    The simulation of the behavior of the Human Brain is one of the most important challenges in computing today. The main problem consists of finding efficient ways to manipulate and compute the huge volume of data that this ...
  • ReD: A reuse detector for content selection in exclusive shared last-level caches 

    Díaz, Javier; Monreal Arnal, Teresa; Ibáñez Marín, Pablo Enrique; Llaberia Griñó, José M.; Viñals Yúfera, Víctor (Elsevier, 2019-03)
    Article
    Accés restringit per política de l'editorial
    The reference stream reaching a chip multiprocessor Shared Last-Level Cache (SLLC) shows poor temporal locality, making conventional cache management policies inefficient. Few proposals address this problem for exclusive ...
  • A fault-tolerant last level cache for CMPs operating at ultra-low voltage 

    Ferrerón, Alexandra; Alastruey, Jesús; Suárez Gracía, Dario; Monreal Arnal, Teresa; Ibáñez Marín, Pablo Enrique; Viñals Yúfera, Víctor (Elsevier, 2019-03)
    Article
    Accés restringit per política de l'editorial
    Voltage scaling to values near the threshold voltage is a promising technique to hold off the many-core power wall. However, as voltage decreases, some SRAM cells are unable to operate reliably and show a behavior consistent ...
  • A resilient and distributed near real-time traffic forecasting application for Fog computing environments
