Implementation of 3D FFTs Across Multiple GPUs in Shared Memory Environments

Nandapalan, Nimalan; Jaros, Jiri; Rendell, Alistair; Treeby, Bradley


In this paper, a novel implementation of the distributed 3D Fast Fourier Transform (FFT) on a multi-GPU platform using CUDA is presented. The 3D FFT is the core of many simulation methods, thus its fast calculation is critical. The main bottleneck of the
