  • Predictable performance in SMT processors: synergy between the OS and SMTs 

    Cazorla, Francisco; Knijnenburg, Peter M.W.; Sakellariou, Rizos; Fernandez Prieto, Enrique; Ramírez Bellido, Alejandro; Valero Cortés, Mateo (2006-07)
    Article
    Accés obert
    Current operating systems (OS) perceive the different contexts of simultaneous multithreaded (SMT) processors as multiple independent processing units, although, in reality, threads executed in these units compete for the ...
  • Early 21st Century processors 

    Vajapeyam, Sriram; Valero Cortés, Mateo (2001-04)
    Article
    Accés obert
    The computer architecture arena faces exciting challenges as it attempts to meet the design goals and constraints that new markets, changing applications and fast-moving semiconductor technology impose.
  • Multicore resource management 

    Nesbit, Kyle J.; Smith, James E.; Moreto Planas, Miquel; Cazorla, Francisco; Ramírez Bellido, Alejandro; Valero Cortés, Mateo (2008-06)
    Article
    Accés obert
    Current resource management mechanisms and policies are inadequate for future multicore systems. Instead, a hardware/software interface based on the virtual private machine abstraction would allow software policies to ...
  • Better branch prediction through prophet/critic hybrids 

    Falcón Samper, Ayose Jesús; Stark, Jared; Ramírez Bellido, Alejandro; Lai, Konrad; Valero Cortés, Mateo (2005-01)
    Article
    Accés obert
    The prophet/critic hybrid conditional branch predictor has two component predictors. The prophet uses a branch's history to predict its direction. We call this prediction and the ones for branches following it the branch ...
  • Partitioning: an essential step in mapping algorithms into systolic array processors 

    Navarro Guerrero, Juan José; Llaberia Griñó, José M.; Valero Cortés, Mateo (1987-07)
    Article
    Accés obert
    The efficient solution of a large problem on a small systolic array requires good partitioning techniques to split the problem into subproblems that fit the array size.
  • Synchronized access to streams in multiprocessors 

    Peiron Guàrdia, Montse; Valero Cortés, Mateo; Ayguadé Parra, Eduard; Lang, Tomás (Institute of Electrical and Electronics Engineers (IEEE), 1993-10)
    Article
    Accés obert
    The synchronized and simultaneous access to several vectors that form a single stream occurs in SIMD vector multiprocessors as well as in MIMD superscalar multiprocessors with decoupled access. In this paper we propose a ...
  • Bandwidth of crossbar and multiple-bus connections for multiprocessors 

    Lang, Tomás; Valero Cortés, Mateo; Alegre de Miguel, Ignasi (1982-12)
    Article
    Accés obert
    In this paper we compare the effective bandwidth in a multiprocessor with shared memory using as interconnection networks the crossbar or the multiple-bus. We consider a system with N processors and N memory modules, in ...
  • La fortuna dels Commons: noves capacitats per als emprenedors socials 

    Franquesa Griso, David (2009-11-05)
    Article
    Accés obert
  • DaSH: a benchmark suite for hybrid dataflow and shared memory programming models 

    Gajinov, Vladimir; Stipic, Srdjan; Eric, Igor; Unsal, Osman Sabri; Ayguadé Parra, Eduard; Cristal Kestelman, Adrián (2015-06-01)
    Article
    Accés restringit per política de l'editorial
    The current trend in development of parallel programming models is to combine different well established models into a single programming, model in order to support efficient implementation of a wide range of real world ...
  • Advances in wireless community networks with the community-lab testbed 

    Navarro Moldes, Leandro; Baig Viñas, Roger; Barz, Christoph; Bonicioli, Joseph; Braem, Bart; Freitag, Fèlix; Vilalta i Balaguer, Ivan (2016-07)
    Article
    Accés obert
    Beyond traditional telecom providers, citizens and organizations pool their own resources and coordinate in order to build local network infrastructures to address the digital divide in many parts of the world. These ...
