In computer science, a bridging model is an abstract model of a computer which provides a conceptual bridge between the physical implementation of the machine and the abstraction available to a programmer of that machine; in other words, it is intended to provide a common level of understanding between hardware and software engineers.
A successful bridging model is one which can be efficiently implemented in reality and efficiently targeted by programmers; in particular, it should be possible for a compiler to produce good code from a typical high-level language. The term was introduced by Leslie Valiant's 1990 paper A Bridging Model for Parallel Computation, which argued that the strength of the von Neumann model was largely responsible for the success of computing as a whole. The paper goes on to develop the bulk synchronous parallel model as an analogous model for parallel computing.
Famous quotes containing the words bridging and/or model:
“When its errands are noble and adequate, a steamboat bridging the Atlantic between Old and New England, and arriving at its ports with the punctuality of a planet, is a step of man into harmony with nature.”
—Ralph Waldo Emerson (1803–1882)
“Your home is regarded as a model home, your life as a model life. But all this splendor, and you along with it ... it’s just as though it were built upon a shifting quagmire. A moment may come, a word can be spoken, and both you and all this splendor will collapse.”
—Henrik Ibsen (1828–1906)
