I can not help you to define the problem you need to solve ;-) If you clarify the synchronization points between the 6 threads tis would surely help. Take in account that we are not aware of your problem domain
Maybe you just need to have 3 barriers, one for each group of the 3 threads and an additional one to synchronize the end of the 6 threads. HTH, Vicente
