H.264/AVC inter prediction for heterogeneous computing systems
Springer (2013)H.264/AVC is the latest standard for video compression and is a significant advance, but at the expense of increasing computing needs. Recently, the progress of GPUs has attracted considerable attention because they are ... -
H.264/AVC inter prediction on accelerator-based multi-core systems
Springer (2013)The AVC video coding standard adopts variable block sizes for inter frame coding to increase compression efficiency, among other new features. As a consequence of this, an AVC encoder has to employ a complex mode decision ... -
Harvesting Energy in ILUPACK via Slack Elimination
(2017-07-05)We develop a new energy-aware methodology to improve the energy consumption of a task-parallel preconditioned Conjugate Gradient iter- ative solver on a Haswell-EP Intel Xeon. This technique leverages the power-saving ... -
Help Hamilton: un juego para mejorar el aprendizaje en Bases de datos
JENUI Editores (2022)En este artículo se describe un juego llevado a cabo en una asignatura de Bases de datos. El juego requiere aplicar conocimientos del lenguaje SQL y también de diseño de bases de datos relacionales. La experiencia ha ... -
Hierarchical approach for deriving a reproducible unblocked LU factorization
Sage (2019-03-17)We propose a reproducible variant of the unblocked LU factorization for graphics processor units (GPUs). For this purpose, we build upon Level-1/2 BLAS kernels that deliver correctly-rounded and reproducible results for ... -
High performance and energy efficient inference for deep learning on multicore ARM processors using general optimization techniques and BLIS
Elsevier (2022-03-22)We evolve PyDTNN, a framework for distributed parallel training of Deep Neural Networks (DNNs), into an efficient inference tool for convolutional neural networks. Our optimization process on multicore ARM processors ... -

Springer Science+Business Media (2011-12)This special issue collects research papers selected among those presented at the second minisymposium “HPC applied to Computational Problems in Science and Engineering” which was held in June 2010, in Almeria, Spain. ... -
High-performance reconstruction of CT medical images by using out-of-core methods in GPU
Elsevier (2022-03-02)Background and objective:Since Computed Tomography (CT) is one of the most widely used medical imaging tests, it is essential to work on methods that reduce the radiation the patient is exposed to. Although there are several ... -
Highly sensitive and ultrafast read mapping for RNA-seq analysis
Oxford University Press (2016)As sequencing technologies progress, the amount of data produced grows exponentially, shifting the bottleneck of discovery towards the data analysis phase. In particular, currently available mapping solutions for RNA-seq ... -
Householder QR Factorization With Randomization for Column Pivoting (HQRRP)
Society for Industrial and Applied Mathematics (2017)A fundamental problem when adding column pivoting to the Householder QR fac- torization is that only about half of the computation can be cast in terms of high performing matrix- matrix multiplications, which greatly ... -
How deeply do we include robotic agents in the self?
World Scientific Publishing (2013)In human–human interactions, a consciously perceived high degree of self–other overlap is associated with a higher degree of integration of the other person's actions into one's own cognitive representations. Here, we ... -
Hybrid static–dynamic selection of implementation alternatives in heterogeneous environments
Springer (2019-09)With the emergence of heterogeneous architectures, developing parallel software has become an increasingly complex task. The ability of using multiple devices in a single application, such as CPUs, accelerators, or ... -
