    • A method and apparatus for providing efficient strong atomicity is herein described. Optimized strong operations may be inserted at non-transactional read accesses to provide efficient strong atomicity. A global transaction value is copied at a beginning of a non-transational function to a local transaction value; essentially creating a local timestamp of the global transaction value. At a non-transactional memory access within the function, a counter value or version value is compared to the LTV to see if a transaction has started updating memory locations, or specifically the memory location accessed. If memory locations have not been updated by a transaction, execution is accelerated by avoiding a full set of slowpath strong atomic operations to ensure validity of data accessed. In contrast, the slowpath operations may be executed to resolve contention between a transactional and non-transaction access contending for the same memory location.
    • 这里描述了提供有效的强原子性的方法和装置。 可以在非事务性读访问中插入优化的强操作,以提供有效的强原子性。 全局事务值在非转换函数的开头被复制到本地事务值; 基本上创建了全局事务值的本地时间戳。 在功能内的非事务性存储器访问中,将计数器值或版本值与LTV进行比较,以查看事务是否开始更新存储器位置,或具体地访问存储器位置。 如果事务没有更新存储器位置,则通过避免一整套的慢路强原子操作来加速执行,以确保访问的数据的有效性。 相比之下,可以执行慢路操作来解决争用相同内存位置的事务和非事务访问之间的争用。

    • A method and apparatus for efficient and consistent validation/conflict detection in a Software Transactional Memory (STM) system is herein described. A version check barrier is inserted after a load to compare versions of loaded values before and after the load. In addition, a global timestamp (GTS) is utilized to track a latest committed transaction. Each transaction is associated with a local timestamp (LTS) initialized to the GTS value at the start of a transaction. As a transaction commits it updates the GTS to a new value and sets versions of modified locations to the new value. Pending transactions compare versions determined in read barriers to their LTS. If the version is greater than their LTS indicating another transaction has committed after the pending transaction started and initialized the LTS, then the pending transaction validates its read set to maintain efficient and consistent transactional execution.
    • 这里描述了用于在软件事务存储器(STM)系统中有效且一致的验证/冲突检测的方法和装置。 在加载之后插入版本检查障碍,以便在加载之前和之后比较加载值的版本。 此外,使用全局时间戳(GTS)来跟踪最近提交的事务。 每个事务与在事务开始时初始化为GTS值的本地时间戳(LTS)相关联。 作为事务提交,将GTS更新为新值,并将修改的位置的版本设置为新值。 待处理的交易将比较其在LTS阅读障碍中确定的版本。 如果版本大于其LTS,指示在挂起事务启动并初始化LTS之后另一个事务已经提交,则挂起的事务会验证其读取集合以保持有效且一致的事务执行。
