• openAccess   Communication in task-parallel ILU-preconditioned CG solversusing MPI + OmpSs 

      Aliaga Estellés, José Ignacio; Barreda Vayá, Maria; Flegar, Goran; Bollhöffer, Matthias; Quintana-Orti, Enrique S. Wiley (2017-11-10)
      We target the parallel solution of sparse linear systems via iterative Krylov subspace–based methods enhanced with incomplete LU (ILU)-type preconditioners on clusters of multicore processors. In order to tackle large-scale ...
    • openAccess   Energy‐aware strategies for task‐parallel sparse linear system solvers 

      Aliaga Estellés, José Ignacio; Barreda Vayá, Maria; Castaño, Asunción Wiley (2018)
      We present several energy‐aware strategies to improve the energy efficiency of a task‐parallel preconditioned Conjugate Gradient (PCG) iterative solver on a Haswell‐EP Intel Xeon. These techniques leverage the power‐saving ...
