Cris' output is coming solely from the HNP, which is correct given the way things were executed. My comment was from another email where he did what I asked, which was to include the flags:
--report-bindings --leave-session-attached so we could see the output from each orted. In that email, it was clear that while mpirun was bound to multiple cores, the orteds are being bound to a -single- core. Hence the problem.
