In computer science , a bridging model is an abstract model of a computer qui Provides a conceptual bridge entre les physical implementation of the machines and the abstraction available to a program 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 implemented in reality and is targeted by programmers; in particular, it should be possible to compile 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 argues that the strength of the Neumann model is 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 .
