Main results
A long series of software-engineering and algorithmic contributions to the efficient implementation the Message Passing Interface (MPI) standard, highlighting potential and problems of a standardized interface for the convenient and efficient utilization of current and next-generation supercomputer systems.
Specific contributions include: round-optimal broadcast algorithms, best-known reduction and prefix-sums algorithms, realization of process reordering by communication graph partitioning, as well as efficient, vectorized handling of structured, non-consecutive datalayouts.
