  • Alya: Computational Solid Mechanics for Supercomputers 

    Casoni Rero, Eva; Jérusalem, Antoine; Samaniego, Cristóbal; Eguzkitza, Beatriz; Lafortune, Pierre; Tjahjanto, Denny; Sáez, Xavier; Houzeaux, Guillaume; Vázquez, Mariano (Springer, 2014-08-13)
    Article
    Open Access
    While solid mechanics codes are now conventional tools both in industry and research, the increasingly more exigent requirements of both sectors are fuelling the need for more computational power and more advanced algorithms. ...

  • First experience with particle-in-cell plasma physics code on ARM-based HPC systems 

    Sáez, Xavier; Soba, Alejandro; Sánchez, Edilberto; Mantsinen, Mervi; Mateo, Sergio; Cela, José M.; Castejón, Francisco (IOP Publishing, 2015-09-28)
    Article
    Open Access
    In this work, we will explore the feasibility of porting a Particle-in-cell code (EUTERPE) to an ARM multi-core platform from the Mont-Blanc project. The used prototype is based on a system-on-chip Samsung Exynos 5 with ...
  • Nonlinear electromagnetic stabilization of ITG microturbulence by ICRF-driven fast ions in ASDEX Upgrade 

    de Oliveira, F.N.; Doerk, H.; Mantsinen, Mervi J.; Angioni, C.; Bilato, R.; Bobkov, V.; Dunne, M.; Gallart, D.; Gutiérrez-Milla, A.; Mantica, P.; Odstrcil, T.; Tardini, G.; Sáez, Xavier; ASDEX Upgrade Team; EUROfusion MST1 Team (2016-10)
    Conference lecture
    Open Access
    Electromagnetic waves in the range of Ion Cyclotron Resonance Frequencies (ICRF) have many applications in fusion devices. While their use for external heating of magnetically confined fusion plasmas is well established, ...
  • Plasma physics code contribution to the Mont-Blanc project 

    Sáez, Xavier; Soba, Alejandro; Mantsinen, Mervi (Barcelona Supercomputing Center, 2015-05-05)
    Conference report
    Open Access
    This work develops strategies for adapting a particle-in-cell code to heterogeneous computer architectures and, in particular, to an ARM-based prototype of the Mont-Blanc project using OmpSs programming model and the ...

(American Nuclear Society, 2018-02-21)
    Article
    Open Access
    Integrated modeling (IM) of present experiments and future tokamak reactors requires the provision of computational resources and numerical tools capable of simulating multiscale spatial phenomena as well as fast transient ...
  • Simulations of combined ICRF and NBI heating for high fusion performance in JET 

    Gallart, Daniel; Mantsinen, Mervi; Garzotti, Luca; Bilato, Roberto; Challis, Clive; Garcia, Jerónimo; Gutierrez-Milla, Albert; Johnson, Thomas; Lerche, Ernesto; Sáez, Xavier; van Eester, Dirk (2016-07-08)
    Conference lecture
    Open Access
    We report on simulations aimed at optimizing external heating using neutral beam injection (NBI) and radiofrequency waves in the ion cyclotron range of frequencies (ICRF) for high fusion yield in the JET tokamak. In this ...
