Integrating Transactional Memory into C + +

We discuss the integration of transactional memory into the C++ programming language. We take a decidedly pragmatic approach in this paper: Our goal is to induce minimal changes consistent with implementability, usable transactional semantics, and the prevalent styles of C++ programs. In particular, we want to avoid designing a new language; rather, we want to enable incremental adoption of transactional memory into existing C++ code bases. The contribution of this paper is a careful analysis of the options rather than a final solution. In some cases, reasonable alternatives exist and experience in implementation and use must guide the final choice.
