It appears that there's really only one problem, and that is likely the one indicated here: kernel.cu: In function `md5_rng_int': kernel.cu:87: warning: this decimal constant is unsigned only in ISO C90 (repeated many times) Note that this occurs in the random number generator. Then all the other failures you are seeing indicate that the RNG spit out NaNs, which again I presume is a consequence of whatever is being warned about above. To try and fix the immediate warning, can you try and add 'u' after all the integer literals in pycuda/curandom.py and let us know if that fixed it? I.e. you would rewrite FF ( c, d, a, b, X2 , S13, 606105819); as FF ( c, d, a, b, X2 , S13, 606105819u); HTH, Andreas
