ROOM:Mile High Pre-Function

ABSTRACT:
We present a method to design and auto-tune a new parallel 3-D FFT code using the non-blocking MPI all-to-all operation. Preliminary results show that we maximize computation-communication overlap, and execute 3-D FFT faster than the MPI-enabled FFTW library by up to 1.76x.
