  • 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 ...
  • 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)

    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 ...
  • Virtual registers 

    González Colás, Antonio María; Valero Cortés, Mateo; González González, José; Monreal Arnal, Teresa (Institute of Electrical and Electronics Engineers (IEEE), 1997)
    Text en actes de congrés
    Accés obert
    The number of physical registers is one of the critical issues of current superscalar out-of-order processors. Conventional architectures allocate, in the decoding stage, a new storage location (e.g. a physical register) ...
  • Distributed training strategies for a computer vision deep learning algorithm on a distributed GPU cluster 

    Campos Camunez, Victor; Sastre, Francesc; Yagües, Maurici; Bellver, Míriam; Giró Nieto, Xavier; Torres Viñals, Jordi (Elsevier, 2017)
    Comunicació de congrés
    Accés obert
    Deep learning algorithms base their success on building high learning capacity models with millions of parameters that are tuned in a data-driven fashion. These models are trained by processing millions of examples, so ...
  • Envisioning cloud of energy 

    Sharifi, Leila; Freitag, Fèlix; Veiga, Luis (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Energy and Information and Communication Technology (ICT), as two driving forces of the contemporary life, are reshaping themselves based on ubiquitous society architecture to improve their service quality. Within the ...
  • From plasma to beefarm: Design experience of an FPGA-based multicore prototype 

    Sonmez, Nehir; Arcas Abella, Oriol; Sayilar, Gokhan; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Hur, Ibrahim; Singh, Satnam; Valero Cortés, Mateo (Springer, 2011)
    Text en actes de congrés
    Accés obert
    In this paper, we take a MIPS-based open-source uniprocessor soft core, Plasma, and extend it to obtain the Beefarm infrastructure for FPGA-based multiprocessor emulation, a popular research topic of the last few years ...
  • ARTA: An economic middleware to exchange pervasive energy and computing resources 

    Sharifi, Leila; Freitag, Fèlix; Veiga, Luis (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés obert
    Studies reveal that an integrated system of smart grid and cloud computing ecosystems can better attain the energy efficiency objectives, considering all the aspects. To facilitate the integration, in this paper, we introduce ...
  • Securing combined Fog-to-Cloud system through SDN approach 

    Kahvazadeh, Sarang; Barbosa Carlos de Souza, Vitor; Masip Bruin, Xavier; Marín Tordera, Eva; García Almiñana, Jordi; Diaz, Rodrigo (Association for Computing Machinery (ACM), 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Future IoT services execution may benefit from combining resources at cloud and at the edge. To that end, new architectures should be proposed to handle IoT services in a coordinated way at either the edge of the network, ...
