Adaptive Model-based Scheduling in Software Transactional Memory
Software Transactional Memory (STM) stands as powerful concurrent programming paradigm, enabling atomicity and isolation while accessing shared data. On the downside, STM may suffer from performance degradation due to excessive conflicts among concurrent transactions, which cause waste of CPU-cycles and energy because of transaction aborts. An approach to cope with this issue consists of putting in place smart scheduling strategies which temporarily suspend the execution of some transaction in order to reduce the transaction conflict rate.
