• openAccess   Characterization of Multicore Architectures using Task-Parallel ILU-type Preconditioned CG Solvers 

      Aliaga Estellés, José Ignacio; Barreda Vayá, Maria; Quintana-Orti, Enrique S. (2017-07-05)
      We investigate the eficiency of state-of-the-art multicore processors using a multi-threaded task-parallel implementation of the Conjugate Gradient (CG) method, accelerated with an incomplete LU (ILU) preconditioner. ...
    • openAccess   Harvesting Energy in ILUPACK via Slack Elimination 

      Aliaga Estellés, José Ignacio; Barreda Vayá, Maria; Castaño Álvarez, María Asunción (2017-07-05)
      We develop a new energy-aware methodology to improve the energy consumption of a task-parallel preconditioned Conjugate Gradient iter- ative solver on a Haswell-EP Intel Xeon. This technique leverages the power-saving ...
