    Thumbs up SuperPi on GPU, were going CUDA

    The first steps were taken to port Superpi to CUDA so we should see working software in less than 30 days.

    What is CUDA?
    "The CUDA™ Toolkit is a C language development environment for CUDA-enabled GPUs."
    http://www.nvidia.com/object/cuda_learn.html

    CUDA will enable SuperPi to run on the GPU.

    We will soon be able to bench on hundreds of cores inside our GPU's for an exact performance number. This will be very interesting to massive parallel versus massive cache.

    With the success of Superpi exceeding 100 million downloads it will have an existing installed base of 70 million CUDA capable GPU's to run on and will grow by 100 million per year or so.

    Current list of CUDA enabled GPU's
    http://www.nvidia.com/object/cuda_learn_products.html

    My thanks to everyone around the world for making it one of the most popular benching applications.

    It will remain free of adverts and free to use, the program name will include CUDA GPU.

    Nice! Will there be a validation, like this: http://www.xtremesystems.com/pi/?

    It is possible to run CUDA on ATI right? Or will this be a nVidia bench only?

    I will fix validation, not sure what broke it still. It should work but it doesn't.

    I do know when it was served on IIS it does work so I may go that route with its own server.

    Not sure of current situation with ATI on GPGPU, they feel its best to exclude me.

    This should be very interesting. I suspect though that GPGPUs won't have the single-threaded speed that a 5+GHz Core 2 would have. Look forward to this though

    Aww, my 7800GTX isn't CUDA enabled... I bet it could beat a lot of the top of the line CPUs in SuperPi, though.

    I can't wait to get a new video card... It's gonna be cool to bench GPUs like this!

    while you are at it add 64m, 128m and more

    Great news i always thought that NVIDIA would do this just to get on Intel's toes.

    Hopefully this is just the beginning of GPGPU

    Woah, this is awesome.

    We will be owning CPu records I hope!

    see this is the problem.....ppl conceive all sorts of ideas over a few beers
    you can blame Vince for planting this idea in my head during dinner


    Hey Charles how can you name this SuperPi benchmark CUDA GPU and not have any reference to SuperPi

    Maybe reconsider calling it CUDA GPU SuperPi or something unless that's what you meant in first place

    Wow CUDA sounds really cool. Great news!

    Naming it with the CUDA moniker is the same as advertising IMO.

    Great news though.

    This inspired me to download the CUDA SDK and toolkit, so I did.
    But, then it got blurry.

    I hope this rocks.

    Instead of multi-threading SuperPi for CPU, make the jump and make hundreds of threads on the GPU.

    what about using those parallel processing units to compute single threaded applications

    i thought that should be doable and produce good results as well

    anyways it will be interesting to see how it all turns out and whether superpi speed will scale with the amount of cores the CPU has

    then we would have to start to tweak RAM latencies EEK
    actually that would not be very smart in case you can't go back to defaults lol

    It's not the beginning of GPGPU, not the first implementation of SPi on GPU and definitely CUDA was not made for benchmarks...it's just a byproduct.
