摘要： The maximum current is limited in a multi-processor core system by monitoring the latest power consumption in the processor cores, in order to prevent a system shutdown as a result of an over-current event. If the sum of the latest power of the processor cores exceeds a threshold limit, a performance state (P-state) limit is enforced in the processor cores. The P-state limit causes a P-state change to a lower frequency, voltage and thus a lower current.
摘要翻译：通过监控处理器核心中的最新功耗，多处理器核心系统中的最大电流受到限制，以防止由于过电流事件导致系统关闭。如果处理器核心的最新功率的总和超过阈值限制，则在处理器核心中执行性能状态（P状态）限制。 P态极限导致P态变化到较低的频率，电压，从而导致较低的电流。

摘要： A central processing unit (processor) having multiple cores and a method for controlling the performance of the processor. The processor includes a first storage location configured to store a first threshold associated with a first boost performance state (P-State). The processor also includes logic circuitry configured to increase performance of active processor cores when an inactive processor core count meets or exceeds the first threshold. The processor may also include a second storage location configured to store a second threshold associated with a second boost P-State.

摘要： Mitigating eviction of the memory pages of virtualized machines. Upon detecting that a request to perform an I/O operation has been issued against a block stored a disk, a determination is made as to whether a pristine copy of the contents of the block is stored in memory. If a pristine copy of the contents of the block is stored in memory, then the request may be performed by updating mapping data that maps a page of memory to a location in memory at which the pristine copy is stored. In this way, the request is performed without performing the I/O operation against the block stored on disk. Various approaches for resharing memory, including memory of a template virtual machine, are discussed.

摘要： Approaches for transferring data to a client by safely receiving the data in or more virtual machines. In response to the client determining that digital content, originating from an external source, is to be received or processed by the client, the client identifies, without human intervention, one or more virtual machines, executing or to be executed on the client, into which the digital content is to be stored. In doing so, the client may consult policy data to determine a placement policy, a containment policy, and a persistence policy for any virtual machine to receive the digital content. In this way, digital content, such as executable code or interpreted data, of unknown trustworthiness may be safely received by the client without the possibility of any malicious code therein from affecting any undesirable consequence upon the client.

摘要： Approaches for executing untrusted software on a client without compromising the client using micro-virtualization to execute untrusted software in isolated contexts. A template for instantiating a virtual machine on a client is identified in response to receiving a request to execute an application. After the template is identified, without human intervention, a virtual machine is instantiated, using the template, in which the application is to be executed. The template may be selected from a plurality of templates based on the nature of the request, as each template describe characteristics of a virtual machine suitable for a different type of activity. Selected resources such as files are displayed to the virtual machines according to user and organization policies and controls. When the client determines that the application has ceased to execute, the client ceases execution of the virtual machine without human intervention.

摘要： Approaches for synchronizing resources of a virtualized web browser. When a virtualized web browser is instructed to display a web page, a host module executing within a host operating instructs retrieves, from each of one or more virtual machines, contents for a portion of the web page. The virtualized web browser assembles the contents and displays the web page. A web browser executing in the host operating system may, but need not, retrieve any of the content displayed thereby. Instead, the content retrieved by the web browser executing in the host operating system may be retrieved by and rendered within a virtual machine. The behavior of the virtualized web browser may be configured using policy data.
