    Atomic operations needed when work group  size <= size of wave front ?


      Do I need to worry about atomic operations if work group size is <= 64 ? From previous discussion,

      I do not need memory barriers for this size of work group.


      My situation is: I have all work items ORing the same location in a local memory array.
