Traditionally the GPU has been used almost exclusively for floating-point operations, because integer operations could only be done using the mantissa of floats; thus, processes that required bitwise logical operations were impossible. Another issue was that we had to render the output of the GPU to textures or pixel buffers before we could get to our results. Therefore, to process streaming data, we needed to write tricky graphics code.

However, with the advent of the new GeForce 8 Series GPU, several new extensions and functions ...
