     452These parameters result in this packing, which fits in fewer nodes, but has the slight imbalances of splitting {{{lan-1}}} into 9 and 11 containers and {{{lan-2}}} into 4,5,and 6 container partitions.  Again, this asymmetry is an attempt to consider the internode networking costs.

     456If the packing constraints are exact - 11 containers on {{{lan-1}}} is unacceptable - a second choice is to use the {{{--nodes-only}}} option.  This sets the cost of each arc in the graph to 0.  Metis ignores such arcs altogether, so the partitions are completely even.  This may cause trouble in more complex network topologies.
