    • Acceleration of the Geostatistical Software Library (GSLIB) by code optimization and hybrid parallel programming 

      Peredo Andrade, Oscar Francisco; Ortiz, Julián; Herrero Zaragoza, José Ramón (2015-12-01)
      Article
      Accés obert
      The Geostatistical Software Library (GSLIB) has been used in the geostatistical community for more than thirty years. It was designed as a bundle of sequential Fortran codes, and today it is still in use by many practitioners ...

    • Algorithm 942: Semi-Stencil 

      de la Cruz, Raúl; Araya-Polo, Mauricio (ACM Digital Library, 2014-04-01)
      Article
      Accés obert
      Finite Difference (FD) is a widely used method to solve Partial Differential Equations (PDE). PDEs are the core of many simulations in different scientific fields, such as geophysics, astrophysics, etc. The typical FD ...

    • Ecosystem Simulator - Optimising Performance 

      Galve Millán, Pablo (Universitat Politècnica de Catalunya, 2022-07-14)
      Treball Final de Grau
      Accés obert
      The goal of this end of degree project is to develop an ecosystem simulator that can be used to learn about how ecosystems work in an easy, visual and fun way. Studying any discipline is tough, therefore this project ...

    • Efficient implementation of Galerkin meshfree methods for large-scale problems with an emphasis on maximum entropy approximants 

      Peco, Christian; Milian, Daniel; Rosolen, Adrian Martin; Arroyo Balaguer, Marino (2015-04-01)
      Article
      Accés obert
      In Galerkin meshfree methods, because of a denser and unstructured connectivity, the creation and assembly of sparse matrices is expensive. Additionally, the cost of computing basis functions can be significant in problems ...

    • Enlarging instruction streams 

      Santana Jaria, Oliverio J.; Ramírez Bellido, Alejandro; Valero Cortés, Mateo (2007-10)
      Article
      Accés obert
      The stream fetch engine is a high-performance fetch architecture based on the concept of an instruction stream. We call a sequence of instructions from the target of a taken branch to the next taken branch, potentially ...

    • Frost formation: optimizing solutions under a finite volume approach 

      Bartrons Casademont, Eduard; Pérez Segarra, Carlos David; Oliet Casasayas, Carles (Institute of Physics (IOP), 2016)
      Text en actes de congrés
      Accés obert
      A three-dimensional transient formulation of the frost formation process is developed by means of a finite volume approach. Emphasis is put on the frost surface boundary condition as well as the wide range of empirical ...

    • Tuning and hybrid parallelization of a genetic-based multi-point statistics simulation code 

      Peredo, Oscar; Ortiz, Julián M.; Herrero, José R.; Samaniego, Cristóbal (Elsevier, 2014-05)
      Article
      Accés obert
      One of the main difficulties using multi-point statistical (MPS) simulation based on annealing techniques or genetic algorithms concerns the excessive amount of time and memory that must be spent in order to achieve ...
