Some hadoop clusters are looking at/using infiniband - cluster network design depends on what sort of problems your dealing with.

Pretty sure everything in top500 is using infiniband by now.

I was briefly involved with the supercomputing world about four years ago. "Should we use Infiniband?" was no longer considered a non-rhetorical question even then.

It's either Infiniband or some other high speed interconnect. It's not exclusively Infiniband, for instance the Chinese developed their own, but it's usually something similar.

Without Infiniband or similar proprietary buses, it is usually not considered a supercomputer at all, but merely a cluster.

I think the lines between "Super Computer" and "High Performance Cluster" have become blurred.
