    Power consumption and high compute density are the key factors to be considered when building a compute node for the upcoming Exascale revolution. Current architectural design and manufacturing technologies are not able ...
  • High Throughput and Low Latency on Hadoop Clusters Using Explicit Congestion Notification: The Untold Truth 

    Fischer e Silva, Renan; Carpenter, Paul M. (IEEE, 2017-09-26)
    Comunicació de congrés
    Accés obert
    Various extensions of TCP/IP have been proposed to reduce network latency; examples include Explicit Congestion Notification (ECN), Data Center TCP (DCTCP) and several proposals for Active Queue Management (AQM). Combining ...
  • Boosting Guaranteed Performance in Wormhole NoCs with Probabilistic Timing Analysis 

    Slijepcevic, Mladen; Hernandez, Carles; Abella, Jaume; Cazorla, Francisco J. (IEEE, 2017-09-28)
    Comunicació de congrés
    Accés obert
    Wormhole-based NoCs (wNoCs) are widely accepted in high-performance domains as the most appropriate solution to interconnect an increasing number of cores in the chip. However, wNoCs suitability in the context of critical ...
  • Predicting access to persistent objects through static code analysis 

    Touma, Rizkallah; Queralt Calafat, Anna; Cortés, Toni; Pérez Hernandez, María S. (Springer, 2017)
    Text en actes de congrés
    Accés obert
    In this paper, we present a fully-automatic, high-accuracy approach to predict access to persistent objects through static code analysis of object-oriented applications. The most widely-used previous technique uses a simple ...
  • Efficient data sharing on heterogeneous systems 

    García-Flores, Víctor; Ayguadé Parra, Eduard; Peña, Antonio J. (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    General-purpose computing on GPUs has become more accessible due to features such as shared virtual memory and demand paging. Unfortunately it comes at a price, and that is performance. Automatic memory management is ...
  • Modelling bus contention during system early design stages 

    Trilla, David; Hernandez, Carles; Abella, Jaume; Cazorla, Francisco J. (IEEE, 2017-07-31)
    Comunicació de congrés
    Accés obert
    Reliably upperbounding contention in multicore shared resources is of prominent importance in the early design phases of critical real-time systems to properly allocate time budgets to applications. However, during early ...
  • A directive-based approach to perform persistent checkpoint/restart 

    Maroñas, Marcos; Mateo, Sergi; Beltran Querol, Vicenç; Ayguadé Parra, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Exascale platforms require support for resilience capabilities due to increasing numbers of components and associated error rates. In this paper, we present a new directive-based approach to perform application-level ...
  • Efficient Scalable Computing through Flexible Applications and Adaptive Workloads 

    Iserte, Sergio; Mayo, Rafael; Quintana-Ortí, Enrique S.; Beltran, Vicenç; Peña, Antonio J. (IEEE, 2017-09-07)
    Comunicació de congrés
    Accés obert
    In this paper we introduce a methodology for dynamic job reconfiguration driven by the programming model runtime in collaboration with the global resource manager. We improve the system throughput by exploiting malleability ...
  • On uses of extreme value theory fit for industrial-quality WCET analysis 

    Milutinovic, Suzana; Mezzetti, Enrico; Abella, Jaume; Vardanega, Tullio; Cazorla, Francisco J. (IEEE, 2017-07-31)
    Comunicació de congrés
    Accés obert
    Over the last few years, considerable interest has arisen in measurement-based probabilistic timing analysis. The term MBPTA has been used to indistinctly refer to a variety of different applications of Extreme Value Theory ...
  • GLTO: On the Adequacy of Lightweight Thread Approaches for OpenMP Implementations 

    Castelló, Adrián; Mayo, Rafael; Quintana-Ortí, Enrique S.; Seo, Sangmin; Balaji, Pavan; Peña, Antonio J. (IEEE, 2017-09-07)
    Comunicació de congrés
    Accés obert
    OpenMP is the de facto standard application programming interface (API) for on-node parallelism. The most popular OpenMP runtimes rely on POSIX threads (pthreads) implementations that offer an excellent performance for ...
