> e.g. you were adding several small positive integers together from a shared data structure in parallel, but due to a misunderstanding in your design this was actually a data race, and some time later somehow your total is now zero Could you clarify why/how this would happen? Is it because the last process sets it to zero to initialize a variable? I can’t conceptualize the steps that would end up with this result if all processes are adding. It seems like it would at least equal the result of the final thread’s calculation.
