High performance FFT on GPUs

Posted by ryuzaki0 on from the testing-it-out dept.

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."

  1. Final Fantasy Tactics? by Musteval · · Score: 4, Funny

    Why use a GPU for Final Fantasy Tactics? Couldn't you just use the GBA?

      Seriously! I mean, with only 1-D, it's really going to suck. I know people have accused Final Fantasy of being too linear in the past, but this is getting a bit silly...now, we're stuck at a single point!

    I have an uncle who's a professor who's been using GPUs for scientific computation for years.

    I'm sorry, but playing Quake at really high framerates does not count as research. He's not fooling anyone.

    The business cards which list him as 'Profess0r of Pwnage' probably aren't helping either.

    It's also bad when he refers to the undergrads as 'n00bs' during his lectures to them.

    FFT is a data compression and encryption standard used by a wide variety of extraterrestrial civilizations. Seti@home spends most of its time running FFT code to look for signals. If we managed to communicate with any of these aliens we could ask them what it stands for.

    Doesn't it make you feel good to know that our freedoms are protected by politicans, lawyers and journalists.

    Finally I have a good excuse to give the IT department why I need to upgrade my video card. I need to do FFTs faster (it has nothing at all to do with Doom3).
