On hardware transactional memory systems, false sharing on the shared cache brings conflicts between some transactions even if the transactions do not share any data. This paper proposes a method for managing transaction conflicts not on each cache block but on each octet or such a small unit. The method can be implemented with low hardware costs, and the evaluation results show that the method can improve the performance of transactional memory 89.4% in maximum, and 26.3% in average.
