Yes, that would be perfectly fine. How can I do this? Specifically, how do I get the ID of the worker? And can I then just use a counter field in my computation which I increase whenever I need a new ID?
(So my global ID would be a pair of the worker ID and the number I derived from incrementing the counter).
