    • 3D Viscoelastic Anisotropic Seismic Modeling with High-Order Mimetic Finite Differences 

      Ferrer, Miguel; de la Puente, Josep; Farrés, Albert; Castillo, José E. (Springer, 2015)
      Part of book or chapter of book
      Open Access
      We present a scheme to solve three-dimensional viscoelastic anisotropic wave propagation on structured staggered grids. The scheme uses a fully-staggered grid (FSG) or Lebedev grid (Lebedev, J Sov Comput Math Math Phys ...
    • Acceleration strategies for elastic full waveform inversion workflows in 2D and 3D 

      Kormann, Jean; Rodríguez, Juan E.; Ferrer, Miguel; Farrés, Albert; Gutiérrez, Natalia; de la Puente, Josep; Hanzich, Mauricio; Cela, José M. (Springer International Publishing, 2017-02-01)
      Open Access
      Full waveform inversion (FWI) is one of the most challenging procedures to obtain quantitative information of the subsurface. For elastic inversions, when both compressional and shear velocities have to be inverted, the ...
    • Optimizing an Elastic Wave Propagation by Means of a Roofline-Based Strategy on Xeon Processors 

      Hanzich, Mauricio; Farrés, Albert; Rubio, Felix (European Association of Geoscientists and Engineers, 2015-07)
      Conference report
      Open Access
      Acoustic wave propagation has been the preferred engine for geophysical exploration applications for the last few years due to the large cost involved in using better approximations, especially for 3D full-wave field ...
    • Strategies to Improve the Performance of a Geophysics Model for Different Manycore Systems 

      Serpa, Matheus S.; Cruz, Eduardo H.M.; Diener, Matthias; Krause, Arthur M.; Navaux, Philippe O.A.; Farrés, Albert; Rosas, Claudia; Hanzich, Mauricio; Panetta, Jairo (IEEE, 2017-11-16)
      Conference lecture
      Open Access
      Many software mechanisms for geophysics exploration in Oil & Gas industries are based on wave propagation simulation. To perform such simulations, state-of-art HPC architectures are employed, generating results faster and ...
