  • Toward sustainable data centers: a comprehensive energy management strategy 

    Guitart Fernández, Jordi (2016-06-28)
    Article
    Accés restringit per política de l'editorial
    Data centers are major contributors to the emission of carbon dioxide to the atmosphere, and this contribution is expected to increase in the following years. This has encouraged the development of techniques to reduce the ...
  • Shared resource aware scheduling on power-constrained tiled many-core processors 

    Jha, Sudhanshu Shekhar; Heirman, Wim; Falcón Samper, Ayose Jesus; Tubella Murgadas, Jordi; González Colás, Antonio María; Eeckhout, Lieven (2017-02-01)
    Article
    Accés restringit per política de l'editorial
    Power management through dynamic core, cache and frequency adaptation is becoming a necessity in today’s power-constrained many-core environments. Unfortunately, as core count grows, the complexity of both the adaptation ...
  • On the influence of creativity in basic programming learning at a first-year Engineering course 

    Pérez Poch, Antoni; Olmedo Torre, Noelia; Sánchez Carracedo, Fermín; Salán Ballesteros, Maria Núria; López Álvarez, David (Tempus Publications, 2016-10)
    Article
    Accés obert
    Teaching fundamentals of programming is a complex task that involves the students’ acquisition of diverse knowledge and skills. It is also well known that programming often requires a certain degree of creativity. There ...
  • Network unfairness in dragonfly topologies 

    Fuentes, Pablo; Vallejo, Enrique; Camarero, Cristóbal; Beivide Palacio, Ramon; Valero Cortés, Mateo (2016-12)
    Article
    Accés restringit per política de l'editorial
    Dragonfly networks arrange network routers in a two-level hierarchy, providing a competitive cost-performance solution for large systems. Non-minimal adaptive routing (adaptive misrouting) is employed to fully exploit the ...
  • Impact of parameter variations on circuits and microarchitecture 

    Unsal, Osman Sabri; Tschanz, James W.; Bowman, Keith; De, Vivek; Vera Rivera, Francisco Javier; González Colás, Antonio María; Ergin, Oguz (2006-12)
    Article
    Accés obert
    Parameter variations, which are increasing along with advances in process technologies, affect both timing and power. Variability must be considered at both the circuit and microarchitectural design levels to keep pace ...
  • Improving latency tolerance of multithreading through decoupling 

    Parcerisa Bundó, Joan Manuel; González Colás, Antonio María (2001-10)
    Article
    Accés obert
    The increasing hardware complexity of dynamically scheduled superscalar processors may compromise the scalability of this organization to make an efficient use of future increases in transistor budget. SMT processors, ...
  • Hypercube algorithms on mesh connected multicomputers 

    Díaz de Cerio Ripalda, Luis Manuel; Valero García, Miguel; González Colás, Antonio María (2002-12)
    Article
    Accés obert
    A new methodology named CALMANT (CC-cube Algorithms on Meshes and Tori) for mapping a type of algorithm that we call CC-cube algorithm onto multicomputers with hypercube, mesh, or torus interconnection topology is proposed. ...
  • A risk assessment framework for cloud computing 

    Djemame, Karim; Armstrong, Django; Guitart Fernández, Jordi; Macías Lloret, Mario (Institute of Electrical and Electronics Engineers (IEEE), 2016-07-01)
    Article
    Accés obert
    Cloud service providers offer access to their resources through formal service level agreements (SLA), and need well-balanced infrastructures so that they can maximise the quality of service (QoS) they offer and minimise ...
  • Flex-Grid/SDM backbone network design with inter-core XT-limited transmission reach 

    Perelló Muntan, Jordi; Gene Bernaus, Joan M.; Pagès Cruz, Albert; Lázaro Villa, José Antonio; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2016-08-01)
    Article
    Accés restringit per política de l'editorial
    Spatial division multiplexing (SDM) has been presented as a key solution to circumvent the nonlinear Shannon limit of standard single-core fibers. To implement SDM, multi-core fiber (MCF) technology becomes a top candidate ...
  • SURF-based mammalian species identification system 

    Otero Calviño, Beatriz; Rodríguez Luna, Eva; Ventura Queija, Jacint (2016-05-31)
    Article
    Accés restringit per política de l'editorial
    The development of tools for the automated identification of species will reduce the burden of routine identifications conducted by many biologists. The design of these tools is difficult because it depends on the proper ...
