Abstract

Hardware Transactional Memory (HTM) implementations are becoming available in commercial, off-the-shelf components. While generally comparable, some implementations deviate from the strict all-or-nothing property of pure Transactional Memory. We analyse these deviations and find that with small modifications, they can be used to accelerate and simplify both transactional and non-transactional programming constructs. At the heart of our extensions we enable access to the transaction's full register state in the abort handler in an existing HTM without extending the architectural register state. Access to the full register state enables applications in both transactional and non-transactional parallel programming: hybrid transactional memory; transactional escape actions; transactional suspend/resume; and alert-on-update.
