Exploiting Task and Data Parallelism in ILUPACK's Preconditioned CG Solver on NUMA Architectures and Many-core Accelerators
Aliaga Estellés, José Ignacio; Badía Sala, Rosa María; Barreda Vayá, Maria; Bollhöffer, Matthias; Dufrechou, Ernesto; Ezzatti, Pablo; Quintana-Orti, Enrique S. Elsevier (2016-05)We present specialized implementations of the preconditioned iterative linear system solver in ILUPACK for Non-Uniform Memory Access (NUMA) platforms and many-core hardware co-processors based on the Intel Xeon Phi and ... -
Exploring large macromolecular functional motions on clusters of multicore processors
López Blanco, José R.; Reyes, Ruymán; Aliaga Estellés, José Ignacio; Badía Sala, Rosa María; Chacón, Pablo; Quintana-Orti, Enrique S. Elsevier (2013-08)Normal modes in internal coordinates (IC) furnish an excellent way to model functional collective motions of macromolecular machines, but exhibit a high computational cost when applied to large-sized macromolecules. In ... -
Extending OpenMP to Survive the Heterogeneous Multi-Core Era
Ayguadé, Eduardo; Badía Sala, Rosa María; Bellens, Pieter; Cabrera, Daniel; Durán, Alejandro; Ferrer, Roger; González, Marc; Igual, Francisco; Jiménez González, Daniel; Labarta Mancho, Jesús; Martinell, Luis; Martorell, Xavier; Mayo, Rafael; Pérez, Josep M.; Planas, Judit; Quintana-Orti, Enrique S. Springer US (2010)This paper advances the state-of-the-art in programming models for exploiting task-level parallelism on heterogeneous many-core systems, presenting a number of extensions to the OpenMP language inspired in the StarSs ... -
Leveraging task-parallelism in message-passing dense matrix factorizations using SMPSs
Martín, Alberto F.; Reyes, Ruymán; Badía Sala, Rosa María; Quintana-Orti, Enrique S. Elsevier (2014)In this paper, we investigate how to exploit task-parallelism during the execution of the Cholesky factorization on clusters of multicore processors with the SMPSs programming model. Our analysis reveals that the major ... -
Parallelizing dense and banded linear algebra libraries using SMPSs
Badía Sala, Rosa María; Herrero, Josep R.; Labarta Mancho, Jesús; Pérez, Josep M.; Quintana-Orti, Enrique S.; Quintana-Ortí, Gregorio John Wiley (2009-12-25)The promise of future many-core processors, with hundreds of threads running concurrently, has led the developers of linear algebra libraries to rethink their design in order to extract more parallelism, further exploit ...
