Oh man, sorry about that, and thanks for the fast response.
Let me try again, please :)

I want to manually specify what ranks should run on what node.

Here is an example of a mapping that I can't seem to be able to do, since
it isn't a round-robin type of mapping.

hosts ranks
===========
node0 0,1,3
node1 2,4,5

No matter what I do, I either get

node0: 0,1,2
node1: 3,4,5

or

node0: 0,2,4
node1: 1,3,5

Hope I got it right this time, and thank you again.
