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