(2015-11-13)
Analizamos las prestaciones y características de las distintas generaciones de procesadores gráficos desarrollados por Nvidia para la programación de aplicaciones de propósito general bajo CUDA, un paradigma nuevo que ... -
Project based learning on industrial informatics: applying IoT to urban garden
Hormigo-Aguilar, Javier; Rodríguez-Moreno, Andrés (2018-06-28)
The fast evolution of technologies forces teachers to trade content off for self-learning. PBL is one of the best ways to promote self-learning and simultaneously boost motivation. In this paper, we present our experience ... -
Quantifying the regeneration of bone tissue in biomedical images via Legendre moments
We investigate the use of Legendre moments as biomarkers for an efficient and accurate classification of bone tissue on images coming from stem cell regeneration studies. Regions of either existing bone, cartilage or ... -
Real-Time Unsupervised Object Localization on the Edge for Airport Video Surveillance.
Object localization is vital in computer vision to solve object detection or classification problems. Typically, this task is performed on expensive GPU devices, but edge computing is gaining importance in real-time ... -
Reducing overheads of dynamic scheduling on heterogeneous chips
Corbera-Peña, Francisco Javier; Rodríguez, Andrés; Asenjo-Plaza, Rafael; González-Navarro, María Ángeles; Vilches Reina, Antonio; Garzarán, María[et al.] (arXiv.org (Cornell University Library), 2015-01-19)
In recent processor development, we have witnessed the integration of GPU and CPUs into a single chip. The result of this integration is a reduction of the data communication overheads. This enables an efficient collaboration ... -
Reorganización de matrices en algoritmos de barrido radial sobre Modelos Digitales del Terreno
Es muy frecuente, en los sistemas de información geográfica que trabajan con modelos digitales del terreno, el uso de algoritmos de barrido radial para el estudio de variables asociadas a parámetros cuya magnitud decrece ... -

Reproducible SUmmation under HUB Format
Floating point reproducibility is a property claimed by programmers and end users. Half-Unit-Biased (HUB) is a new representation format in which the round to nearest is carried out by truncation, preventing any ... -
Robust tracking for augmented reality
González-Linares, José María; Guil-Mata, Nicolás; Ramos-Cózar, Julián (2015-06-17)
In this paper a method for improving a tracking algorithm in an augmented reality application is presented. This method addresses several issues to this particular application, like marker-less tracking and color constancy ... -
Runtime Aware Architectures; Barcelona Supercomputing Center at a glance
(2015-03-05)In the last few years, the traditional ways to keep the increase of hardware performance to the rate predicted by the Moore's Law have vanished. When uni-cores were the norm, hardware design was decoupled from the software ... -
Scalability Analysis of Signatures in Transactional Memory Systems
Signatures have been proposed in transactional memory systems to represent read and write sets and to decouple transaction conflict detection from private caches or to accelerate it. Generally, signatures are implemented ... -
Scheduling strategies for parallel patterns on heterogeneous architectures
(UMA Editorial, 2017)During the last decade, power consumption and energy efficiency have become key aspects in processor design. Nowadays, the power consumption is the principal limitation for further scaling of chip multiprocessors design ... -
A scheduling theory framework for GPU tasks efficient execution
Lázaro Muñoz, Antonio José; López Albelda, Bernabé; González-Linares, José María; Guil-Mata, Nicolás (2018-07-16)
Concurrent execution of tasks in GPUs can reduce the computation time of a workload by overlapping data transfer and execution commands. However it is difficult to implement an efficient run- time scheduler ... -
Simplified Floating-Point Units for High Dynamic Range Image and Video Systems
Hormigo-Aguilar, Javier; Villalba-Moreno, Julio (2015-06-29)
The upcoming arrival of high dynamic range image and video applications to consumer electronics will force the utilization of floating-point numbers on them. This paper shows that introducing a slight modification on ... -
