Patent abstract

One embodiment of the present invention provides a system that facilitates load reordering through cacheline marking. During operation, the system receives a load operation to be executed. Next, the system determines whether a cacheline for the load has been load-marked by a thread which is performing the load. If so, the system performs the load. Otherwise, the system obtains the cacheline and subsequently attempts to load-mark the cacheline. If the cacheline is successfully load-marked, the system performs the load.
