A case for malleable thread-level linear algebra libraries: The LU factorization with partial pivoting

Catalán, Sandra; Herrero, José R.; Quintana Ortí, Enrique Salvador; Rodríguez-Sánchez, Rafael; van de Geijn, Robert (Institute of Electrical and Electronics Engineers, 2019-01-31)

[EN] We propose two novel techniques for overcoming load-imbalance encountered when implementing so-called look-ahead mechanisms in relevant dense matrix factorizations for the solution of linear systems. Both techniques ...
Two-sided orthogonal reductions to condensed forms on asymmetric multicore processors

Alonso-Jordá, Pedro; Catalán, Sandra; Herrero, José R.; Quintana-Ortí, Enrique Salvador; Rodríguez-Sánchez, Rafael (Elsevier, 2018-12)

[EN] We investigate how to leverage the heterogeneous resources of an Asymmetric Multicore Processor (AMP) in order to deliver high performance in the reduction to condensed forms for the solution of dense eigenvalue and ...
