This talk/poster investigates the performance of the distributed k-Wave toolbox on Barbora, Karolina and LUMI clusters. The solver uses 1D decomposition of the k-space corrected pseduospectral method heavily employing the distributed FFTW library. The goal is to show the strong and weak scaling on domains up to 3072^3 grid points (3.6TB of RAM) using up to 3072 compute cores. The comparison also investigates the computation/communication ratio and several low level performance statistics.
