Hybrid Transactional Memory(HyTM) has recently gained much interest because it combines the advantages of Hardware Transactional Memory(HTM) and Software Transactional Memory(STM). However, the existing HyTM schemes show good performance only for a specific workload. To solve this problem, we propose an adaptive HyTM scheme as efficient synchronization mechanism for multi-core environment. Our HyTM scheme can select its optimal fallback path by using a comprehensive TM coordinator, based on the characteristics of transactions. Finally, we show from our performance analysis using STAMP benchmark that our adaptive HyTM scheme can achieve about 130~160% better performance than the state-of-the-art HyTM ones, i.e., Hybrid NOrec and RH-NOrec.
