This book explores the problem of choosing a computation model for parallel computing. The author proposes choosing the model that permits the most computation in a given amount of time. Two main theorems are proven: the first asserts that for every exclusive-read exclusive-write parallel RAM or synchronous distributed machine, there exists a simulation of the Fetch-and-Add parallel RAM into the same machine that uses the same order of computational resources. This implies the choice of a Fetch-and-Add parallel RAM model of computation. The second theorem asserts that for every synchronous distributed machine, there exists a simulation of the exclusive-read exclusive-write parallel RAM into the same machine that uses the same order of computational resources. These findings further support the use of Fetch-and-Add primitives in parallel computation design.

Excerpt from On Choice of a Model of Parallel Computation
The present paper falls mainly within the following abstract scheme. Suppose that a model M of synchronous 97parallel computation that allows some operations in any cycle, but forbids others, is given. Assune, that it is possible to simulate every cycle of any algorithm in M, within certain resource requirements, into'some weaker model of computation D, that represents a technologically available machine. We are interested in the question: Is it possible to allow in cycles of M some of the forbidden operations and still get a simulation of each cycle into D, vithin about the same resource requirements?
The advantages of succeeding to give an affirmative answer to the above question are the following. Imagine that a programmer wrote programs for model M to be later translated by the (aforementioned) simlation into D. Now, the person has more powerful primitives in his programming language (the language describing model M). Therefore, we enable simpler and more efficient (in terms of composition of primitives) algorithms to be designed and programs to be written.
