On the Reynolds-number scaling of Poisson solver complexity
F. Xavier Trias, Ãdel Alsalti-Baldellou, Assensi Oliva
We aim to answer the following question: is the complexity of numerically solving the Poisson equation increasing or decreasing for very large simulations of incompressible flows?…

Exploiting repeated matrix block structures for more efficient CFD on modern supercomputers
Josep Plana-Riu, F. Xavier Trias, Ãdel Alsalti-Baldellou +3
Computational Fluid Dynamics (CFD) simulations are often constrained by the memory-bound nature of sparse matrix-vector operations, which eventually limits performance on modern hi…
