    • closedAccess   Assessing the Performance-Energy Balance of Graphics Processors for Spectral Unmixing 

      Sánchez, S.; León Navarro, Germán; Plaza, Antonio; Quintana-Orti, Enrique S. IEEE (2014)
      Remotely sensed hyperspectral imaging missions are often limited by onboard power restrictions while, simultaneously, require high computing power in order to address applications with relevant constraints in terms of ...

    • closedAccess   Blocked algorithms for the reduction to Hessenberg-triangular form revisited 

      Kagstrom, B.; Kressner, Daniel; Quintana-Orti, Enrique S.; Quintana-Ortí, Gregorio Springer (2008-09)
      We present two variants of Moler and Stewart’s algorithm for reducing a matrix pair to Hessenberg-triangular (HT) form with increased data locality in the access to the matrices. In one of these variants, a careful ...

    • openAccess   Highly sensitive and ultrafast read mapping for RNA-seq analysis 

      Barrachina Mir, Sergio; Castillo Catalán, María Isabel; Martínez Pérez, Héctor; Medina, Ignacio; Tárraga, Joaquín; Quintana-Orti, Enrique S.; Dopazo, Joaquín; Salavert Torres, José; Blanquer Espert, Ignacio; Paschall, J.; Hernández-García, V. Oxford University Press (2016)
      As sequencing technologies progress, the amount of data produced grows exponentially, shifting the bottleneck of discovery towards the data analysis phase. In particular, currently available mapping solutions for RNA-seq ...

    • closedAccess   Reproducibility strategies for parallel Preconditioned Conjugate Gradient 

      Iakymchuk, Roman; Barreda Vayá, Maria; Wiesenberger, Matthias; Aliaga Estellés, José Ignacio; Quintana-Orti, Enrique S. Elsevier (2020-01-02)
      The Preconditioned Conjugate Gradient method is often used in numerical simulations. While being widely used, the solver is also known for its lack of accuracy while computing the residual. In this article, we aim at a ...
