FYI: As much as Intel likes to say that you can "just run" MPI/MPI+OpenMP code on MIC, you will probably not be impressed with the performance (it will be *much* slower than a Xeon CPU).
If you want to know why and what/when are we doing something about it, please read my earlier comments on MIC posted to the mailing list. -- Szilárd On Thu, Mar 21, 2013 at 1:49 PM, Mark Abraham <[email protected]>wrote: > Yes, you can use any kind of FFTW installation for correct results. > Hardware for which FFTW provides no SIMD acceleration will have to fall > back on the generic FFTW routines.
