a supercomputer is cluster of machines connected by high throughput, low latency interconnect.
Hundreds of servers connected together with 1Gigabit is still a "grid cluster" .. you need at least 10Gigabit Ethernet (over iWARP) or infiniband (RDMA) to be considered a supercomputer.
This is marketing B.S.! this B.S. is "emphasized" by the 90GFLOPS = 45Ghz thing. 90GFLOPS is by a single 45GHz "ALU" (perhaps an ALU doing Multiply-Add - MADD op.) not a full fledged CPU (like the i7 or Xeon, which has 4-8 cores with each core having 3 ALU's) as the readers might imply.

For example the i7 3770K does 121.6GFLOPS @ "only" 3.5Ghz (ref> table page 2 http://elrond.informatik.tu-freiberg.de/papers/WorldComp2012...)
measuring performance with Ghz is soooo Penitum III! the whole thing is very misleading, and I don't like that!
Supercomputer? not even funny! Its a Super-"Raspberry Pi". That's it!
