A compute node can be a member of multiple partitions, this is how you can 
handle your case.

Suppose you have 4 nodes in part1 and 4 nodes in part2.  Then you can 
create a new partition "partbig" which contains all 8 nodes.

You may want to configure restrictions on "partbig" if you don't want 
every user to submit to it, or configure a lower maximum time for jobs.

I hope this helps,
