A Massively Parallel Algorithm for the Approximate Calculation of Inverse p-th Roots of Large Sparse Matrices
(Association for Computing Machinery (ACM), 2018-07)
Comunicació de congrés
Accés obertWe present the submatrix method, a highly parallelizable method for the approximate calculation of inverse p-th roots of large sparse symmetric matrices which are required in different scientific applications. Following ... -
Beyond the socket: NUMA-aware GPUs
(Association for Computing Machinery, 2017-10)
Comunicació de congrés
Accés obertGPUs achieve high throughput and power efficiency by employing many small single instruction multiple thread (SIMT) cores. To minimize scheduling logic and performance variance they utilize a uniform memory system and ... -
Breast cancer detection using machine learning with thermograms in an edge computing scenario
(Association for Computing Machinery (ACM), 2021)
Comunicació de congrés
Accés restringit per política de l'editorialThe second cause of death in the world is cancer. Although breast cancer is the more common cause of death among women, the chance of survival can be increased by detecting cancer in the early stages. For this aim, there ... -

Comunicació de congrés
Accés obertComputational fluid and particle dynamics simulations (CFPD) are of paramount importance for studying and improving drug effectiveness. Computational requirements of CFPD codes involves high-performance computing (HPC) ... -
Evaluation of adherence to nutritional intervention through trajectory analysis
(2017-05)
Article
Accés obertClassical Pre-Post Intervention Studies are often analyzed using traditional statistics. Nevertheless, the nutritional interventions have small effects on the metabolism and traditional statistics are not enough to detect ... -
Iteration-fusing conjugate gradient
(Association for Computing Machinery (ACM), 2017-06)
Comunicació de congrés
Accés obertThis paper presents the Iteration-Fusing Conjugate Gradient (IFCG) approach which is an evolution of the Conjugate Gradient method that consists in i) letting computations from different iterations to overlap between them ... -
libPRISM: an intelligent adaptation of prefetch and SMT levels
(Association for Computing Machinery (ACM), 2017)
Text en actes de congrés
Accés obertCurrent microprocessors include several knobs to modify the hardware behavior in order to improve performance under different workload demands. An impractical and time consuming offline profiling is needed to evaluate the ... -
Multidimensional blocking in UPC
(Springer, 2008-02)
Article
Accés restringit per política de l'editorialPartitioned Global Address Space (PGAS) languages offer an attractive, high-productivity programming model for programming large-scale parallel machines. PGAS languages, such as Unified Parallel C (UPC), combine the ... -
Optimizing the exploitation of multicore processors and GPUs with OpenMP and OpenCL
(Springer, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, we present OMPSs, a programming model based on OpenMP and StarSs, that can also incorporate the use of OpenCL or CUDA kernels. We evaluate the proposal on three different architectures, SMP, Cell/B.E. and ... -
Terrain prickliness: theoretical grounds for high complexity viewsheds
(2021)
Text en actes de congrés
Accés obertAn important task when working with terrain models is computing viewsheds: the parts of the terrain visible from a given viewpoint. When the terrain is modeled as a polyhedral terrain, the viewshed is composed of the union ...
