Consistency Models1 David Mosberger TR 93/11 Abstract This paper discusses memory consistency models and their influence on software in the context of parallel machines. In the first part we review previous work on memory consistency models. The second part discusses the issues that arise due to weakening memory consistency. We are especially interested in the influence that weakened consistency models have on language‚ compiler‚ and runtime system design. We conclude that tighter interaction between

approach advanced by Gigerenzer and others. We make a proposal of how to integrate Simon‟s approach with the main current approaches to decision making. We argue that this would lead to better models of decision making that are more generalizable‚ have higher ecological validity‚ include specification of cognitive processes‚ and provide a better understanding of the interaction between the characteristics of the cognitive system and the contingencies of
