Hybrid parallel programming with tasks

Autor: J. Mark Bull, Jiehong Yu

This technical report is an introduction to using a hybrid parallel programming model that combines MPI with OmpSs or OpenMP dependent tasks. This model allows both computation and communication to be expressed using a coarse-grained dataflow approac

From the world wide web, to genomics, to traffic analysis, graphs are central to many scientific, engineering, and societal endeavours. Therefore an important question is what hardware technologies are most appropriate to invest in and use for proces

The vertex-centric programming model, designed to improve the programmability in graph processing application writing, has attracted great attention over the years. Multiple shared memory frameworks that have implemented the vertex-centric interface

Generalisation of Recursive Doubling for AllReduce

Autor: Stephen Booth, Mark Bull, Martin Ruefenacht

Publikováno v: EuroMPI

The performance of AllReduce is crucial at scale. The recursive doubling with pairwise exchange algorithm theoretically achieves O(log2 N) scaling for short messages with N peers, but is limited by improvements in network latency. A multi-way exchang
