• Acelerando los momentos de Zernike sobre Kepler 

      Ruiz, Antonio; Ujaldón, Manuel (2014-05-02)
      Este trabajo analiza las características más avanzadas de la arquitectura Kepler de Nvidia, principalmente el paralelismo dinámico para el lanzamiento de kernels desde la GPU y la planificación de hilos con Hyper-Q. ...
    • DNA Sequences Alignment in Multi-GPUs: Energy Payoff on Speculative Executions 

      Pérez-Serrano, Jesús; Sandes, Edans; Melo, Alba; Ujaldón, Manuel (2017-05-30)
      We present a performance per watt analysis of CUDAlign 4.0, a parallel strategy to obtain the optimal alignment of huge DNA se- quences in multi-GPU platforms using the exact Smith-Waterman method. Speed-up factors and ...
    • Entropy-based High Performance Computation of Boolean SNP-SNP Interactions Using GPUs 

      Riveros, Carlos; Ujaldón, Manuel; Pablo, Moscato (2014-05-02)
      It is being increasingly accepted that traditional statistical Single Nucleotide Polymorphism (SNP) analysis of Genome-Wide Association Studies (GWAS) reveals just a small part of the heritability in complex diseases. ...
    • GPUs para HPC: Logros y perspectivas futuras 

      Ujaldón, Manuel (2013-10-18)
      Hace una década comenzábamos a mejorar las primeras aplicaciones científicas en GPUs utilizando Cg y OpenGL. Ahora CUDA y OpenCL han tomado el relevo, marcando un ritmo vertiginoso en la aceleración de códigos procedentes ...
    • Quantifying the regeneration of bone tissue in biomedical images via Legendre moments 

      Lachiondo, José Antonio; Ujaldón, Manuel; Berretta, Regina; Moscato, Pablo (2013-10-21)
      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 ...
    • Smith-Waterman Acceleration in Multi-GPUs: A Performance per Watt Analysis 

      Pérez-Serrano, Jesús; Sandes, Edans; Melo, Alba; Ujaldón, Manuel (Springer, 2017)
      We present a performance per watt analysis of CUDAlign 4.0, a parallel strategy to obtain the optimal alignment of huge DNA se- quences in multi-GPU platforms using the exact Smith-Waterman method. Speed-up factors and ...
