I don’t know why/how it got dropped from the man page, but the display-map 
option certainly still exists - do “mpirun -h” to see the full list of options, 
and you’ll see it is there. I’ll ensure it gets restored to the man page in the 
1.10 series as the 1.8 series is complete.

That’s a tough one. I’m not sure there is a way to do that right now. Probably 
something we’d have to add. Out of curiosity, if you have 4 sockets and only 2 
procs, would you want each proc bound to 2 of the 4 sockets? Or are you 
expecting them to be bound to only 1 socket (thus leaving 2 sockets idle), or 
simply leave them unbound?

Definitely no way to do this one today.
