A transactional memory simplifies the concurrency management in multicore systems by permitting sets of load and store instructions to be executed in an atomic way. The correct results for concurrent transactions and the execution time strongly depend on the coherency potentials, rollback capabilities and strategies of the transactional memory. A transactional memory can be implemented as a Har...

We present an analytical performance modeling approach for concurrency control algorithms in the context of Software Transactional Memories (STMs). Unlike existing approaches, we consider a realistic execution pattern where each thread alternates the execution of transactional and non-transactional code portions. Also, our model captures dynamics related to the execution of both transactional r...
