About a tenth of our 1000-node cluster is Myrinet-connected, and these 
nodes are reserved for computational chemistry/molecular dynamics which 
are the largest cpu users on our system.

Ours is a mixed-use cluster -- bioinformatics is a large percentage of 
the total jobs, but a small percentage of the cpu cycles.
Then we have a large chunk of image-processing jobs, which also don't 
need Myrinet.
