    • openAccess   Out-of-Core Solution of Linear Systems on Graphic Processors 

      Castillo Catalán, María Isabel; Igual, Francisco; Mayo, Rafael; Rubio, Rafael; Quintana-Ortí, Gregorio; Quintana-Orti, Enrique S.; Van de Geijn, Robert A. Departament d' Enginyeria i Ciència dels Computadors, Universitat Jaume I (2008-05)
      We combine two high-level application programming interfaces to solve large-scale linear systems with the data stored on disk using current graphics processors. The result is a simple yet powerful tool that enables a ...

    • openAccess   Solving Dense Linear Systems on Graphics Processors 

      Barrachina Mir, Sergio; Castillo Catalán, María Isabel; Igual, Francisco; Mayo, Rafael; Quintana-Orti, Enrique S. Departament d' Enginyeria i Ciència dels Computadors, Universitat Jaume I (2008-02)
      We present several algorithms to compute the solution of a linear system of equations on a GPU, as well as general techniques to improve their performance, such as padding and hybrid GPU-CPU computation. We also show how ...

    • closedAccess   Toward the parallelization of GSL 

      Aliaga Estellés, José Ignacio; Almeida, Francisco; Badía, José; Barrachina Mir, Sergio; Blanco, Vicente; Castillo Catalán, María Isabel; Mayo, Rafael; Quintana-Orti, Enrique S.; Quintana-Ortí, Gregorio; Remón Gómez, Alfredo; Rodríguez, Casiano; De Sande, Francisco; Santos, Adrián Springer-Verlag (2009)
      In this paper, we present our joint efforts to design and develop parallel implementations of the GNU Scientific Library for a wide variety of parallel platforms. The multilevel software architecture proposed provides ...

    • closedAccess   Unveiling the performance-energy trade-off in iterative linear system solvers for multithreaded processors 

      Aliaga Estellés, José Ignacio; Anzt, Hartwig; Castillo Catalán, María Isabel; Fernández Fernández, Juan Carlos; León Navarro, Germán; Pérez, Joaquín; Quintana-Orti, Enrique S. Wiley (2015)
      In this paper, we analyze the interactions occurring in the triangle performance-power-energy for the execu- tion of a pivotal numerical algorithm, the iterative conjugate gradient (CG) method, on a diverse collection ...
