  • Gestión de contenidos en caches operando a bajo voltaje 

    Ferrerón, Alexandra; Alastruey, Jesús; Suárez Gracía, Dario; Monreal Arnal, Teresa; Ibáñez Marín, Pablo Enrique; Viñals Yúfera, Víctor (2016)
    Conference report
    Open Access
    La eficiencia energética de las caches en chip puede mejorarse reduciendo su voltaje de alimentación (Vdd ). Sin embargo, este escalado de Vdd está limitado a una tensión Vddmin por debajo de la cual algunas celdas SRAM ...
  • Selección de contenidos basada en reuso para caches compartidas en exclusión 

    Díaz Maag, Javier; Monreal Arnal, Teresa; Viñals Yúfera, Víctor; Ibáñez Marín, Pablo Enrique; Llaberia Griño, José María (2015)
    Conference report
    Open Access
    Publicaciones previas revelan que el flujo de referencias que llega a la cache compartida (SLLC) de un chip multiprocesador muestra poca localidad temporal. Sin embargo, muestra localidad de reuso, es decir, los bloques ...
  • A comparison of cache hierarchies for SMT processors 

    Suárez Gracía, Dario; Monreal Arnal, Teresa; Viñals Yúfera, Víctor (Universidad de La Laguna. Servicio de Publicaciones, 2011)
    Conference report
    Open Access
    In the multithread and multicore era, programs are forced to share part of the processor structures. On one hand, the state of the art in multithreading describes how efficiently manage and distribute inner resources such ...
  • An adaptive controller to save dynamic energy in LP-NUCA 

    Suárez Gracía, Dario; Monreal Arnal, Teresa; Viñals Yúfera, Víctor (Universidad de La Laguna. Servicio de Publicaciones, 2011)
    Conference report
    Open Access
    Portable devices often demand powerful processors to run computing intensive applications, such as video playing or gaming, and ultra low en-ergy consumption to extend device uptime. Such con-flicting requirements are hard ...
  • Oblivious routing schemes in extended generalized fat tree networks 

    Rodríguez Herrera, Germán; Minkenberg, Cyriel; Beivide Palacio, Ramon; Luijten, Ronald P.; Labarta Mancho, Jesús José; Valero Cortés, Mateo (IEEE Computational Intelligence Society, 2009)
    Conference report
    Open Access
    A family of oblivious routing schemes for fat trees and their slimmed versions is presented in this work. First, two popular oblivious routing algorithms, which we refer to as S-mod-k and D-mod-k, are analyzed in detail. ...
  • Selección del tamaño del banco de registros y de la política de asignación de recursos en procesadores SMT 

    Alastruey, Jesús; Monreal Arnal, Teresa; Cazorla Almeida, Francisco Javier; Viñals Yúfera, Víctor; Valero Cortés, Mateo (Thomson Editores Spain, 2007)
    Conference report
    Open Access
    Este trabajo estudia el impacto del tamaño del banco de registros físico (BRF) en el rendimiento de procesadores Simultaneous Multithreading (SMT). Como es bien conocido, el BRF es un componente crítico en este tipo de ...
  • MeRLiN: Exploiting dynamic instruction behavior for fast and accurate microarchitecture level reliability assessment 

    Kaliorakis, Manolis; Gizopoulos, Dimitris; Canal Corretger, Ramon; González Colás, Antonio María (Association for Computing Machinery (ACM), 2017)
    Conference report
    Open Access
    Early reliability assessment of hardware structures using microarchitecture level simulators can effectively guide major error protection decisions in microprocessor design. Statistical fault injection on microarchitectural ...
  • HW/SW co-designed processors: Challenges, design choices and a simulation infrastructure for evaluation 

    Kumar, Rakesh; Cano, José; Brankovic, Aleksandar; Pavlou, Demos; Stavrou, Kyriakos; Gibert Codina, Enric; Martínez, Alejandro; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Open Access
    Improving single thread performance is a key challenge in modern microprocessors especially because the traditional approach of increasing clock frequency and deep pipelining cannot be pushed further due to power constraints. ...
  • Removing checks in dynamically typed languages through efficient profiling 

    Dot, Gem; Martinez, Alejandro; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Open Access
    Dynamically typed languages increase programmer's productivity at the expense of some runtime overheads to manage the types of variables, since they are not declared at compile time and can change at runtime. One of the ...
  • Suitability of FinFET introduction into eDRAM cells for operate at sub-threshold level 

    Amat, Esteve; Calomarde Palomino, Antonio; Canal Corretger, Ramon; Rubio Sola, Jose Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference lecture
    Restricted access - publisher's policy
    This paper explores the feasibility, in terms of performance and reliability, of gain-cell embedded DRAM (eDRAM) to be operative at sub-threshold range, when they are implemented with 10 nm FinFET devices. The use of ...
  • ReD: A policy based on reuse detection for demanding block selection in last-level Caches 

    Díaz Maag, Javier; Ibáñez Marín, Pablo Enrique; Monreal Arnal, Teresa; Viñals Yúfera, Víctor; Llaberia Griñó, José M. (2017)
    Conference report
    Open Access
    In this paper, we propose a new block selection policy for Last-Level Caches (LLCs) that decides, based on Reuse Detection, whether a block coming from main memory is inserted, or not, in the LLC. The proposed policy, ...
  • Fluid communities: a competitive, scalable and diverse community detection algorithm 

    Pares, Ferran; García Gasulla, Darío; Vilalta, Armand; Moreno, Jonatan; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Cortés, Ulises; Suzumura, Toyotaro (Springer, 2017)
    Conference report
    Restricted access - publisher's policy
    We introduce a community detection algorithm (Fluid Communities) based on the idea of fluids interacting in an environment, expanding and contracting as a result of that interaction. Fluid Communities is based on the ...
