Semantics for MPI_NOPRECEDE and MPI_NOSUCCEED.
MPI_NOPRECEDE
This barrier does not complete a sequence RMA calls either originating
or targetted at this process. If this assertion is given by any process
in the window group then it must be given by all processes in the window
group. If the assertion MPI_NOSUCCEED is also given then MPI_WIN_BARRIER
is a no-op.
MPI_NOSUCCEED
This barrier does not start a sequence of RMA calls either originating
or targetted at this process. If this assertion is given by any process
in the window group then it must be given by all processes in the window
group. If the assertion MPI_NOPRECEDE is also given then MPI_WIN_BARRIER
is a no-op.
