    Conference report
    Open Access
    Cycle accurate DRAM simulations have been the dominating architecture simulation model for DRAM for a long time. Although accurate, its poor simulation speed has not improved for years while a lot of other architecture ...
  • Cross-modal neural sign language translation 

    Cardoso Duarte, Amanda (Association for Computing Machinery (ACM), 2019)
    Conference report
    Open Access
    Sign Language is the primary means of communication for the majority of the Deaf and hard-of-hearing communities. Current computational approaches in this general research area have focused specifically on sign language ...
  • Analyzing the efficiency of hybrid codes 

    Giménez Lucas, Judit; Mercadal, Estanislao; Llort, German; Méndez, Sandra (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    Hybrid parallelization may be the only path for most codes to use HPC systems on a very large scale. Even within a small scale, with an increasing number of cores per node, combining MPI with some shared memory thread-based ...
  • Software-only triple diverse redundancy on GPUs for autonomous driving platforms 

    Alcaide Portet, Sergi; Kosmidis, Leonidas; Hernández Luz, Carles; Abella Ferrer, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    Autonomous driving (AD) imposes the need for safe computations in high-performance computing (HPC) components such as GPUs, thus with capabilities to detect and recover from errors since a safe state may not exist anymore. ...
  • An optimized predication execution for SIMD extensions 

    Barredo Ferreira, Adrián; Cebrián González, Juan Manuel; Moreto Planas, Miquel; Casas Guix, Marc; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    Vector processing is a widely used technique to improve performance and energy efficiency in modern processors. Most of them rely on predication to support divergence control. However, performance and energy consumption ...
  • Checkpoint restart support for heterogeneous HPC applications 

    Parasyris, Konstantinos; Keller, Kai Rasmus; Bautista Gomez, Leonardo Arturo; Unsal, Osman Sabri (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    As we approach the era of exa-scale computing, fault tolerance is of growing importance. The increasing number of cores as well as the increased complexity of modern heterogenous systems result in substantial decrease of ...
  • Twig: Multi-agent task management for colocated latency-critical cloud services 

    Nishtala, Rajiv; Petrucci, Vinicius; Carpenter, Paul; Sjalander, Magnus (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference lecture
    Open Access
    Many of the important services running on data centres are latency-critical, time-varying, and demand strict usersatisfaction. Stringent tail-latency targets for colocated services and increasing system complexity make it ...
  • Experiences on the characterization of parallel applications in embedded systems with Extrae/Paraver 

    Munera, Adrian; Royuela Alcázar, Sara; Llort Sánchez, Germán; Mercadal, Estanislao; Wartel, Franck; Quiñones, Eduardo (Association for Computing Machinery (ACM), 2020-08)
    Conference lecture
    Open Access
    Cutting-edge functionalities in embedded systems require the use of parallel architectures to meet their performance requirements. This imposes the introduction of a new layer in the software stacks of embedded systems: ...
  • Tracing Hardware Monitors in the GR712RC Multicore Platform: Challenges and Lessons Learnt from a Space Case Study 

    Palomo, Xavier; Girbal, Sylvain; Abella Ferrer, Jaume; Rioux, Laurent; Fernández, Mikel; Mezzetti, Enrico; Cazorla Almeida, Francisco Javier (Schloss Dagstuhl – Leibniz-Zentrum für Informatik, 2020)
    Conference lecture
    Open Access
    The demand for increased computing performance is driving industry in critical-embedded systems (CES) domains, e.g. space, towards the use of multicores processors. Multicores, however, pose several challenges that must ...
