Abstract—Conflict detection and resolution are among the most fundamental issues in transactional memory systems. Hardware transactional memory (HTM) systems such as AMD’s Advanced Synchronization Facility (ASF) employ in-herent cache coherence protocol messages to perform conflict detection among transactions. Such an implementation has the advantage of design simplicity, nonetheless, it also generates false transactional conflicts due to false sharing within cache lines, unnecessarily reducing the overall performance. In this work, we first investigated the behavior of false transactional conflicts under the AMD’s ASF system. It is found that false conflicts showed rather stable pattern within each cache line that subsequently inspired ou...
