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. Susan.
