We always output the entire map, so you'll see the parent procs as
well as the child

Hi Ralph,
No I'm happy to get a map at the beginning and at every spawn. Do
you send the whole map again, or only an update?
Regards,
Greg

It already somewhat does. If you use --display-map at mpirun, you
automatically get display-map whenever MPI_Spawn is called.
We didn't provide a mechanism by which you could only display-map
for MPI_Spawn (and not for the original mpirun), but it would be
trivial to do so - just have to define an info-key for that
purpose. Is that what you need?

Ralph,
At the moment -display-map shows the process mapping when mpirun
first starts, but I'm wondering about processes created
dynamically. Would it be possible to trigger a map update when
MPI_Spawn is called?
Regards,
Greg
