    • 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. ...

    • Development of HPC multiphysics framework for HTS magnets in fusion 

      Lorenzo, José; Castillo-Reyes, Octavio; Granados García, Javier A.J.; Mantsinen, Mervi; Sáez, Xavier; Soba, Alejandro (Barcelona Supercomputing Center, 2019-05-07)
      Conference report

    • 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 ...

    • Recent EUROfusion Achievements in Support of Computationally Demanding Multiscale Fusion Physics Simulations and Integrated Modeling 

      Voitsekhovitch, I.; Hatzky, R.; Coster, D.; Imbeaux, F.; McDonald, D.C.; Fehér, T.B.; Kang, K.S.; Leggate, H.; Martone, M.; Mochalskyy, S.; Sáez, Xavier; Ribeiro, T.; Tran, T.-M-; Gutierrez-Milla, A.; Aniel, T.; Figat, D.; Fleury, L.; Hoenen, O.; Hollocombe, J.; Kaljun, D.; Manduchi, G.; Owsiak, M.; Pais, V.; Palak, B.; Plociennik, M.; Signoret, J.; Vouland, C.; Yadykin, D.; Robin, F.; Iannone, F.; Bracco, G.; David, J.; Maslennikov, A.; Noé, J.; Rossi, E.; Kamendje, R.; Heuraux, S.; Hölzl, M.; Pinches, S.D.; da Silva, F.; Tskhakaya, D. (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 ...
