One of the key design points of any hardware transactionalmemory (HTM) system is the conflict detection mechanism, and its efficientimplementation becomes critical when conflicts are not a rare event.While many contemporary proposals rely on the coherence protocol tocarry out conflict detection at the private cache levels, this approachis not optimal for systems that use a directory to maintain coherenceover an unordered, scalable network, such as tiled CMPs. In this paper,we present a new scheme of conflict detection for HTM systems, whichmoves this key mechanism from the private caches to the directory level.We propose a novel transactional book-keeping method and describe howthis detection can be carried out more efficiently at the directory. Simulationresults show that our approach obtains reductions in execution timebetween 25 and 55% for transactional benchmarks with a high numberof conflicts, with an average improvement over LogTM-SE of 15%.
