    • Evaluating directive-based programming models on Wave Propagation Kernels 

      Rodriguez, Samuel; Farré, Pau; Rosas, Claudia; Hanzich, Mauricio (EAGE, 2017-06-12)
      Conference lecture
      Open Access
      HPC systems have become mandatory to tackle the ever-increasing challenges imposed by new exploration areas around the world. The requirement for more HPC resources depends on the complexity of the area under exploration, ...

    • Methodology to predict scalability of parallel applications 

      Rosas, Claudia; Giménez Lucas, Judit; Labarta Mancho, Jesús José (Barcelona Supercomputing Center, 2015-05-05)
      Conference report
      Open Access
      In the road to exascale computing, the inference of expected performance of parallel applications results in a complex task. Performance analysts need to identify the behavior of the applications and to extrapolate it to ...

    • Optimization strategies for geophysics models on manycore systems 

      Serpa, Matheus S.; Cruz, Eduardo HM; Diener, Matthias; Krause, Arthur M.; Navaux, Philippe; Panetta, Jairo; Farrés Coma, Albert; Rosas, Claudia; Hanzich, Mauricio (2019-01-17)
      Article
      Open Access
      Many software mechanisms for geophysics exploration in oil and gas industries are based on wave propagation simulation. To perform such simulations, state-of-the-art high-performance computing architectures are employed, ...

    • Optimizing Fully Anisotropic Elastic Propagation on 2nd Generation Intel Xeon Phi Processors 

      Farres, Albert; Duran, A.; Rosas, Claudia; Hanzich, Mauricio; Yount, C.; Fernandez, S. (2017-06-12)
      Conference lecture
      Open Access
      This work shows several optimization strategies evaluated and applied to an elastic wave propagation engine, based on a Fully Staggered Grid, running on the latest Intel Xeon Phi processors, the second generation of the ...

    • Performance optimization of fully anisotropic elastic wave propagation on 2nd Generation Intel R PhiTM processors 

      Farres, Albert; Rosas, Claudia; Hanzich, Mauricio; Duran, Alejandro; Yount, Charles (Barcelona Supercomputing Center, 2019-05-07)
