MPI "universe" yes, but not necessarily MPI "world". You could have
the two worlds connect/accept or join
(https://www.open-mpi.org/doc/v1.8/man3/MPI_Comm_join.3.php) and then
you should be able to take advantage of the RMA. At least, that is
what is written in the book ...

The One-Sided Communications from the Chapter 11 of the MPI standard?
For processes on the same node you might want to look at
MPI_WIN_ALLOCATE_SHARED.

Is there a way to import/map memory from a process (data acquisition) such that
an MPI program could 'take' or see that memory?
We have a need to do data acquisition at the rate of .7TB/s and need todo some
shuffles/computation on these data, some of the nodes are directly connected
to the
