Computation–communication overlap and parameter auto-tuning for scalable parallel 3-D FFT

•We design a new method of parallel 3-D FFT based on 2-D decomposition of an input 3-D array.•We optimize the performance through computation–communication overlap and parameter auto-tuning.•Experimental results from two supercomputers confirm that our method is faster than three existing libraries....
