Sales point
It enables us to efficiently perform three- and four dimensional FFT in an arbitrary size. The library exhibits a good performance on the K-computer and PC clusters because of an optimized data structure minimizing the communication volume for a given number of MPI processes. It is easy to introduce the library for C and Fortran programs using the well developed interface.

Related Application
FFTW3 is required.
