1,048,576 pt FFT using MKL

1,048,576 pt FFT using MKL


I'm trying to see if a 3.66 GHz Xeon has enough processing power for a upcoming project.

As such, can someone tell me how many seconds it will take the MKL's FFT routine to process and 1,048,576 point single precision real-data FFT?

I'm not sure how to obtain this information from looking at the GFLOPS charts that's on the webpage.

Thank you.
