    Open Access
    All the supercomputers in the world exploit data-level parallelism (DLP), for example by using single instructions to operate over several data elements. Improving vector processing is therefore key for exascale computing. ...
  • Size & shape matters: The need of HPC benchmarks of high resolution image training for deep learning 

    Parés Pont, Ferran; Megias Montsesinos, Pedro; García Gasulla, Dario; Garcia Gasulla, Marta; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (2021-03)
    Article
    Open Access
    One of the purposes of HPC benchmarks is to identify limitations and bottlenecks in hardware. This functionality is particularly influential when assessing performance on emerging tasks, the nature and requirements of which ...
  • Workload-aware placement strategies to leverage disaggregated resources in the datacenter 

    Call Barreiro, Aaron; Polo Bardés, Jorda; Carrera Pérez, David (2021-07)
    Article
    Open Access
    Disaggregation of resources is a datacenter strategy that aims to decouple the physical location of resources from the place where they are accessed, as opposed to physically attached devices connected to the Peripheral ...

    Database management systems have become an indispensable tool for industry, government, and academia, and form a significant component of modern datacenters. They can be used in a multitude of scenarios, including online ...
  • OmpSs@FPGA framework for high performance FPGA computing 

    Haro Ruiz, Juan Miguel de; Bosch Pons, Jaume; Filgueras Izquierdo, Antonio; Vidal, Miquel; Jiménez González, Daniel; Álvarez Martínez, Carlos; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2021-06-02)
    Article
    Open Access
    This paper presents the new features of the OmpSs@FPGA framework. OmpSs is a data-flow programming model that supports task nesting and dependencies to target asynchronous parallelism and heterogeneity. OmpSs@FPGA is the ...
  • Enabling genomics pipelines in commodity personal computers with flash storage 

    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 ...
  • 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 ...
  • Near-optimal replacement policies for shared caches in multicore processors 

    Díaz Maag, Javier; Ibáñez Marín, Pablo; Monreal Arnal, Teresa; Viñals Yúfera, Victor; Llaberia Griñó, José M. (2021-03-29)
    Article
    Restricted access - publisher's policy
    An optimal replacement policy that minimizes the miss rate in a private cache was proposed several decades ago. It requires knowing the future access sequence the cache will receive. There is no equivalent for shared caches ...
  • Smoothed particle hydrodynamics simulations of water flow in a 90° pipe bend 

    Sigalotti, Leonardo Di G.; Alvarado Rodríguez, Carlos E.; Klapp, Jaime; Cela Espín, José M. (2021-04-14)
    Article
    Open Access
    The flow through pipe bends and elbows occurs in a wide range of applications. While many experimental data are available for such flows in the literature, their numerical simulation is less abundant. Here, we present ...
  • 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 ...
