simpleCUFFT_2d_MGPU - SimpleCUFFT_2d_MGPU

Description

Example of using CUFFT. In this example, CUFFT is used to compute the 2D-convolution of some signal with some filter by transforming both into frequency domain, multiplying them together, and transforming the signal back to time domain on Multiple GPU.
