The cpu simulation with KPC set to multiples 32 runs fine. Now its time to port things to openCL. I have a few more questions: 1.Is it necessary to port DES_bs_set_salt() to gpu? 2. The DES_bs_crypt_25 function has too much branching in it. Is it possible to reduce the number of branching in DES_bs_crypt_25() function? Content of type "text/html" skipped
