  • 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 ...
  • Using the Marshall-Olkin extended Zipf distribution in graph generation 

    Duarte Lopez, Ariel; Prat Pérez, Arnau; Pérez Casany, Marta (Springer, 2015-12-18)
    Capítol de llibre
    Accés restringit per política de l'editorial
    Being able to generate large synthetic graphs resembling those found in the real world, is of high importance for the design of new graph algorithms and benchmarks. In this paper, we first compare several probability models ...
  • Computing size-independent matrix problems on systolic array processors 

    Navarro Guerrero, Juan José; Llaberia Griñó, José M.; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 1986)
    Text en actes de congrés
    Accés obert
    A methodology to transform dense to band matrices is presented in this paper. This transformation, is accomplished by triangular blocks partitioning, and allows the implementation of solutions to problems with any given ...
  • 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.
  • Overview on agent-based social modelling and the use of formal languages 

    Montañola Sales, Cristina; Cela Espín, José M.; Rubio Campillo, Xavier; Casanovas Garcia, Josep; Kaplan Marcusan, Adriana (IGI Global, 2013-07)
    Capítol de llibre
    Accés obert
    Transdisciplinary Models and Applications investigates a variety of programming languages used in validating and verifying models in order to assist in their eventual implementation. This book will explore different methods ...
  • Agent-based simulation of large population dynamics 

    Montañola Sales, Cristina; Casanovas Garcia, Josep; Cela Espín, José M.; Onggo, B.S.S.; Kaplan Marcusan, Adriana (2013)
    Comunicació de congrés
    Accés obert
    Agent-based modelling and simulation is a promising methodology that can be used in the study of population dynamics. One of the main obstacles hindering the use of agent-based simulation in practice is its scalability, ...
  • Parallel simulation of large population dynamics 

    Montañola Sales, Cristina; Casanovas Garcia, Josep; Cela Espín, José M.; Kaplan Marcusan, Adriana (2013)
    Comunicació de congrés
    Accés obert
    Agent-based modeling and simulation is a promising methodology that can be used in the study of population dynamics. We present the design and development of a simulation tool which provides basic support for modeling and ...
  • CellSim: a validated modular heterogeneous multiprocessor simulator 

    Cabarcas Jaramillo, Felipe; Rico Carro, Alejandro; Ródenas Picó, David; Martorell Bofill, Xavier; Ramírez Bellido, Alejandro; Ayguadé Parra, Eduard (Thomson Editores Spain, 2007)
    Text en actes de congrés
    Accés obert
    As the number of transistors on a chip continues increasing the power consumption has become the most important constraint in processors design. Therefore, to increase performance, computer architects have decided to use ...
  • 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 ...
