Much of the speed difference seems to be rel= ated 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 tr= ying getting GPU slots to work.
