    Buzzword: Transputer.
    Mainframe era buzzword: frontend computer.

    ie: You run the operating system on the 'main' (OK,
    the right word is central) computer. Then the OS
    runs the app(s) on the other CPU+RAM boards on the

    - 1 Pentium 166 + 128M + loads of disks + network
    - 3 PCI cards with single PII/400 (or a specialized
    DSP for that matter) and 32 MB RAM.

    Then the programs need to be split up in 'small' parts
    and the OSes can give each fast CPU a task to chew on.

    Somewhat like the push equivalent of :)
