摘要： A method and apparatus for providing optimized strong atomicity operations for non-transactional writes is herein described. Locks are acquired upon initial non-transactional writes to memory locations. The locks are maintained until an event is detected resulting in the release of the locks. As a result, in the intermediary period between acquiring and releasing the locks, any subsequent writes to memory locations that are locked are accelerated through non-execution of lock acquire operations.

摘要： A method and apparatus for optimizing quiescence in a transactional memory system is herein described. Non-ordering transactions, such as read-only transactions, transactions that do not access non-transactional data, and write-buffering hardware transactions, are identified. Quiescence in weak atomicity software transactional memory (STM) systems is optimized through selective application of quiescence. As a result, transactions may be decoupled from dependency on quiescing/waiting on previous non-ordering transaction to increase parallelization and reduce inefficiency based on serialization of transactions.

摘要： A method and apparatus for optimizing weak atomicity overhead is herein described. A state table is maintained either during static or dynamic compilation of code to track data non-transactionally accessed. Within execution of a transaction, such as at transactional memory accesses or within a commit function, it is determined if data associated with memory access within the transaction is to be conflictingly accessed outside the transaction from the state table. If the data is not accessed outside the transaction, then the transaction potentially commits without weak atomicity safety mechanisms, such as privatization. Furthermore, even if data is accessed outside the transaction, optimized safety mechanisms may be performed to ensure isolation between the potentially conflicting accesses, while eliding the mechanisms for data not accessed outside the transaction.

摘要： A method and apparatus for dynamic optimization of strong atomicity barriers is herein described. During runtime compilation, code including non-transactional memory accesses that are to conflict with transactional memory accesses is patched to insert transactional barriers at the conflicting non-transactional memory accesses to ensure isolation and strong atomicity. However, barriers are omitted or removed from non-transactional memory accesses that do not conflict with transactional memory accesses to reduce barrier execution overhead.

摘要： According to one embodiment a computer method and apparatus for causing a computer to perform a speculative read re-ordered load is disclosed. A speculative read re-ordered load instruction is inserted into the instruction sequence to optimize the code. Memory conflict information representing the speculative read re-ordered load is stored. When a later potentially conflicting load is executed, its physical address is matched against the physical address of the stored memory conflict information. If the potentially conflicting load has a matching physical address and a different value than the stored memory conflict information representing the speculative read re-ordered load, then the stored memory conflict information is invalidated.
