I had to change "char build_opts[64]" to "char build_opts[64] = {0};" in init() in order to get this to run, otherwise it would fail with the following error:
OpenCL error (CL_INVALID_DEVICE) in file (common-opencl.c) at line (969) - (Error while getting build info I)
For some reason I'm seeing half the speeds you're seeing on 290X.
