GPU cracking is too slow

[khawasli]

gpus work on massively parallel problems, so you can only achieve full acceleration on gpu if you give the gpu enough work to do. a straight dictionary attack does not give the gpu enough work. in order to achieve full acceleration, you have to run an attack with a large enough keyspace. try adding '-r rules/d3ad0ne.rule' to the end of your command.

Radeon 290X is the best card at the moment.

Thanks again for your reply. Is there a place where I can read a description on that rule? I googled it and could find much details about it.

What about regular bruteforcing (without a dictionary) do GPUs work well with that type of attack?
