摘要
Mechanisms are provided for handling conflicts in a transactional memory system. The mechanisms execute threads in a data processing system in a first conflict resolution mode of operation in which threads execute conflicting transactional blocks speculatively. The mechanisms determine, for a transactional block, if the first conflict resolution mode of operation is to be transitioned to a second conflict resolution mode of operation in which threads accessing conflicting transactional blocks are executed serially and non-speculatively. Moreover, the mechanisms execute a thread that accesses the transactional block using the second conflict resolution mode of operation in response to the determination indicating that the first conflict resolution mode of operation is to be transitioned to the second conflict resolution mode of operation.
