Abstract
In this paper, I describe a framework for spectral transforms called P3DFFT, and its extended features and applications. I discuss the scaling seen on petascale platforms, and directions and some results of the ongoing work on improving performance, such as overlap of communication with computation and hybrid MPI/OpenMP implementation.
