      We investigate the benefits that an energy-aware implementation of the runtime in charge of the concurrent execution of ILUPACK—a sophisticated preconditioned iterative solver for sparse linear systems—produces on the ...
    • Iteration-fusing conjugate gradient for sparse linear systems with MPI + OmpSs 

      Barreda, María; Aliaga, José I; Beltran, Vicenç; Casas, Marc (Springer Link, 2020)
      Open Access
      In this paper, we target the parallel solution of sparse linear systems via iterative Krylov subspace-based method enhanced with a block-Jacobi preconditioner on a cluster of multicore processors. In order to tackle ...
