Annotation

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.
