4X faster calculations with UNC GAMMA FFT library

Post by dgebel »

Article on slashdot about a new FFT library, which I'm wondering if Blender could make use of.

A reader writes: "The UNC GAMMA group has recently released a high performance FFT library which can handle large 1-D FFTs. According to their webpage, the FFT library is able to achieve 4x higher computational performance on a $500 NVIDIA 7900 GPU than optimized Intel Math Kernel FFT routines running on high-end Intel and AMD CPUs costing $1500-$2000. The library is supported for both Linux and Windows platforms and is tested to work on many programmable GPUs. There is also a link to download the library freely for non-commerical use."

From the download page:
"GPUFFTW is free for noncommercial use only. Click here for the terms of this distribution."


... so it's not compatible with the GPL then
[it's also not compatible with ATI cards... yet]
