A more clear headed Shared setup in data
Still many problems

Small problem, getting the wrong answers.
    check gpu/test.py for code to compare to right rms
Big problem, even multiprocessing may be unsafe
    getting following error:

    dirac.rankMatchingScores( srt.gpu_data, rt.gpu_data, rms.gpu_data, nm.gpu_data, srt.buffer_nsamples, nm.buffer_nnets, sample_block_size, nets_block_size)
