    Stream compaction

    I'm facing a stream compaction problem, exactly as described in sect. 39.3.1 of

    http.developer.nvidia.com/GPUGems3/gpugems3_ch39.html

    My vector is in global memory and I have to compact it and place the result back in global memory. In the above cited article it is mentioned that
    The addition of a native scatter in recent GPUs makes stream compaction considerably more efficient
    Still, I cant understand the exact meaning of that sentence. Are there native OpenCL C instructions that allows to compact streams in global memory? More generally, which is the best way to compact a vector?
    Thanks
