    Cadenelli, Nicola; Jun, Sang-Woo; Polo Bardés, Jorda; Wright, Andrew J.; Carrera Pérez, David; Mithal, Arvind (Frontiers Media SA, 2021-04)
    Article
    Open Access
    Analysis of a patient’s genomics data is the first step toward precision medicine. Such analyses are performed on expensive enterprise-class server machines because input data sets are large, and the intermediate data ...
  • Forecastability measures that describe the complexity of a site for deep learning wind predictions 

    Manero Font, Jaume; Béjar Alonso, Javier (2021-05-29)
    Article
    Open Access
    The application of deep learning to wind time series for multi-step prediction obtains good results at short horizons. The accuracy of a wind forecast is highly dependent on the specific structure of wind in the specific ...
  • The OpenMP API for high integrity systems: Moving responsibility from users to vendors 

    Klemm, Michael; Quiñones, Eduardo; Taft, Tucker; Ziegenbein, Dirk; Royuela Alcázar, Sara (Association for Computing Machinery, 2021)
    Article
    Open Access
    OpenMP is traditionally focused on boosting performance in HPC systems. However, other domains are showing an increasing interest in the use of OpenMP by virtue of key aspects introduced in recent versions of the specification: ...
  • Performance characterization of video analytics workloads in heterogeneous edge infrastructures 

    Rivas Barragan, Daniel; Guim Bernat, Francesc; Polo Bardés, Jorda; Carrera Pérez, David (Wiley (John Wiley & Sons), 2021-05-07)
    Article
    Open Access
    Powered by deep learning, video analytic applications process millions of camera feeds in real-time to extract meaningful information from their surroundings. And this number grows by the minute. To avoid saturating the ...
  • Specific heat effects in two-dimensional shock refractions 

    Martínez Ruiz, Daniel; Huete, Cesar; Martínez Ferrer, Pedro J.; Mira Martinez, Daniel (Springer, 2021)
    Article
    Restricted access - publisher's policy
    Compressible mixtures in supersonic flows are subject to significant temperature changes via shock waves and expansions, which affect several properties of the flow. Besides the widely studied variable transport effects ...
  • Efficient selective replication of critical code regions for SDC mitigation leveraging redundant multithreading 

    Arslan, Sanem; Unsal, Osman Sabri (Springer, 2021)
    Article
    Restricted access - publisher's policy
    Redundant multithreading (RMT) is an effective reliability solution that provides thread-level replication; however, it imposes additional overheads in terms of performance loss or energy consumption. Partial-RMT is an ...
  • A generic performance analysis technique applied to different CFD methods for HPC 

    Garcia Gasulla, Marta; Banchelli Gracia, Fabio; Peiró Conde, Kilian; Ramírez Gargallo, Guillem; Houzeaux, Guillaume; Hassan Saïdi, Ismaïl Ben; Tenaud, Christian; Spisso, Ivan; Mantovani, Filippo (Taylor & Francis, 2020-07-16)
    Article
    Open Access
    For complex engineering and scientific applications, Computational Fluid Dynamics (CFD) simulations require a huge amount of computational power. As such, it is of paramount importance to carefully assess the performance ...
  • The impact of non-additive genetic associations on age-related complex diseases 

    Guindo Martínez, Marta; Amela Milian, Ramon; Bonàs Guarch, Silvia; Puiggros Maldonado, Montserrat; Salvoro, Cecilia; Miguel Escalada, Irene; Sánchez Castaño, Friman; Ramón Cortés, Cristian; Badia Sala, Rosa Maria; Ejarque Artigas, Jorge; Mercader Bigas, Josep Maria; Torrents Rodas, David (2021-04-23)
    Article
    Open Access
    Genome-wide association studies (GWAS) are not fully comprehensive, as current strategies typically test only the additive model, exclude the X chromosome, and use only one reference panel for genotype imputation. We ...
  • Dynamic reconfiguration of noniterative scientific applications A case study with HPG aligner 

    Iserte, Sergio; Martínez Pérez, Héctor; Barrachina Mir, Sergio; Castillo Catalán, Maribel; Mayo, Rafael; Peña, Antonio (SAGE Publications, 2018)
    Article
    Open Access
    Several studies have proved the benefits of job malleability, that is, the capacity of an application to adapt its parallelism to a dynamically changing number of allocated processors. The most remarkable advantages of ...
  • Enabling homomorphically encrypted inference for large DNN models 

    Lloret Talavera, Guillermo; Jorda, Marc; Servat, Harald; Boemer, Fabian; Chauhan, Chetan; Tomishima, Shigeki; Shah, Nilesh N.; Peña, Antonio (Institute of Electrical and Electronics Engineers, 2021)
    Article
    Open Access
    The proliferation of machine learning services in the last few years has raised data privacy concerns. Homomorphic encryption (HE) enables inference using encrypted data but it incurs 100x-10,000x memory and runtime ...
  • Efficient bypass in mesh and torus NoCs
