CUDA vs SSE

We all know that GPUs can be incredibly fast at some single precision floating point algorithms.
Developers of BitMagic Library Igor Tolstoy and Anatoliy Kuznetsov made an attempt to implement parallel bit-stream transposition and similarity algorithm (a lot of bit-shifting, population counting and general purpose integer logic) to better understand CUDA and GP-GPU computing in comparison with current (and future) Intel vectorization architectures (SSE2).
