L-Sweeps: A scalable, parallel preconditioner for the high-frequency Helmholtz equation

Matthias Taus, Leonardo Zepeda-Núñez, Russell J Hewett +1

We present the first fast solver for the high-frequency Helmholtz equation that scales optimally in parallel, for a single right-hand side. The L-sweeps approach achieves this scal…
