MPI Derived Datatypes: Performance Expectations and Status Quo
Alexandra Carpen-Amarie, Sascha Hunold, Jesper Larsson Träff
We examine natural expectations on communication performance using MPI derived datatypes in comparison to the baseline, "raw" performance of communicating simple, non-contiguous da…
Message-Combining Algorithms for Isomorphic, Sparse Collective Communication
Jesper Larsson Träff, Alexandra Carpen-Amarie, Sascha Hunold +1
Isomorphic (sparse) collective communication is a form of collective communication in which all involved processes communicate in small, identically structured neighborhoods of oth…
PGMPI: Automatically Verifying Self-Consistent MPI Performance Guidelines
Sascha Hunold, Alexandra Carpen-Amarie, Felix Donatus Lübbe +1
The Message Passing Interface (MPI) is the most commonly used application programming interface for process communication on current large-scale parallel systems. Due to the scale…
