Drivers are still a big problem on FreeBSD. AFAIK neither NVIDIA nor ATI
supply GPGPU-enabled drivers for FreeBSD. If this problem were solved, I
think that most of other utilities would mostly "just work" using
standard interfaces like OpenCL.
Nvidia freebsd driver has cuda enabled. But you need the sdk to
compiled c/cuda to lowlevel cuda/asm (don't remember name now) that
driver executes on the gpu. Afaik nvidia freebsd driver hasn't opencl
support but this knowledge comes from "i don't use (tm)" opencl, so i
maybe wrong. The sdk works for Windows, Linux and MacOSX. ATI has
retired ati-stream and ati-tometal languages and support opencl in
windows and linux using a llvm private compiler.
Some days ago, a llvm opencl opensource project started (ati's one is
not opensource)
