    Abstract: A method for evaluating objects in a data structure is provided. The method includes assigning one or more objects to one or more nodes in a data structure having at least a root node, in which the objects are assigned to the nodes in accordance with a first order to maintain pre-existing dependencies between the objects and to allow the objects to be evaluated in a serial manner to avoid deadlock when concurrently executing threads to evaluate the objects, and selecting a first object for evaluation, in response to determining that the current object is unevaluated.

    Abstract translation: 提供了一种用于评估数据结构中的对象的方法。 该方法包括将一个或多个对象分配给具有至少根节点的数据结构中的一个或多个节点，其中根据第一顺序将对象分配给节点，以保持对象之间的预先存在的依赖关系，以及 允许以串行方式评估对象，以在同时执行线程以评估对象时选择第一对象以进行评估，以响应于确定当前对象未被评估而避免死锁。

    Abstract: A compiler or runt-time system may determine a prefetch point to insert an instruction in order to prefetch a memory location and thereby reduce latency in accessing information from a cache. A prefetch predictor generator may decide where and whether to insert the appropriate instructions by looking at information from a hardware monitor. For example, information about cache misses may be analyzed. The differences between target addresses of those cache misses for different instructions may be determined. This information may also be used to determine the locations in the program where the prefetch instructions should be placed, as well as to calculate the address of the memory location being prefetched.

    Abstract translation: 编译器或runt-time系统可以确定预取点来插入指令以便预取存储器位置，从而减少从高速缓存访​​问信息的延迟。 预取预测器发生器可以通过查看来自硬件监视器的信息来决定何处以及是否插入适当的指令。 例如，可以分析关于高速缓存未命中的信息。 可以确定不同指令的那些高速缓存未命中的目标地址之间的差异。 该信息还可以用于确定应该放置预取指令的程序中的位置，以及计算正在预取的存储器位置的地址。
