FUGGER unveiled at the Xtreme Systems forums that SuperPI will get the CUDA-treatment. He says that within a month or so there should be a version of SuperPI that uses GeForce 8 and 9 series graphics cards to calculate pi:
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.
