There are now two versions of the code available for download. It is recommended that users try the FFTW only version of the code, as all of the required software is freely available and it allows for greater flexibility in choosing the size of the simulation. The IPP version is still available should one desire the ability to conduct faster simulations.

It may be helpful to read over the fftw version readme or the ipp version readme file first.

A version of the code has also been written that utilizes message passing to transmit data between the filefftw processes and PMFAST - this can be obtained from the author. It optimally results in accessing a shared-memory segment, which is mediated by the operating system in the case of the file transfer method.

For questions pertaining to installation or execution of the code please contact Hugh Merz.
