No, but I know that radio astronomers do this. I have done FFT with CUDA. As long as you can keep the data inside the GPU for long enough, you can get pretty nice performance. I have measured over 100 GFLOPS on FFT with a $300 Nvidia GPU. I haven't tried yet with my new 480 GTX, but it should be even faster. juha _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
