    Article
    Accés restringit per política de l'editorial
    As a result of the rapid growth of Cloud Computing, several Cloud middleware solutions for the creation and automated management of virtual appliances have been released. Generally, these solutions offer some predefined ...
  • Compact finite difference modeling of 2-D acoustic wave propagation 

    Córdova, Luis; Rojas, Otilio; Otero Calviño, Beatriz; Castillo, Jose (2016-03-15)
    Article
    Accés obert
    We present two fourth-order compact finite difference (CFD) discretizations of the velocity–pressure formulation of the acoustic wave equation in 2-D rectangular grids. The first method uses standard implicit CFD on nodal ...
  • Cost-conscious strategies to increase performance of numerical programs on agressive VLIW architectures 

    López Álvarez, David; Llosa Espuny, José Francisco; Valero Cortés, Mateo; Ayguadé Parra, Eduard (2001-10)
    Article
    Accés obert
    Loops are the main time-consuming part of numerical applications. The performance of the loops is limited either by the resources offered by the architecture or by recurrences in the computation. To execute more operations ...
  • Thread assignment of multithreaded network applications in multicore/multithreaded processors 

    Radojkovic, Petar; Cakarevic, Vladimir; Verdú Mulà, Javier; Pajuelo González, Manuel Alejandro; Cazorla Almeida, Francisco Javier; Nemirovsky, Mario; Valero Cortés, Mateo (2013-12)
    Article
    Accés obert
    The introduction of multithreaded processors comprised of a large number of cores with many shared resources makes thread scheduling, and in particular optimal assignment of running threads to processor hardware contexts ...
  • Revisiting distance-based record linkage for privacy-preserving release of statistical datasets 

    Herranz Sotoca, Javier; Nin Guerrero, Jordi; Rodríguez, Pablo; Tassa, Tamir (Elsevier, 2015-07-17)
    Article
    Accés restringit per política de l'editorial
    Statistical Disclosure Control (SDC, for short) studies the problem of privacy-preserving data publishing in cases where the data is expected to be used for statistical analysis. An original dataset T containing sensitive ...
  • ParaDIME: Parallel distributed infrastructure for minimization of energy for data centers 

    Rethinagiri, Santhosh Kumar; Palomar Pérez, Óscar; Sobe, Anita; Yalcin, Gulay; Knauth, Thomas; Titos Gil, Rubén; Prieto, Pablo; Schneegaß, Malte; Cristal Kestelman, Adrián; Unsal, Osman Sabri; Felber, Pascal; Fetzer, Christof; Milojevic, Dragomir (2015-11-01)
    Article
    Accés restringit per política de l'editorial
    Dramatic environmental and economic impact of the ever increasing power and energy consumption of modern computing devices in data centers is now a critical challenge. On the one hand, designers use technology scaling as ...
  • Thread assignment in multicore/multithreaded processors: A statistical approach 

    Radojkovic, Petar; Carpenter, Paul M.; Moreto Planas, Miquel; Cakarevic, Vladimir; Verdú Mulà, Javier; Pajuelo González, Manuel Alejandro; Cazorla Almeida, Francisco Javier; Nemirovsky, Mario; Valero Cortés, Mateo (2016-01-01)
    Article
    Accés obert
    The introduction of multicore/multithreaded processors, comprised of a large number of hardware contexts (virtual CPUs) that share resources at multiple levels, has made process scheduling, in particular assignment of ...
  • GeoSRS: a hybrid social recommender system for geolocated data 

    Capdevila Pujol, Joan; Arias Vicente, Marta; Arratia Quesada, Argimiro Alejandro (2016-04-01)
    Article
    Accés obert
    All right sreserved. We present GeoSRS, a hybrid recommender system for a popular location-based social network (LBSN), in which users are able to write short reviews on the places of interest they visit. Using state-of-the-art ...
  • A new mimetic scheme for the acoustic wave equation 

    Solano, Freysimar; Guevara-Jordan, Juan; Rojas, Otilio; Otero Calviño, Beatriz; Rodriguez, R. (2016-03-15)
    Article
    Accés obert
    A new mimetic finite difference scheme for solving the acoustic wave equation is presented. It combines a novel second order tensor mimetic discretizations in space and a leapfrog approximation in time to produce an explicit ...
  • Runtime-aware architectures: a first approach 

    Valero Cortés, Mateo; Moreto Planas, Miquel; Casas Guix, Marc; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (2014)
    Article
    Accés obert
    In the last few years, the traditional ways to keep the increase of hardware performance at the rate predicted by Moore's Law have vanished. When uni-cores were the norm, hardware design was decoupled from the software ...
