Assessing the impact of the CPU power-saving modes on the task-parallel solution of sparse linear systems
Aliaga Estellés, José Ignacio; Barreda Vayá, Maria; Dolz, Manuel F.; Martín Huertas, Alberto F.; Mayo, Rafael; Quintana-Orti, Enrique S. Springer US (2014)We investigate the benefits that an energyaware implementation of the runtime in charge of the concurrent execution of ILUPACK —a sophisticated preconditioned iterative solver for sparse linear systems— produces on the ... -
Exploiting thread-level parallelism in the iterative solution of sparse linear systems
Aliaga Estellés, José Ignacio; Bollhöfer, Matthias; Martín Huertas, Alberto F.; Quintana-Orti, Enrique S. Elsevier (2011)We investigate the efficient iterative solution of large-scale sparse linear systems on shared-memory multiprocessors. Our parallel approach is based on a multilevel ILU preconditioner which preserves the mathematical ... -
Leveraging Task-Parallelism in Energy-Efficient ILU Preconditioners
Aliaga Estellés, José Ignacio; Dolz, Manuel F.; Martín Huertas, Alberto F.; Mayo, Rafael; Quintana-Orti, Enrique S. Springer Berlin Heidelberg (2012)We analyze the energy-performance balance of a task-parallel computation of an ILU-based preconditioner for the solution of sparse linear systems on multi-core processors. In particular, we elaborate a theoretical model ... -
Parallelization of Multilevel ILU Preconditioners on Distributed-Memory Multiprocessors
Aliaga Estellés, José Ignacio; Bollhöfer, Matthias; Martín Huertas, Alberto F.; Quintana-Orti, Enrique S. Springer Berlin Heidelberg (2012)In this paper we investigate the parallelization of the ILUPACK library for the solution of sparse linear systems on distributed-memory multiprocessors. The parallelization approach employs multilevel graph partitioning ...
