High performance FFT on GPUs
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."
I'm too lazy to go and look for a definition to FFT, and the article (or webpage describing the software) was short on details.
Enlighten me, please!
Back then computer programmers were paid better as well. Seems people want the cost of the programmer to favorably compare to the cost of the hardware!
