    • 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 ...

    • Asymmetric HMMs for online ball-bearing health assessments 

      Puerto Santana, Carlos; Bielza Lozoya, Concha; Díaz Rozo, Javier; Ramírez Gargallo, Guillem; Mantovani, Filippo; Virumbrales, Gaizka; Labarta Mancho, Jesús José; Larrañaga Mugica, Pedro (Institute of Electrical and Electronics Engineers (IEEE), 2022-10-15)
      Article
      Open Access
      The degradation of critical components inside large industrial assets, such as ball-bearings, has a negative impact on production facilities, reducing the availability of assets due to an unexpectedly high failure rate. ...

    • Cluster of emerging technology: evaluation of a production HPC system based on A64FX 

      Banchelli Gracia, Fabio; Peiró Conde, Kilian; Ramírez Gargallo, Guillem; Vinyals Ylla-Català, Joan; Vicente Dorca, David; Garcia Gasulla, Marta; Mantovani, Filippo (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      Clusters of emerging technologies are appearing with more and more frequency in HPC. After years of skepticism, data-centers are adopting them as production systems thanks to several geopolitical and technological factors. ...
