You could use to pycuda.elementwise to shield you from any actual CUDA programming--and use [1] as a (high-quality) implementation guideline. Maybe you could even tweak that header directly (add a few __device__ specs). [1] https://svn.boost.org/trac/boost/browser/trunk/boost/math/special_functions/erf.hpp Andreas
