    • Method and system for address routing in a distributed computing system, such as a distributed computing system that uses PCI Express protocol to communicate over an I/O fabric. A destination identifier is provided to identify a physical or virtual host or end point. When a physical or virtual host or end point receives a PCI data packet it compares a list of source identifiers with destination identifiers to determine if a source identifier included in the transaction packet is associated with a destination identifier included in the transaction packet to determine if the transaction packet has a valid association. If the transaction packet has a valid association, it is routed to the target device. The present invention enables each host that attaches to PCI bridges or switches and shares a set of common PCI devices to have its own PCI 64-bit address space and enables the routing of PCI transaction packets between multiple hosts and adapters, through a PCI switched-fabric bus using a destination identifier.
    • 分布式计算系统中的地址路由方法和系统,例如使用PCI Express协议通过I / O架构进行通信的分布式计算系统。 提供目的地标识符以标识物理或虚拟主机或终点。 当物理或虚拟主机或终点接收到PCI数据分组时,将源标识符的列表与目的地标识符进行比较,以确定包括在事务分组中的源标识符是否与包括在事务分组中的目的地标识符相关联,以确定是否 事务包具有有效的关联。 如果事务包具有有效关联,则将其路由到目标设备。 本发明使得连接到PCI桥接器或交换机并且共享一组公共PCI设备的每个主机能够具有其自己的PCI 64位地址空间,并且能够通过PCI交换机地址在多个主机和适配器之间路由PCI事务包, Fabric总线使用目的地标识符。

    • A computer program product for initiating a task in a computer system including executing a method that includes receiving a task and a status of the task relative to a target service level. A current power state of the processor is determined. Execution of the task is initiated on the processor in response to the status indicating that the task is meeting the target service level and to the current power state being a low power state. It is determined if the processor can be moved into a high power state, the determining performed if the task is not meeting the target service level and the current power state is the low power state. If the processor can be moved into the high power state then the processor is moved into the high power state and execution of the task is initiated on the processor.
    • 一种用于在计算机系统中启动任务的计算机程序产品,包括执行包括相对于目标服务级别接收任务和所述任务的状态的方法。 确定处理器的当前电源状态。 响应于指示任务满足目标服务级别的状态和处于低功率状态的当前功率状态,在处理器上启动任务的执行。 确定处理器是否可以移动到高功率状态,如果任务不满足目标服务水平并且当前功率状态是低功率状态,则执行确定。 如果处理器可以移动到高功率状态,则处理器移动到高功率状态,并且在处理器上启动任务的执行。
