+Force a specific workgroup size for *all* the gpus.

+With no param, or 0, the miner auto detects what he thinks is the best setting for each GPU.  
+If you run with `-d`, it will display the auto detected workgroup size.
+The defaults should be ok for most GPU.  
+You can try to enforce a higher size than what is auto detecte on some systems (like AMDs).  
+*Beware:* setting too high a value **will** make your gpu crash.
