But all the supercomputers use their own custom linux. So no commerical backing. Also these computers are not your standard data center. They cut networking and storage to a minimal because those are bottlenecks. These things are just massive ram/cpu/gpu boxes connected properly through pci.
Edit: I was looking at Sunway hardware specs the number one supercomputer they use a PCI-E 3.0 connection for all there nodes. Communication between the nodes is 12GB/second with a latency of 1 us. Their total ram is 1.31 PB
