We present a parallel time-domain simulator to solve the acoustic wave equation for large acoustic spaces on a distributed memory architecture. Our formulation is based on the adaptive rectangular decomposition (ARD) algorithm, which performs acoustic wave propagation in three dimensions for homogeneous media. We propose an efficient parallelization of the different stages of the ARD pipeline; using a novel load balancing scheme and overlapping communication with computation, we achieve… CONTINUE READING
