Hiya Cluster Physik,

Do you know of any any FFT libs compatible w/ ATI GPU?

Raistmer @ Lunatics could use some input from you on this.

Thx!!!

As far as I know there is nothing freely available. If one don't want to write that on his own, one would have to ask ATI for it. Maybe they can provide him with something. Sorry.

Thanks for the reply!

One should really ask AMD about it. I've seen some FFT performance comparisons from them. They claimed a HD4870 to be 75% faster than a 9800GTX and about 15-20% faster than a GTX280. I wonder what code they have used for that comparison.

Hummm...this is VERY interesting. I'll pass it on to Raistmer. Thanks again : > )
