cgminer blah blah -d 0 -g 2 -d 1 -g 1 ....
Card 0 will have 2 thread and card 1 will have 1 thread.
Thanks a lot man!!
Finally my multicard rig can work with one instance!
I am fairly certain that you cannot do it this way. You need to run another instance of cgminer to run different thread settings.
I get exactly the same hash/s with multicard and -d (--device not disable) like every card in a single card setup. Don't know if they really get 1 or 2 thread but the result say me it's working.
