I think all of these, and maybe more, lack auto-tuning:
$ fgrep '1024*9' *.c
opencl_agilekeychain_fmt.c:#define KEYS_PER_CRYPT 1024*9
opencl_dmg_fmt.c:#define KEYS_PER_CRYPT 1024*9
opencl_keychain_fmt.c:#define MIN_KEYS_PER_CRYPT 1024*9
opencl_odf_aes_fmt.c:#define MIN_KEYS_PER_CRYPT 1024*9
opencl_odf_fmt.c:#define MIN_KEYS_PER_CRYPT 1024*9
opencl_strip_fmt.c:#define MIN_KEYS_PER_CRYPT 1024*9
opencl_zip_fmt.c:#define MIN_KEYS_PER_CRYPT 1024*9
