AccFFT: A library for distributed-memory FFT on CPU and GPU architectures
We present a new library for parallel distributed Fast Fourier Transforms (FFT). The
importance of FFT in science and engineering and the advances in high performance
computing necessitate further improvements. AccFFT extends existing FFT libraries for
CUDA-enabled Graphics Processing Units (GPUs) to distributed memory clusters. We use
overlapping communication method to reduce the overhead of PCIe transfers from/to GPU.
