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. Lukas
