The compute unified device architecture (cuda) enables nvidia graphics processing units (gpus) to be used for massively parallel general purpose computation.

the fft is a divide-and-conquer algorithm for efficiently computing discrete fourier transforms of complex or real-valued data sets. it is one of the most important and widely used numerical algorithms in computational physics and general signal processing. the cufft library provides a simple interface for computing ffts on an nvidia gpu, which allows users to quickly leverage the floating-point power and parallelism of the gpu in a highly optimized and tested fft library.

this package contains the cufftw runtime library.
