Abstract: Managing connected data, such as a graph data store, includes a computing device with persistent memory and volatile memory. The computing device stores a graph data store with a plurality of nodes and edges in persistent memory. Each of the edges defines the relationship between at least two of the nodes. The nodes and edges may contain tags and properties containing additional information. In response to a search request query, the computing device generates an iterator object stored in volatile memory with a reference to one or more nodes and/or edges in the graph data store. The split between volatile and persistent memory allocation could be used for other objects, such as allocators and transactions. Other embodiments are described and claimed.

Abstract: In one embodiment, a predefined behavior of a virtual machine monitor (VMM) with respect to one or more virtual machines (VMs) is identified, and processor-managed resources associated with the one or more VMs are utilized based on the predefined behavior of the VMM.

Abstract: One embodiment of the present invention is a technique to invalidate entries in a translation lookaside buffer (TLB). A TLB in a processor has a plurality of TLB entries. Each TLB entry is associated with a virtual machine extension (VMX) tag word indicating if the associated TLB entry is invalidated according to a processor mode when an invalidation operation is performed. The processor mode is one of execution in a virtual machine (VM) and execution not in a virtual machine. The invalidation operation belongs to a non-empty set of invalidation operations composed of a union of (1) a possibly empty set of operations that invalidate a variable number of TLB entries, (2) a possibly empty set of operations that invalidate exactly one TLB entry, (3) a possibly empty set of operations that invalidate the plurality of TLB entries, (4) a possibly empty set of operations that enable and disable use of virtual memory, and (5) a possibly empty set of operations that configure physical address size, page size or other virtual memory system behavior in a manner that changes the manner in which a physical machine interprets the TLB entries.

Abstract translation: 本发明的一个实施例是使翻译后备缓冲器（TLB）中的条目无效的技术。 处理器中的TLB具有多个TLB条目。 当执行无效操作时，每个TLB条目与虚拟机扩展（VMX）标签字相关联，指示相关联的TLB条目是否根据处理器模式而无效。 处理器模式是虚拟机（VM）中的执行之一，而不是虚拟机中的执行。 无效操作属于一个无效的无效操作集合，它由（1）可能为空的操作集合组合，使一组可变数量的TLB条目无效，（2）一组可能的空白操作，使一个TLB无效 条目，（3）使多个TLB条目无效的可能的一组操作，（4）启用和禁用虚拟存储器的使用的可能的一组可能的空操作，以及（5）配置物理的可能的一组操作 地址大小，页面大小或其他虚拟内存系统行为，以改变物理机器解释TLB条目的方式。
