DiGPUFFT (“dig-puffed”): Distributed GPU FFTs

Chris has released  DiGPUFFT  (pronounced, “dig-puffed”), a set of code patches that add GPU capabilities to P3DFFT, Dmitry Pekurovsky’s distributed memory 3D FFT library. A technical report describing these patches and our performance results for the Keeneland system at ORNL is in the works; it should appear on the DiGPUFFT website later this month or early next.
