KELLY 2

• One thousand processors
• Each processor is a ``commodity'' microprocessor (i.e. very cheap), with peak performance 100 MFLOP
• Useful computation requires communication between processors
  • Could exchange 1TByte tapes by Royal Mail (first class)

    1TByte/day 10MByte/s

    Any-to-any: everyone could send to same processor at same time, or vice versa (?)
