Some Terminology - 3

Metaproblem - Term describes a class of problem which is outside the

scope of a single computer architectures, but is instead best run on a

Metacomputer . These problems consist of many constituent subproblems.

Ex. the design and manufacture of a modern aircraft, which presents

problems in geometry grid generation, fluid flow, acoustics, structural

analysis, operational research, visualisation, and database management.

The Metacomputer for such a Metaproblem would be networked

workstations, array processors, vector supercomputers, MPP, and

visualisation engines.

Protocol - A set of conventions and implementation methodologies defining

the communication between nodes on a network. Ex. seven layer OSI

standard model going from physical link (optical fiber to satellite) to

application layer (such as Fortran subroutine calls).
