Overlapping of Communication and Computation in nb3dfft for 3D Fast Fourier Transformations
Overlapping of Communication and Computation in nb3dfft for 3D Fast Fourier Transformations
For efficiency and accuracy of Direct Numerical Simulations(DNS) of turbulent flows pseudo-spectral methods can be employed,where the governing equations are solved partly in Fourier space. Theinhouse-developed 3d-FFT library nb3dfft is optimized to the specialneeds of pseudo-spectral DNS, particula...

For efficiency and accuracy of Direct Numerical Simulations(DNS) of turbulent flows pseudo-spectral methods can be employed,where the governing equations are solved partly in Fourier space. Theinhouse-developed 3d-FFT library nb3dfft is optimized to the specialneeds of pseudo-spectral DNS, particularly for the scientific code psOpen,used by the Institute for Combustion Technology at RWTH Aachen Uni-versity. In this paper we discuss the method of overlapping communica-tion and computation of multiple FFTs at the same time. |
