Abstract:
Software Transactional Memory (STM) was introduced as a promising technology to handle memory conflicts in parallel computing. In this paper, a performance comparison of various STM engine implementations is presented. The well-known Lee's algorithm was used for benchmarking ten different Scala based STM API variants, and one written in Kotlin. Results compare how these implementations scale in terms of the number of processor cores available and how they perform in terms of running time, compared to each other and a single threaded baseline implementation.
