| Ultrasound simulation
is a critical component of model-based treatment planning for
ultrasound therapy. However, the domain sizes are typically thousands of
wavelengths in size, leading to large-scale numerical models with 10s
of billions of unknowns. This paper presents a novel local Fourier basis
domain decomposition for full-wave ultrasound propagation simulations
with a custom bell function which ensures that the numerical error is
below 0.1% while enabling almost ideal strong scaling.
Realistic benchmarks with 6144 Haswell cores across 256 Salomon nodes
show significant improvement over native 3D FFT decomposition. |
