I played around with FFTW's support of multi-threaded FFTs on a dual-proc (not dual-core) machine a few years ago. It was slower unless you were doing a transform with 100,000 points or so. (Or thereabouts.) Unless things have changed drastically, it was rather dissapointing and, obviously, not worth it. > > Feel free to try it out :) > > Eric > > > _______________________________________________ > Discuss-gnuradio mailing list > [email protected] > http://lists.gnu.org/mailman/listinfo/discuss-gnuradio -- Joshua Lackey, PhD. -- [EMAIL PROTECTED] _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
