You could do something like MPI_Gather() for the value of v into a local
variable and have a logic for that variable so that it shows whether v
has been changed at least by one of the processes. In that case, based
on the new variable, introduce the Bcast() or not? Just a suggestion.
There might be a much better and straight forward way.
