Before revision:  Although the efficient parallelization of 3D FFT has been largely investigated over the last few decades, performance and scalability of parallel 3D FFT methods on new generation hardware architecture for HPC is a major challenge.
After revision:  Performance of many scientific applications such as Molecular Dynamic simulations depends on the underlying 3D FFT has been largely investigated over the last few decades, performance and scalability of parallel 3D FFT methods on new generation hardware architecture for HPC is a major challenge.
