NPB FT benchmark optimization FFTW port of FT.

For Benchmarking this FT port performance on your machine download NPB3.3.1 from http://www.nas.nasa.gov/Software/NPB/

1. Replace & rename this file in NPB3.3.1/NPB3.3-MPI/FT/ as ft.f
2. Configure compiler & other optimzation, in configuration file.
3. Run & compare perfomance of FFTW 3D routines on your machine.
