Thanks for posting your experience.
One of the places I've wondered if we might sneak a look at GPUs near
term would be as one or more, new internal functions for use with
isosurfaces. Specifically isosurfaces needing to evaluate a great many
functions for each evaluation - something not practical today.
Last I looked for my Ubuntu platform (14.04), OpenCL looked messy to
install and run. I bailed before attempting anything!
