Right, but I do need to use the hosts key to get control of where the processes are spawned. Any clue?

Looks like it is related to the hosts key. Works without that.

Hi folks!
I've been facing an issue with MPI_Comm_spawn_multiple when all the
following conditions are met:
1. 'count' is > 1
2. Any value of 'array_of_maxprocs' is > 1
3. Setting the "hosts" info key
What I'm finding is that the spawned processes hang at MPI_Init. Find
attached a test case. You can reproduce my issue with -np 1.
Is there anything I'm doing wrong? I'm using MPICH master at 1e6c4d8. I
haven't found a pending ticket, xfail test, or test case covering this
situation.
All the best,
Toni
