      The fluid-structure interaction (FSI) problem has received great attention in the last few years, mainly because it is present in many physical systems, industrial applications, and almost every biological system. In the ...
    • MPI+X: task-based parallelisation and dynamic load balance of finite element assembly 

      Garcia, Marta; Houzeaux, Guillaume; Ferrer, Roger; Artigues, Antoni; López, Victor; Labarta Mancho, Jesús José; Vázquez, Mariano (Taylor & Francis, 2019-05)
      Article
      Open Access
      The main computing phases of numerical methods for solving partial differential equations are the algebraic system assembly and the iterative solver. This work focuses on the first task, in the context of a hybrid MPI+X ...

      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 ...
    • Parallel Mesh Partitioning in Alya 

      Artigues, Antoni; Houzeaux, Guillaume (2015)
      External research report
      Open Access
      The Alya System is the BSC simulation code for multi-physics problems [1]. It is based on a Variational Multiscale Finite Element Method for unstructured meshes. Work distribution is achieved by partitioning the original ...
    • ParaView + Alya + D8tree: Integrating high performance computing and high performance data analytics 

      Artigues, Antoni; Cugnasco, Cesare; Becerra Fontal, Yolanda; Cucchietti, Fernando; Houzeaux, Guillaume; Vázquez, Mariano; Torres Viñals, Jordi; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Elsevier, 2017)
      Article
      Open Access
      Large scale time-dependent particle simulations can generate massive amounts of data, making it so that storing the results is often the slowest phase and the primary time bottleneck of the simulation. Furthermore, analysing ...
    • Scientific Big Data Visualization: a Coupled Tools Approach 

      Artigues, Antoni; Cucchietti, Fernando M.; Tripiana, Carlos; Vicente, David; Calmet, Hadrien; Marín, Guillermo; Houzeaux, Guillaume; Vázquez, Mariano (South Ural State University (Chelyabinsk, Russia), 2015-02)
      Article
      Open Access
      We designed and implemented a parallel visualisation system for the analysis of large scale time-dependent particle type data. The particular challenge we address is how to analyse a high performance computation style ...
