      López, Victor; Criado Ledesma, Joel; Peñacoba Veigas, Raúl; Ferrer Ibañez, Roger; Teruel García, Xavier; Garcia Gasulla, Marta (Springer, 2021)
      Conference report
      Open Access
      In this paper, we introduce a design and implementation of the free agent threads for OpenMP. These threads increase the malleability of the OpenMP programming model, offering resource managers and runtime systems flexibility ...

      DMRG++ (Density Matrix Renormalization Group) és una aplicació de física de la matèria condensada orientada a HPC, originalment desenvolupada per l'Oak Ridge National Laboratory (ORNL). En aquest projecte es treballarà en ...
    • Performance and energy consumption of HPC workloads on a cluster based on Arm ThunderX2 CPU 

      Mantovani, Filippo; Garcia Gasulla, Marta; Gracia, Jose; Stafford, Esteban; Banchelli Gracia, Fabio; Josep Fabregó, Marc; Criado Ledesma, Joel; Nachtmann, Mathias (Elsevier, 2020-11)
      Open Access
      In this paper, we analyze the performance and energy consumption of an Arm-based high-performance computing (HPC) system developed within the European project Mont-Blanc 3. This system, called Dibona, has been integrated ...
