Exploiting nested task-parallelism in the $\mathcal{H}-LU$ factorization

Rocío Carratalá-Sáez, Sven Christophersen, José I. Aliaga +3

We address the parallelization of the LU factorization of hierarchical matrices ($\mathcal{H}$-matrices) arising from boundary element methods. Our approach exploits task-paralleli…
