This paper presents OpenTM, an application programming interface (API) for parallel programming with transactions. OpenTM extends OpenMP, a widely used API for shared-memory parallel programming, with a set of compiler directives to express non-blocking synchronization and speculative parallelization based on memory transactions. We also present a portable OpenTM implementation that produces code for hardware, software, and hybrid TM systems. The implementation builds upon the OpenMP support in the GCC compiler and includes a runtime for the C programming language.
We evaluate the performance and programmability features of OpenTM. We show that it delivers the performance of fine-grain locks at the programming simplicity of coarsegrain locks. Compared to transactional programming with lower-level interfaces, it removes the burden of manual annotations for accesses to shared variables and enables easy changes of the scheduling and contention management policies. Overall, OpenTM provides a practical and efficient TM programming environment within the familiar scope of OpenMP.
