Unfortunately, (using a CPU slot for the same work unit) TPF is 2-3 times
slower than on Ubuntu for me. Much of the speed difference seems to be related
to libOpenCL. If remove libOpenCL on Ubuntu, it's still 20-30% faster than on
FreeBSD.

Don't know how stable the TPF numbers are, so numbers may be bogus.

Will a CPU slot also use the GPU with libOpenCL or is it just using better
optimized code? I tried to install libOpenCL but all I get is:
OpenCL: Not detected: clGetPlatformIDs() returned -1001

Since there's no CUDA support for FreeBSD, I guess there is no point in trying
getting GPU slots to work.
