摘要： A mechanism, method and computer usable medium is provided for each root node of a multiple root node system and its own independent address space. This mechanism also allows multiple system images within the same root node to have their own independent address spaces. A mechanism is also provided for incorporating legacy root node and input/output adapters that are non-aware of the mechanisms introduced by this invention. Input/ output adapters which implement this invention may also have the number of functions that they support greatly expanded beyond the present eight functions per input/output adapter.

摘要： A method and apparatus is provided for routing error messages in a distributed computer system comprising multiple root nodes, and further comprising one or more PCI switches and one or more I/O adapters, wherein each root node includes one or more system images. In one useful embodiment, a method is provided for routing I/O error messages to root nodes respectively associated with the errors contained in the messages. The method includes detecting occurrence of an error at a specified one of the adapters, wherein the error affects one of the system images, and generating an error message at the specified adapter. The method further comprises routing the error message from the specified adapter to the particular root node that includes the affected system image. The error message is then selectively processed at the particular root node, in order to identify the affected system image. Usefully, the step of routing the error message includes using a bus/device/function number associated with the error, together with a routing table located in one of the PCI switches, to route the error message to the correct root node and system image.

摘要： A method is directed to use of a master root node, in a distributed computer system provided with multiple root nodes, to control the configuration of routings through an I/O switched-fabric. One of the root nodes is designated as the master root node or PCI Configuration Manager (PCM), and is operable to carry out the configuration while each of the other root nodes remains in a quiescent or inactive state. In one useful embodiment pertaining to a system of the above type, that includes multiple root nodes, PCI switches, and PCI adapters available for sharing by different root nodes, a method is provided wherein the master root node is operated to configure routings through the PCI switches. Respective routings are configured between respective root nodes and the PCI adapters, wherein each of the configured routings corresponds to only one of the root nodes. A particular root node is enabled to access each of the PCI adapters that are included in any configured routing that corresponds to the particular root node. At the same time, the master root node writes into a particular root node only the configured routings that correspond to the particular root node. Thus, the particular root node is prevented from accessing an adapter that is not included in its corresponding routings.
摘要翻译：一种方法涉及在具有多个根节点的分布式计算机系统中使用主根节点来控制通过I / O交换结构的路由的配置。一个根节点被指定为主根节点或PCI配置管理器（PCM），并且可操作以在每个其他根节点保持处于静态或非活动状态的同时执行配置。在与上述类型的系统相关的一个有用的实施例中，其包括可用于不同根节点共享的多个根节点，PCI交换机和PCI适配器，提供了一种方法，其中主根节点被操作以配置通过PCI的路由开关。相应的路由被配置在相应的根节点和PCI适配器之间，其中每个配置的路由仅对应于根节点之一。特定根节点能够访问包含在与特定根节点对应的任何配置的路由中的每个PCI适配器。同时，主根节点将特定根节点只写入与特定根节点对应的已配置路由。因此，防止特定根节点访问未包括在其对应的路由中的适配器。

摘要： Virtual machine images are distributed to, and retrieved from an image distribution network. A virtual machine image is received on the image distribution network and divided into chunks with a unique resource identifier created for each of the chunks. A virtual machine image reassembly file is created. Each of the chunks is assigned a unique resource locator address. An image distribution network server maintains a mapping between unique resource identifier for each of the chunks and the unique resource locator address. When a request to download a virtual machine image is received, chunks of the virtual machine image that are locally present are identified. Chunks of the virtual machine image that are not locally present are mapped to unique resource locator addresses in the image distribution network. When a sufficient number of chunks has been retrieved to instantiate the virtual machine image, the virtual machine image is instantiated.

摘要： Mechanisms for performing all-to-all comparisons on architectures having limited storage space are provided. The mechanisms determine a number of data elements to be included in each set of data elements to be sent to each processing element of a data processing system, and perform a comparison operation on at least one set of data elements. The comparison operation comprises sending a first request to main memory for transfer of a first set of data elements into a local memory associated with the processing element and sending a second request to main memory for transfer of a second set of data elements into the local memory. A pair wise comparison computation of the all-to-all comparison of data elements operation is performed at approximately a same time as the second set of data elements is being transferred from main memory to the local memory.

摘要： A common infrastructure collects diverse data and information from large numbers of mobile devices and traditional sensors at Internet scale to support multiple different applications simultaneously. The infrastructure includes a backend phenomenon layer that provides high level abstractions to applications such that they can express their data and information needs in a declarative fashion and coordinate the data collection and processing activities for all applications. An edge layer that manages devices, receives collection requirements from the backend layer, configures and instructs devices for data collection, and conducts aggregation and primitive processing of the data. This layer contains network edge nodes, such as base stations in a cellular network. Each node manages a set of local data generating networked devices. The device agent data layer using common agents on the data generating networked devices receives data collection instructions from the edge layer, performs data collection.
