As and FYI, Daniel J. Bernstein and a few other authors have created a
new high level language for NVIDIA GPU's called qhasm-cudasm
http://binary.cr.yp.to/gpuasm-20120313.pdf . I believe it will work on
AMD/ATI as well, but focused on Nvidia. It does not appear to be be
available for download yet, perhaps a email to DJB would let us know
where to find it. I've not read the whole paper, but it may be of
interest for future developments in the GPU area. While the paper
itself focuses on encryption, I'm sure it has many other uses as well.
