Transactional memory provides a means to bridge the discrepancy between programmer productivity and the difficulty in exploiting thread-level parallelism gains offered by emerging chip multiprocessors. Because the hardware has outpaced the software, there are very few modern multithreaded benchmarks available and even fewer for transactional memory researchers. This hurdle must be overcome for transactional memory research to mature and to gain widespread acceptance. Currently, for performance evaluations, most researchers rely on manually converted lock-based multithreaded workloads or the small group of programs written explicitly for transactional memory.
