Subject: 2-d IMSL fft -> gfortran
Hello,
I have obtained a relatively old fortran code that uses 2-d IMSL
FFT routines, forward and inverse.
Is there a gfortran implementation available that I can substitute?
I'm not a fortran programmer, so ...
As far as I can tell, the rest of the code is standard fortran, so
any optimization flags to get this
code running as fast as possible would be helpful.
I'm running on a Mac OSX Tiger Intel 64-bit machine.

According to the first part of your message, you wanted a replacement for the IMSL functions, so it's not so much a question of optimization flags, until you choose an open source fft. You might also consider the Intel MKL library, which should work fine with gfortran.
