Advanced Synchronization Techniques for Task-based Runtime Systems
David Álvarez, Kevin Sala, Marcos Maroñas +2
Task-based programming models like OmpSs-2 and OpenMP provide a flexible data-flow execution model to exploit dynamic, irregular and nested parallelism. Providing an efficient impl…
Enhancing Resource Management through Prediction-based Policies
Antoni Navarro, Arthur F. Lorenzon, Eduard Ayguadé +1
Task-based programming models are emerging as a promising alternative to make the most of multi-/many-core systems. These programming models rely on runtime systems, and their goal…
Extending the OpenCHK Model with Advanced Checkpoint Features
Marcos Maroñas, Sergi Mateo, Kai Keller +3
One of the major challenges in using extreme scale systems efficiently is to mitigate the impact of faults. Application-level checkpoint/restart (CR) methods provide the best trade…
DMR API: Improving cluster productivity by turning applications into malleable
Sergio Iserte, Rafael Mayo, Enrique S. Quintana-Orti +2
Adaptive workloads can change on--the--fly the configuration of their jobs, in terms of number of processes. In order to carry out these job reconfigurations, we have designed a me…
Worksharing Tasks: An Efficient Way to Exploit Irregular and Fine-Grained Loop Parallelism
M. Maronas, K. Sala, S. Mateo +2
Shared memory programming models usually provide worksharing and task constructs. The former relies on the efficient fork-join execution model to exploit structured parallelism; wh…
HDOT -- an Approach Towards Productive Programming of Hybrid Applications
Jan Ciesko, Pedro J. Martínez-Ferrer, Raúl Peñacoba Veigas +2
MPI applications matter. However, with the advent of many-core processors, traditional MPI applications are challenged to achieve satisfactory performance. This is due to the inabi…
Integrating Blocking and Non-Blocking MPI Primitives with Task-Based Programming Models
Kevin Sala, Xavier Teruel, Josep M. Perez +3
In this paper we present the Task-Aware MPI library (TAMPI) that integrates both blocking and non-blocking MPI primitives with task-based programming models. The TAMPI library leve…
