Simple FFT question

Hi,
What is the batch option in CUFFT for? if I have 100 2D ffts to do, will a batch run faster than 100 single 2D ffts?

thanks

If you have a bunch of FFT’s of the same size that you need to do, it’s generally faster to run them in one batch rather than in multiple separate calls, yes.

Thanks a lot Cliff, I’ll give it a try…
