    D'Amico, Marco; Garcia Gasulla, Marta; López, Victor; Jokanovic, Ana; Sirvent, Raül; Corbalán González, Julita (Association for Computing Machinery (ACM), 2018-08-13)
    Conference lecture
    Open Access
    In the design of future HPC systems, research in resource management is showing an increasing interest in a more dynamic control of the available resources. It has been proven that enabling the jobs to change the number ...
  • MPI+X: task-based parallelization and dynamic load balance of finite element assembly 

    Garcia-Gasulla, Marta; Houzeaux, Guillaume; Ferrer, Roger; Artigues, Antoni; López, Victor; Labarta, Jesús; Vázquez, Mariano (Taylor & Francis, 2018)
    Open Access
    The main computing tasks of a finite element code(FE) for solving partial differential equations (PDE's) are the algebraic system assembly and the iterative solver. This work focuses on the first task, in the context of ...
  • Performance analysis and optimization of the FFTXlib on the Intel knights landing architecture 

    Wagner, Michael; López, Victor; Morillo, Julian; Cavazzoni, Carlo; Affinito, Fabio; Gimenez, Judit; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Open Access
    In this paper, we address the decreasing performance of the FFTXlib, the Fast Fourier Transformation (FFT) kernel of Quantum ESPRESSO, when scaling to a full KNL node. An increased performance in the FFTXlib will likewise ...
