    • openAccess   An Algorithm-by-Blocks for SuperMatrix Band Cholesky Factorization 

      Quintana-Ortí, Gregorio; Quintana-Orti, Enrique S.; Remón Gómez, Alfredo; Van de Geijn, Robert A. Springer Verlag (2008)
      We pursue the scalable parallel implementation of the factor- ization of band matrices with medium to large bandwidth targeting SMP and multi-core architectures. Our approach decomposes the computation into a large ...

    • closedAccess   Modeling power and energy of the task-parallel Cholesky factorization on multicore processors 

      Alonso-Jordá, Pedro; Dolz, Manuel F.; Mayo, Rafael; Quintana-Orti, Enrique S. Springer Berlin Heidelberg (2014-05)
      In this paper we introduce a model for the total energy consumption of the Cholesky factorization on a multicore processor. Our model assumes a task-parallel execution of the factorization process, with concurrency leveraged ...
