STMBench7

Software transactional memory (STM) is a promising technique for controlling concurrency in modern multi-processor architectures. STM aims to be more scalable than explicit coarse-grained locking and easier to use than fine-grained locking. However, STM implementations have yet to demonstrate that their runtime overheads are acceptable. To date, empiric evaluations of these implementations have suffered from the lack of realistic benchmarks. Measuring performance of an STM in an overly simplified setting can be at best uninformative and at worst misleading as it may steer researchers to try to optimize irrelevant aspects of their implementations.
