Abstract: SUMMARYThe method of polarized traces provides the first documented algorithm with truly scalable complexity for the highfrequency Helmholtz equation, i.e., with a runtime sublinear in the number of volume unknowns in a parallel environment. However, previous versions of this method were either restricted to a low order of accuracy, or suffered from computationally unfavorable boundary reduction to O(p) interfaces in the p-th order case. In this note we rectify this issue by proposing a high-order method of p…
