  • TCP Proactive Congestion Control for East–West Trffic: the Marking Threshold 

    Fischer e Silva, Renan; Carpenter, Paul M. (Elsevier, 2019-03)
    Working paper
    Restricted access - publisher's policy
    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 ...
  • TensorFlow on state-of-the-art HPC clusters: a machine learning use case 

    Ramirez-Gargallo, Guillem; Garcia-Gasulla, Marta; Mantovani, Filippo (2019)
    Conference lecture
    Open Access
    The recent rapid growth of the data-flow programming paradigm enabled the development of specific architectures, e.g., for machine learning. The most known example is the Tensor Processing Unit (TPU) by Google. Standard ...
  • Design Space Exploration of Next-Generation HPC Machines 

    Gómez, Constantino; Martínez, Francesc; Armejach, Adrià; Moretó, Miquel; Mantovani, Filippo; Casas, Marc (2019)
    External research report
    Open Access
    The landscape of High Performance Computing (HPC) system architectures keeps expanding with new technologies and increased complexity. With the goal of improving the efficiency of next-generation large HPC systems, ...
  • Filling the gap between education and industry: evidence-based methods for introducing undergraduate students to HPC 

    Mantovani, Filippo; Banchelli, Fabio (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference lecture
    Open Access
    Educational institutions provide in most cases basic theoretical background covering several computational science topics, however High Performance Computing (HPC) and Parallel and Distributed Computing (PDC) markets require ...
  • The HPCG benchmark: analysis, shared memory preliminary improvements and evaluation on an Arm-based platform 

    Ruiz, Daniel; Mantovani, Filippo; Casas, Marc; Labarta, Jesus; Spiga, Filippo (2018)
    External research report
    Open Access
    The High-Performance Conjugate Gradient (HPCG) benchmark complements the LINPACK benchmark in the performance evaluation coverage of large High-Performance Computing (HPC) systems. Due to its lower arithmetic intensity and ...
  • Advanced Performance Analysis of HPC Workloads on Cavium ThunderX 

    Calore, Enrico; Mantovani, Filippo; Ruiz, Daniel (IEEE, 2018)
    Conference lecture
    Open Access
    The interest towards Arm based platforms as HPC solutions increased significantly during the last 5 years. In this paper we show that, in contrast to the early days of pioneer tests, several application performance analysis ...
