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 ...

But this is within the same MPI "universe" right?

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 dev
