AbstractTransactional Memory (TM) has been proposed as an alternative concurrency mechanism for the shared memory parallel programming model. Its main goal is to make parallel programming for Chip Multiprocessors (CMPs) easier than using the traditional lock synchronization constructs, without compromising the performance and the scalability.

This topic has received substantial research attention and several TM designs have been proposed using various TM benchmarks. We believe that the evaluation of TM proposals would be more solid if it included realistic applications, that address on-going TM research issues, and that provide the potential for straightforward comparison against locks.

In this paper, we introduce RMS-TM, a Transactional Memory benchmark suite composed of seven real-world applications from the Recognition, Mining and Synthesis (RMS) domain. In addition to featuring current TM research issues such as nesting and I/O and system calls inside transactions, the RMS-TM applications also provide a mix of short and long transactions with small/large read and write sets with low/medium/high contention rates. These characteristics, as well as providing lock-based versions of the applications, make RMS-TM a useful TM tool. Current TM benchmarks do not explore all these features. In our evaluation with selected STM and HTM systems, we nd that our benchmark suite is also scalable, which is useful for evaluating TM designs on high core counts.
