interface (MPI). This includes parallel programming interfaces, libraries and languages, architectures, networks, algorithms, tools, applications, and High Performance Computing with particular focus on quality, portability, performance and scalability. EuroMPI is not exclusively dedicated to MPI, but also welcomes contributions on extensions or alternative interfaces for high-performance homogeneous/heterogeneous/hybrid systems, benchmarks, tools, parallel I/O, fault tolerance, and parallel applications using MPI and other interfaces. Through the presentation of contributed papers, posters and invited talks, the EuroMPI meeting always provides fine opportunities for attendees to interact and share ideas and experiences to contribute to the improvement and furthering of message-passing and related parallel programming paradigms.
