Parallel 3D FFT is a commonly used numerical method inscientific computing. P3DFFT is a recently proposed implementationof parallel 3D FFT that is designed to allow scalability to massivelylarge systems such as Blue Gene. While there has been recent workthat demonstrates such scalability on regular cartesian meshes (equallength in each dimension), its performance and scalability for flat cartesianmeshes (much smaller length in one dimension) is still a concern. Inthis paper, we perform studies… CONTINUE READING
