First of all you should not use mpi with cuda. For now it will not give you
any speedup. If you have got 8 gpus try -gpu option (you can select only
one for now) and for example different type of attacks for each gpu, or
generate candidates with --stdout option, divide it for 8 parts and then
try each part for one gpu + rules.

There was bug in cuda-1 version I fixed it already, and now I am trying to
upload it to wiki (I am having problems with ISP), so it will be available
on wiki ASAP.
