Executive Summary

Concurrent data structures are usually designed to satisfy correctness conditions such as sequential consistency and linearizability. In this paper, the authors consider the following fundamental question: what guarantees are provided by these conditions for client programs? They formally show that these conditions can be characterized in terms of observational refinement. Their study also provides a new understanding of sequential consistency and linearizability in terms of abstraction of dependency between computation steps of client programs.
