Solving advection equations with reduction multigrids on GPUs
S. Dargaville, R. P. Smedley-Stevenson, P. N. Smith +1
Methods for solving hyperbolic systems typically depend on unknown ordering (e.g., Gauss-Seidel, or sweep/wavefront/marching methods) to achieve good convergence. For many discreti…

Coarsening and parallelism with reduction multigrids for hyperbolic Boltzmann transport
S. Dargaville, R. P. Smedley-Stevenson, P. N. Smith +1
Reduction multigrids have recently shown good performance in hyperbolic problems without the need for Gauss-Seidel smoothers. When applied to the hyperbolic limit of the Boltzmann…
