I am new at using intel math library and have no idea how to invoke the library in my fortran routines. I have so far used Numerical Recipe subroutines for FFT and random no. purpose. Since i have to use those routines extensively in my program, i hope there will be performance gain if i use math library.
Specifically I use 2D FFT on a two dimensional real arry and a uniform random no.
Can anyone give me a walkthrough which fft routine i will use. how should i write it in my program. It would be highly appreciated if anyone can give model program which shows the steps. Since i have to use fft and uniform random no generator simultaneously, how should i compile it, specifically how to link.
I find source examples are too confusing.
This is my system con figuration:
Amd opteron dual core 2.0 HP
ifort 9.1 non comertial version
Intel mkl library 8.0.1
Any help will be highly appreciated.
