Hi Mitch,

Clover is still being developed and has been merged into the Mesa codebase:
http://cgit.freedesktop.org/mesa/mesa/

Currently the only hardware supported by clover are AMD
Evergreen and Northern Islands (besides Cayman) GPUs.  See
http://dri.freedesktop.org/wiki/GalliumCompute for more information.

Clover uses libclc as the standard library implementation for OpenCL C and links
OpenCL kernels against it.

Hope this helps.
