An extension to the OpenMP task construct to add support for reductions in while-loops and general-recursive algorithms.

Abstract

The wide adoption of parallel processing hardware in mainstream computing as well as the raising interest for efficient parallel programming in the developer community increase the demand for parallel programming model support for common algorithmic patterns. In this work we present an extension to the OpenMP task construct to add support for reductions in while-loops and general-recursive algorithms. Further we discuss implications on the OpenMP standard and present a prototype implementation in OmpSs. Benchmark results confirm applicability of this approach and scalability on current SMP systems.

News & Events

OpenMP F2F 2018-2

A good week in Bordeaux, France focused on closing different open topics in the specification and many of those who have been discussed during past weeks have been shaping up and they are in good condition to go through the committee’s votes.

 OpenMP tasking at ISC 2018

An advanced tutorial using the tasking model of the OpenMP standard. This course includes recent addition of OpenMP 4.5, being all the lecturers part of the OpenMP language committee.

 INTERTWinE F2F 2018

Last Face to Face meeting before the end of the project and we have report the work progress for the different work packages and several technical sessions in a one-and-a-half-day meeting in Stockholm, Sweden.

 PATC (May, 2017)

The tutorial will motivate the audience on the need for portable, efficient programming models that put less pressure on program developers while still getting good performance for clusters and clusters with GPUs.

 OpenMP F2F 2018-1

We have done a very good progress towards the future of the OpenMP 5.0 specification. We have discussed many issues and voted several tickets that finally have already been included in the specification (or will do in the short term).

 OmpSs demos at SC 2017

Two short demos at the exhibition center showing the basic concepts of the OmpSs programming model. See you in the BSC booth (#1975).
