Fix stupid tag collision bug. RMA tag is used to order consecutive MPI_Accumulate calls.
The 454th message's tag was causing a collision with the BARRIER tag, causing the wrong message to be used.
So switch to a decrement instead, and start from a value below all of the ones we use (users can't use <0 values, it's only for internals)
