I tried "nodes=1" (my vbox machine has only one cpu), got the mom to

You are correct in that you should use the nodes=X syntax. I wonder how
meaningful your NUMA test can be for a node that has only one cpu and one
NUMA node, but that is a separate concern. I'm sorry the docs haven't been
updated yet, I will get that updated ASAP.

I'm surprised you're having trouble getting the mom to connect to the
server. What are the errors you're getting here?

This can't have anything to do with the mom.layout file. TORQUE does not
edit the permissions of these directories, it just attempts to access them.
What was the error?
