A data relocation approach for terrain surface analysis on multi-GPU systems: a case study on the total viewshed problem.
Sánchez Fernández, Andrés Jesús; Romero-Gómez, Luis Felipe
; Bandera-Burgueño, Gerardo; Tabik, Siham (Taylor & Francis, 2020-12-04)
Digital Elevation Models (DEMs) are important datasets for modelling line-of-sight phenomena such as radio signals, sound waves and human vision. These are commonly analysed using rotational sweep algorithms. However, ... -
Accelerating Sequence Alignments Based on FM-Index Using the Intel KNL Processor
Herruzo-Ruiz, José Manuel; González-Navarro, Sonia; Ibáñez, Pablo; Viñals, Victor; Alastruey-Benedé, Jesús; Óscar, Plata[et al.] (IEEE/ACM TRANSACTIONS ON COMPUTATIONAL BIOLOGY AND BIOINFORMATICS,, 2020-07-01)
FM-index is a compact data structure suitable for fast matches of short reads to large reference genomes. The matching algorithm using this index exhibits irregular memory access patterns that cause frequent cache misses, ... -
Energy-based tuning of convolution neural networks on multi-GPUs
Castro Payán, Francisco Manuel; Guil-Mata, Nicolás; Marín Jiménez, Manuel Jesús; Pérez-Serrano, Jesús; Ujaldon-Martínez, Manuel (Wiley, 2019-11)
Deep Learning (DL) applications are gaining momentum in the realm of Artificial Intelligence, particularly after GPUs have demonstrated remarkable skills for accelerating their challenging computational requirements. Within ... -
Energy-based tuning of metaheuristics for molecular docking on multi-GPUs
Pérez-Serrano, Jesús; Imbernón, Baldomero; Cecilia, José María; Ujaldon-Martínez, Manuel (Wiley, 2018-09)
Virtual Screening (VS) methods simulate molecular interactions in silico to look for the best chemical compound that interacts with a given molecular target. VS is becoming increasingly popular to accelerate the drug ... -
Fisher Motion Descriptor for Multiview Gait Recognition.
Castro, Francisco M.; Marín Jiménez, Manuel Jesús; Guil-Mata, Nicolás; Muñoz-Salinas, Rafael (World Scientific, 2017)
This paper aims to identify individuals by analyzing their gait using motion descriptors based on densely sampled short-term trajectories, instead of traditional binary silhouettes. The approach leverages advanced people ... -
Hardware Signature Designs to Deal With Asymmetry in Transactional Data Sets
Quislant-del-Barrio, Ricardo; Gutiérrez-Carrasco, Eladio Damián; Plata-González, Óscar Guillermo; López-Zapata, Emilio (IEEE, 2013)
Transactional Memory (TM) systems must track memory accesses made by concurrent transactions in order to detect conflicts. Many TM implementations use signatures for this purpose, which summarize reads and writes in ... -
Lazy Irrevocability for Best-Effort Transactional Memory Systems
Quislant-del-Barrio, Ricardo; Gutiérrez-Carrasco, Eladio Damián; López-Zapata, Emilio; Plata-González, Óscar Guillermo (IEEE, 2017)
IBM and Intel now offer commercial systems with Transactional Memory (TM), a programming paradigm whose aim is to facilitate concurrent programming while maximizing parallelism. These TM systems are implemented in hardware ... -
miRNA as biomarker in lung cancer
Salcedo Lobera, Esperanza; Arroyo Varela, Macarena; Larrosa-Jiménez, Rafael; Bautista-Moreno, Rocío (Springer Nature, 2023-08-29)
Lung cancer has a high prevalence and mortality due to its late diagnosis and limited treatment, so it is essential to find biomarkers that allow a faster diagnosis and improve the survival of these patients. In this sense, ... -
Multimodal feature fusion for CNN-based gait recognition: an empirical comparison
Castro, Francisco M.; Marín-Jiménez, Manuel J.; Guil-Mata, Nicolás; Pérez de la Blanca, Nicolás (Springer London, 2020)
This paper focuses on identifying people based on their gait using a non-invasive approach. Traditional methods rely on gait signatures derived from binary energy maps, which introduce noise. Instead, the authors explore ... -
Multimodal features fusion for gait, gender and shoes recognition
Castro Payán, Francisco Manuel; Marín-Jiménez, Manuel J.; Guil-Mata, Nicolás (Springer, 2016)
This paper evaluates how fusing multimodal features (audio, RGB, and depth) can enhance the task of gait recognition, as well as gender and shoe recognition. While most previous research has focused on visual descriptors ... -
On how to improve tracklet-based gait recognition systems
Marín-Jiménez, Manuel J.; Castro Payán, Francisco Manuel; Carmona-Poyato, Ángel; Guil-Mata, Nicolás (Elsevier, 2015-12-15)
Abstract Recently, short-term dense trajectories features (DTF) have shown state-of-the-art results in video recognition and retrieval. However, their use has not been extensively studied on the problem of gait recognition. ... -
Teaching the Cache Memory System Using a Reconfigurable Approach
Quislant-del-Barrio, Ricardo; Herruzo, Ezequiel; Plata-González, Óscar Guillermo; Benavides, Jose Ignacio; Zapata, Emilio L. (IEEE, 2008)
This paper presents a tool that simulates a reconfigurable cache whose parameters can be changed at runtime through a special instruction at the instruction set architecture (ISA) level. The proposed tool simulates a cache ...
