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 ... -
Exploiting Task and Data Parallelism in ILUPACK's Preconditioned CG Solver on NUMA Architectures and Many-core Accelerators
Aliaga Estellés, José Ignacio; Badía Sala, Rosa María; Barreda Vayá, Maria; Bollhöffer, Matthias; Dufrechou, Ernesto; Ezzatti, Pablo; Quintana-Orti, Enrique S. Elsevier (2016-05)We present specialized implementations of the preconditioned iterative linear system solver in ILUPACK for Non-Uniform Memory Access (NUMA) platforms and many-core hardware co-processors based on the Intel Xeon Phi and ...
