Abstract

Realistic ultrasound simulations are becoming integral part of many novel medical
procedures such as photoacoustic screening and non-invasive treatment planning.
The common denominator of all these applications is the need for cheap and
relatively large-scale ultrasound simulations with sufficient accuracy. Typical
medical applications require full-wave simulations which take frequency-dependent
absorption and non-linearity into account. This poster investigates the benefits
of high-bandwidth low-latency interconnects to k-Wave acoustic toolbox in dense
multi-GPU environment. The k-Wave multi-GPU code is based on a variant of the
local Fourier basis domain decomposition. The poster compares the behavior of the
code on a typical PCI-E 3.0 machine with 8 Nvidia Tesla P40 GPUs and a Nvidia
DGX-2 server. The performance constraints of PCI-E platforms built around
multiple socket servers on multi-GPU applications are deeply explored. Finally,
it is shown the k-Wave toolbox can efficiently utilize NVlink 2.0 and achieve
over 4x speedup compared to PCI-E systems.
