  • Exploiting a new level of DLP in multimedia applications 

    Corbal San Adrián, Jesús; Valero Cortés, Mateo; Espasa Sans, Roger (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    This paper proposes and evaluates MOM: a novel ISA paradigm targeted at multimedia applications. By fusing conventional vector ISA approaches together with more recent SIMD-like (Single Instruction Multiple Data) ISAs (such ...
  • Quantifying the benefits of SPECint distant parallelism in simultaneous multithreading architectures 

    Ortega Fernández, Daniel; Martel Pérez, Iván; Krishnan, Venkata; Ayguadé Parra, Eduard; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Text en actes de congrés
    Accés obert
    We exploit the existence of distant parallelism that future compilers could detect and characterise its performance under simultaneous multithreading architectures. By distant parallelism we mean parallelism that cannot ...
  • Command vector memory systems: high performance at low cost 

    Corbal San Adrián, Jesús; Espasa Sans, Roger; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 1998)
    Text en actes de congrés
    Accés obert
    The focus of this paper is on designing both a low cost and high performance, high bandwidth vector memory system that takes advantage of modern commodity SDRAM memory chips. To successfully extract the full bandwidth from ...
  • Effective usage of vector registers in decoupled vector architectures 

    Villa, Luis; Espasa Sans, Roger; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 1998)
    Text en actes de congrés
    Accés obert
    The paper presents a study of the impact of reducing the vector register size in a decoupled vector architecture. In traditional in-order vector architectures long vector registers have typically been the norm. The authors ...
  • Phoneme recognition with statisticasl modeling of the prediction of the error of neural networks 

    Freitag, Fèlix; Monte Moreno, Enrique (Robert H. Mannel and Jordi Robert-Ribes, 1998)
    Text en actes de congrés
    Accés obert
    This paper presents a speech recognition system which incorporates predictive neural networks. The neural networks are used to predict observation vectors of speech. The prediction error vectors are modeled on the state ...
  • Access to vectors in multi-module memories 

    Valero Cortés, Mateo; Peiron Guàrdia, Montse; Ayguadé Parra, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 1994)
    Text en actes de congrés
    Accés obert
    The poor bandwidth obtained from memory when conflicts arise in the modules or in the interconnection network degrades the performance of computers. Address transformation schemes, such as interleaving, skewing and linear ...
  • 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. ...
  • A Jacobi-based algorithm for computing symmetric eigenvalues and eigenvectors in a two-dimensional mesh 

    Royo Vallés, María Dolores; Valero García, Miguel; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 1998)
    Text en actes de congrés
    Accés obert
    The paper proposes an algorithm for computing symmetric eigenvalues and eigenvectors that uses a one-sided Jacobi approach and is targeted to a multicomputer in which nodes can be arranged as a two-dimensional mesh with ...
