Tuning MPI Collectives by Verifying Performance Guidelines
Sascha Hunold, Alexandra Carpen-Amarie
MPI collective operations provide a standardized interface for performing data movements within a group of processes. The efficiency of collective communication operations depends…
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…
MPI Benchmarking Revisited: Experimental Design and Reproducibility
Sascha Hunold, Alexandra Carpen-Amarie
The Message Passing Interface (MPI) is the prevalent programming model used on today's supercomputers. Therefore, MPI library developers are looking for the best possible performan…
An Algorithm for File Transfer Scheduling in Grid Environments
Alexandra Carpen-Amarie, Mugurel Ionut Andreica, Valentin Cristea
This paper addresses the data transfer scheduling problem for Grid environments, presenting a centralized scheduler developed with dynamic and adaptive features. The algorithm offe…
