Case Study on Multi-domain Decomposition of k-Wave Simulation Framework

Original language description

This article describes both advantages and challenges of using GPU equipped clusters to implement efficient distributed algorithms. Our main focus is the decomposition of numerical simulations based on (pseudo-)spectral methods. We use a pseudo-spectral simulation of ultrasound wave propagation in homogenous medium (k-Wave) as a showcase of distributed algorithm. We show that we are able to achieve three fold speedup of the simulation while lowering the cost at the same time by employing a Local Fourier Basis decomposition.
