It was master from couple of weeks ago. The problem is in salsa_kurnel.cu In cuda_scrypt_core(int thr_id, int stream, unsigned int N) Line:     dim3  grid(WU_PER_LAUNCH/WU_PER_BLOCK, 1, 1); That WU_PER_BLOCK is zero....

Just copy API from sgminer.

Cudaminer and sgminer have similar codebase, so copying API from one to another is the Least Significant Change. Some adaptation will be required, of course.
