Shared memory abstraction on distributed memory hardware has become very popular recently. The abstraction can be provided at various levels in the architecture e.g. hardware, software, employing special mechanisms to maintain coherence of data. In this paper we present a survey of basic techniques and review a large number of architectures that provide such an abstraction. We also propose new terminology which is more consistent and orderly as compared with the existing use of terminology for such architectures.
