FFT library for ATI GPU - does it exist?

Hello

AFAIK current ACML-GPU release doesn't use GPU for FFT routines. Does any FFT library exist that make use of ATI GPUs ?

Well, I rephrase:

When FFT on ATI GPUs will be supported in ACML ?

CUDA had it's CUFFT library from very first release BTW

Library in CUDA working with 1 % of decleared GPU perfomance. Better to use Ipp or library for AMD then the CUDA.

E, ne skagi.
Poprobuj CUFFT 2.3, suschestvenno shustree stalo.
Opyat' ge, esli vse na GPU delat', to IPP/ACML/FFTW potrebuyut chtoby snachala dannye peregnal v osnovnuyu pamyat', a potom rezul'taty preobrazovaniya obratno v GPU.
Nakladnyh rashodov more. Tak chto vopros actualen.

In short, using CPU FFT libraries required data copy to/from host memory - too costly operation to be efffective.

Did they released new version?
Inital version had no GPU acceleration for FFT, only some GPU BLAS routines AFAIK.

ATI Stream-accelerated routines:

SGEMM
DGEMM

to Raistmer:

Nado gnat PCIex i brat kachestvennuu mat chtoby pre peredachi dannyh po PCIex ne prihodilos peredavat po 20 raz

Polnostu soglasen po povodu vse na GPU, no est i svoi tonkosti. Naprimer nado sdelat 2D FFT na 9Gb dannyh i tut uzh...
