Webspecific APIs. NVIDIA’s FFT library, CUFFT [16], uses the CUDA API [5] to achieve higher performance than is possible with graphics APIs. Concurrent work by Volkov and Kazian … WebThis is a shared memory implementation of the fast Fourier transform (FFT) on CUDA GPUs for Astro-Accelerate project. Compile: 'make' should do that. You may need to define CUDA_HOME parameter. Implementations: There are two implementations of the FFT algorithm Cooley-Tukey and Stockham FFT algorithm.
