English abstract:
MPI, the Message-Passing Interface, owes a large part of its pervasiveness to the orthogonality and completeness of the specification; another large part to the existence of efficient implementations of the full standard. We examine key concepts of the collective communication model of MPI (including extensions in the MPI 3.0 specification) and their relations to the derived datatype mechanism for describing structured application data. Together with the mechanisms for creating process subsets, these models provide still unreaped descriptive and performance advantages for applications and libraries, while on the other hand still posing significant implementation challenges.
