Link utilization will be low when there isn't a lot of communication
going on between cores -- e.g. when there isn't a lot of sharing and the
working sets fit in the private caches. Select a workload with a bigger
working set or more communication, or both.

I find in my ruby statistics that the link utilization is too low just about 0.03
flit/cycle using utraIII+. When i use opal, the link utilization increased about 2
times almost to 0.06 which is still too low. Any one can tell me why? or how can i
increase the link utilization? By the way, i want to know the probable link
utilization when the network saturates, for example 2D-mesh.
