ISSN 0362-1340. Vol. 48, N.º 8 (2013), pp. 303-304.0362-1340http://hdl.handle.net/10400.21/2836In this paper, we propose a new technique that can identify transaction-local memory (i.e. captured memory), in managed environments, while having a low runtime overhead. We implemented our proposal in a well known STM framework (Deuce) and we tested it in STMBench7 with two different STMs: TL2 and LSA. In both STMs the performance improved significantly (4 times and 2.6 times, respectively). Moreover, running the STAMP benchmarks with our approach shows improvements of 7 times in the best case for the Vacation application.engNeutrino physicsDiscrete and finite symmetries performanceTransactionsSoftware transactional memoryRuntime optimizationsjournal article10.1145/2517327.2442556
