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

© 2020 Elsevier Inc. 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 scalability by departing from the usual propagation pattern, in which information flows in a 180∘ degree...
