How I distinguish "supercomputer" and "mainframe":
- A mainframe is throughput oriented, a supercomputer more oriented to high
  speed on one particular job.
- A mainframe usually has a greater variety of I/O channels, larger disks,
  disk farm.
- A mainframe is more oriented towards transaction processing, database 
  querying.

Thus, a mainframe is intermediate between a (highly computationally oriented)
supercomputer, and a (I/O oriented) database machine.
