  • Main memory in HPC: do we need more, or could we live with less? 

    Zivanovic, Darko; Pavlovic, Milan; Radulovic, Milan; Shin, Hyunsung; Son, Jongpil; McKee, Sally A.; Carpenter, Paul M.; Radojkovic, Petar; Ayguadé Parra, Eduard (2017-03)
    Article
    Accés obert
    An important aspect of High-Performance Computing (HPC) system design is the choice of main memory capacity. This choice becomes increasingly important now that 3D-stacked memories are entering the market. Compared with ...
  • BIGNASim: a NoSQL database structure and analysis portal for nucleic acids simulation data 

    Hospital, Adam; Andrio, Pau; Cugnasco, Cesare; Codo, Laia; Becerra Fontal, Yolanda; Dans, Pablo D.; Battistini, Federica; Torres Viñals, Jordi; Goñi, Ramon; Orozco, Modesto; Gelpi, Josep Lluis (2016-01-04)
    Article
    Accés obert
    Molecular dynamics simulation (MD) is, just behind genomics, the bioinformatics tool that generates the largest amounts of data, and that is using the largest amount of CPU time in supercomputing centres. MD trajectories ...
  • Fuzzy memoization for floating-point multimedia applications 

    Álvarez Martínez, Carlos; Corbal San Adrián, Jesús; Valero Cortés, Mateo (2005-07)
    Article
    Accés obert
    Instruction memoization is a promising technique to reduce the power consumption and increase the performance of future low-end/mobile multimedia systems. Power and performance efficiency can be improved by reusing instances ...
  • Explaining dynamic cache partitioning speed ups 

    Moreto Planas, Miquel; Cazorla, Francisco; Ramírez Bellido, Alejandro; Valero Cortés, Mateo (2007-01)
    Article
    Accés obert
    Cache partitioning has been proposed as an interesting alternative to traditional eviction policies of shared cache levels in modern CMP architectures: throughput is improved at the expense of a reasonable cost. However, ...
  • Coarse grain parallelization of deep neural networks 

    González Tallada, Marc (2016-08-01)
    Article
    Accés restringit per política de l'editorial
    Deep neural networks (DNN) have recently achieved extraordinary results in domains like computer vision and speech recognition. An essential element for this success has been the introduction of high performance computing ...
  • An analytical model for Loc/ID mappings caches 

    Coras, Florin-Tudorel; Domingo Pascual, Jordi; Lewis, Darrel; Cabellos Aparicio, Alberto (2016-02)
    Article
    Accés obert
    Concerns regarding the scalability of the interdomain routing have encouraged researchers to start elaborating a more robust Internet architecture. While consensus on the exact form of the solution is yet to be found, the ...
  • Enlarging instruction streams 

    Santana Jaria, Oliverio J.; Ramírez Bellido, Alejandro; Valero Cortés, Mateo (2007-10)
    Article
    Accés obert
    The stream fetch engine is a high-performance fetch architecture based on the concept of an instruction stream. We call a sequence of instructions from the target of a taken branch to the next taken branch, potentially ...
  • Automated construction and analysis of political networks via open government and media sources 

    García-Olano, Diego; Arias Vicente, Marta; Larriba Pey, Josep (2016)
    Text en actes de congrés
    Accés obert
    We present a tool to generate real world political networks from user provided lists of politicians and news sites. Additional output includes visualizations, interactive tools and maps that allow a user to better understand ...
  • Exploiting path parallelism in logic programming 

    Tubella Murgadas, Jordi; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 1995)
    Text en actes de congrés
    Accés obert
    This paper presents a novel parallel implementation of Prolog. The system is based on Multipath, a novel execution model for Prolog that implements a partial breadth-first search of the SLD-tree. The paper focusses on the ...
  • A methodology for user-oriented scalability analysis 

    Royo Vallés, María Dolores; Valero García, Miguel; González Colás, Antonio María; Marí, Carme (Institute of Electrical and Electronics Engineers (IEEE), 1997)
    Text en actes de congrés
    Accés obert
    Scalability analysis provides information about the effectiveness of increasing the number of resources of a parallel system. Several methods have been proposed which use different approaches to provide this information. ...
