The present disclosure generally relates to prefetching data from one or more CPUs prior to the data being requested by a host device. The prefetched data is prefetched from memory and stored in cache. If a host device requests data that is not already in cache, then a determination is made regarding whether the data is scheduled to be written into cache. If the data is not in cache and is not scheduled to be written into cache, then the data is retrieved from memory and delivered to the host device. If the data is scheduled to be written into cache, or is currently being written into cache, then the request to retrieve the data is delayed or scheduled to retrieve the data once the data is in cache. If the data is already in cache, the data is delivered to the host device.

Calculating the optimal number of LBNs to prefetch per CPU

A method utilizes event-driven reoptimization to reallocate one or more logical partitions within a pool of logically-partitioned data processing systems in a logically-partitioned computing environment in response to detection of a system event that is likely to increase or decrease the collective resource demands of logical partitions resident in a logically-partitioned computing environment. The reoptimization may be used to consolidate logical partitions on fewer processor nodes to improve the potential for powering down hardware resources and thereby reduce power consumption.

The present disclosure generally relates to a method and system for efficiently sharing limited memory among multiple processors. Each processor has a local linked list. The local linked list identifies the pages allocated to the specific processor as well as the number of free codewords for each allocated page. Additionally, the local linked list includes the location of the next free codeword(s) for each allocated page. When all codewords are available, the page is considered free and may be sent back to the page pool used by all of the processors. If there are a sufficient number of contiguous free codewords on an allocated page, then new codeword data may be stored in the page. If there is not a sufficient number of contiguous free codewords on any allocated page, then a new page is allocated from the page pool. Thus, efficient allocate of memory resources is achieved.

Allocating shared memory among multiple tasks in a multiprocessor environment

A method and apparatus are provided for implementing reduced video stream bandwidth requirements when remotely rendering a complex computer graphics scene. Complexity of a scene is reduced at a server, prior to rendering a video stream that comprises the scene and transmitting the video stream to a client. Reducing the complexity of a scene at the server includes adjusting predefined scene configuration parameters. The order and degree to which predefined scene configuration parameters are adjusted is based upon a required stream bandwidth reduction to be made.

Methods and systems to obtain desired web content for a mobile device are disclosed. Users access web pages with mobile devices such as smart phones in addition to their non-mobile devices. In order to conveniently display information on mobile devices having smaller screens, mobile versions of web pages offering abridged content are available as well as non-mobile versions. When a web page is selected from search results provided from a query in a web search, the mobile or non-mobile versions of the web page may be delivered. By delivering a web page version to a mobile device based on relevance rankings determined for the non-mobile and mobile versions of the web page, desired content is more efficiently delivered. In this manner, a search experience may be improved by reducing deliveries of mobile versions of web pages to mobile devices where an alternative non-mobile version of the web page is preferred.

Obtaining desired web content from a mobile device

The invention addresses these and other problems associated with the prior art by providing an apparatus and program product that utilize event-driven reoptimization to reallocate one or more logical partitions within a pool of logically-partitioned data processing systems in response to detection of a system event that is likely to increase or decrease the collective resource demands of logical partitions resident in a logically-partitioned computing environment. In some instances, for example, the reoptimization may be used to consolidate logical partitions on fewer processor nodes to improve the potential for powering down hardware resources and thereby reduce power consumption.

System, method, and computer program product to present differences between a plurality of different media formats of a single media title, by presenting the media title in a first media format, of the plurality of different media formats, monitoring a progress of the presentation of the media title in the first format, identifying a first difference between the first media format and a second media format, of the plurality of different media formats of the media title, and providing an indication of the first difference based on the progress of the presentation of the media title in the first media format.

Method, computer program product, and system for identifying, responsive to a request for a network resource, at least one peer device, wherein the request is made by a first device on a mobile network, the at least one peer device on a local network with the first device, the local network different than the mobile network; partitioning, based on at least one content element of the requested network resource, the request into a plurality of subrequests, each subrequest specifying to retrieve one or more content elements of the requested network resource; assigning each subrequest to one of the peer devices and the first device, wherein each peer device and the first device retrieves the content elements specified by the subrequest assigned to the respective device, wherein each peer device transmits the retrieved portion of the network resource to the first device over the local network.

Method for improving mobile network performance via ad-hoc peer-to-peer request partitioning

Techniques are disclosed for managing deployment conflicts between applications executing in one or more processing environments. A first application is executed in a first processing environment and responsive to a request to execute the first application. During execution of the first application, a determination is made to redeploy the first application for execution partially in time on a second processing environment providing a higher capability than the first processing environment in terms of at least a first resource type. A deployment conflict is detected between the first application and at least a second application.

Detecting deployment conflicts in heterogeneous environments

System, method, and computer program product to identify differences between different media formats of a media title, by identifying at least one component of each of the different media formats of the media title, the at least one component comprising a unit of the media title, annotating a respective text transcription of each of the different media formats of the media title to include at least one attribute of the respective at least one component, computing a difference score for a first component of a first media format of the media title relative to each of the remaining different media formats of the media title, and upon determining that the difference score for the first component relative to a second media format of the media title exceeds a predefined threshold, creating an indication that the first component of the first media format is different from the second media format.
