    • A technique for accessing a shared resource of a computerized system involves running a first portion of a first thread within the computerized system, the first portion (i) requesting a lock on the shared resource and (ii) directing the computerized system to make operations of a second thread visible in a correct order. The technique further involves making operations of the second thread visible in the correct order in response to the first portion of the first thread running within the computerized system, and running a second portion of the first thread within the computerized system to determine whether the first thread has obtained the lock on the shared resource. Such a technique alleviates the need for using a MEMBAR instruction in the second thread.
    • 用于访问计算机化系统的共享资源的技术包括运行计算机化系统内的第一线程的第一部分,第一部分(i)请求锁定共享资源,以及(ii)引导计算机化系统使 第二个线程以正确的顺序可见。 该技术还涉及使第二线程的操作响应于在计算机化系统内运行的第一线程的第一部分以正确的顺序可见,并且在计算机化系统内运行第一线程的第二部分以确定第一线程 已获得共享资源上的锁定。 这种技术减轻了在第二线程中使用MEMBAR指令的需要。
