Default parallel FFT with OpenFoam?

henman is on a distinguished road
I created a 3-D turbulent velocity field with periodic boundaries in a very large domain (1024^3) and want to get the spectral shape of this field. My creating code is not able to perform FFT on parallel machines, so I'd like to know if this is easily feasible in OpenFoam. Data is available in an ieee16-binary file.
I am completely new to OpenFoam, so I think it only makes sense for me if I do not have to change the code but just have to use prepared modules.
Thanks for your help!
