https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/how-to-use-intel-math-library/m-p/911274#M12179 Hi everybody,<BR /> 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.<BR /><BR /> Specifically I use 2D FFT on a two dimensional real arry and a uniform random no.<BR /><BR />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.<BR /><BR />I find source examples are too confusing.<BR />This is my system con figuration:<BR />Amd opteron dual core 2.0 HP<BR />ifort 9.1 non comertial version<BR />Intel mkl library 8.0.1<BR /><BR />Any help will be highly appreciated.<BR /> anupam<BR /> <BR /> Thu, 14 Sep 2006 16:52:54 GMT anupam_mu 2006-09-14T16:52:54Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/how-to-use-intel-math-library/m-p/911274#M12179 Hi everybody,<BR /> I am new at using intel math library and have no idea how to invoke the library in my fortran routines.
