But I see your point that much of this particular computation can be done on the GPU, up to probably quite high limits. Replace this example with your choice of non-data-parallel computation.</div><div><br></div><div>Very sexy demos, by the way.</div><div><br></div><div>Regards,</div><div>Maciej</div><div><br></div></body></html>
