Abstract: Systems and methods enable displaying a graphical representation of system resource usage in a resource utilization map to inform users about system resource utilization by applications and processes running on a computing device. Users may provide inputs to enable the system to adjust resource allocations based on user preferences. This may enable users to improve the overall operational performance of the device consistent with their current personal preferences by identifying applications or processes of most or least interest so the device processor to prioritize system resources accordingly. Some aspects transmit resource allocation data based on such user input to a central server to enable community based resource allocation schemes. Community based resource allocation schemes may be transmitted to computing devices for use as default or preliminary resource allocations for particular applications, websites or device operating states.

Abstract: Methods, servers, and systems for using signatures/certifications embedded in pre-processed code to enable use or reuse of pre-processed code to obviate the need to perform some operations or execute some scripts within the web page content. One or more operations may be performed within an executable script in web page content and signing the result of the operation in a manner that can be used to verify that the corresponding operation may be skipped by a browser. A browser receiving signed pre-processed code may use a signature verification process to determine whether the browser can bypass executing corresponding scripts in the web page content or perform alternative operations. Operations may be pre-performed and the results signed by off-line tools and included in the web page content. Results of operations may be stored in memory along with a signature so the results of the operation can be reused in the future.

Abstract: A solution for cooperative data prefetching that enables software control of a memory-side data prefetch and/or a processor-side data prefetch is provided. In one embodiment, the invention provides a solution for generating an application, in which access to application data for the application is improved (e.g., optimized) in program code for the application. In particular, a push request, for performing a memory-side data prefetch of the application data, and a prefetch request, for performing a processor-side data prefetch, are added to the program code. The memory-side data prefetch results in the application data being copied from a first data store to a second data store that is faster than the first data store while the processor-side data prefetch results in the application data being copied from the second data store to a third data store that is faster than the second data store.

Abstract: The various aspects provide methods, servers, and systems for identifying independent portions of an HTML document so that the identified portions may be processed in parallel. The independent portions may be associated with an iframe tag having both the seamless and sandbox attributes. At runtime, a browser may detect the presence of both attributes, and process the contents of the iframe in parallel.

Abstract: Methods and devices for accelerating webpage rendering by a browser store document object model (DOM) tree structures and computations of rendered pages, and compare portions of a DOM tree of pages being render to determining if portions of the DOM tree structures match. If a DOM tree of a webpage to be rendered matches a DOM tree stored in memory, the computations associated with the match DOM tree may be recalled from memory, obviating the need to perform the calculations to render the page. A tree isomorphism algorithm may be used to recognize DOM trees stored in memory that match the DOM tree of the webpage to be rendered. Reusing rendering computations may significantly reducing the time and resources required for rendering web pages. Identifying reusable portions of calculation results based on DOM tree isomorphism enables the browser to reuse stored webpage rendering calculations even when URLs do not match.

Abstract: The aspects include browser systems and methods of loading/rendering a webpage by processing the web document (HTML page) in parallel. A scanner process scans the web document, identifies scripts, and initiates the downloading of the scripts. As the scripts are downloaded, an HTML parser generates an identifier for each script and the sends the scripts and associated identifiers to a script engine. The script engine parses, analyzes, compiles, and otherwise prepares the scripts for execution in an order that may be different than the execution order of the scripts.

Abstract: A method of data processing in a processor includes maintaining a usage history indicating demand usage of prefetched data retrieved into cache memory. An amount of data to prefetch by a data prefetch request is selected based upon the usage history. The data prefetch request is transmitted to a memory hierarchy to prefetch the selected amount of data into cache memory.

Abstract: A method, a system and a computer program product for handling speculative stores. The system determines when a speculative store buffer is not full. An indicator is generated when the speculative store buffer is not full, and the speculative stores are input into the speculative store buffer. When the speculative store buffer is full, a full buffer indicator is generated. Speculative stores prevented from entering the speculative store buffer are overflow stores. The overflow list is searched to determine whether one or more addresses of the overflow stores are present in the overflow list. When one or more addresses of the overflow stores are not present in the overflow list, the overflow stores are stored in the overflow list.

Abstract: Mechanisms are provided for handling conflicts in a transactional memory system. The mechanisms execute threads in a data processing system in a first conflict resolution mode of operation in which threads execute conflicting transactional blocks speculatively. The mechanisms determine, for a transactional block, if the first conflict resolution mode of operation is to be transitioned to a second conflict resolution mode of operation in which threads accessing conflicting transactional blocks are executed serially and non-speculatively. Moreover, the mechanisms execute a thread that accesses the transactional block using the second conflict resolution mode of operation in response to the determination indicating that the first conflict resolution mode of operation is to be transitioned to the second conflict resolution mode of operation.

Abstract: Methods and devices for accelerating web page rendering include processing web pages and gathering web page element information, performing machine learning analysis on the gathered web page element information to identify patterns in layout independence correlated to web page element information, and training a classifier to predict sub-tree independence based on element information in a web page script. The predicted sub-tree independence may be used to concurrently process portions of a web page to be rendered to reduce the time required to render the page. Sub-trees may be conditionally independent, in which case, the conditionally independent sub-trees may be made independent by speculating data to render the sub-trees independent, or by performing a task to obtain the certain information to render the sub-tree independent.

Abstract: A method, system and computer program product for issuing one or more software initiated operations for creating a checkpoint of a register file and memory, and for restoring a register file and memory to the checkpointed state. At the execution of a checkpoint operation, the system returns a condition code indicating success or failure. When the condition code is set equal to one, one or more checkpoints are initiated. Contents of the register file and gated store buffer are stored each time the one or more checkpoints are initiated. When the checkpoint is created, the system notifies software when a hardware checkpoint capacity has been reached. One or more of the software checkpoint, hardware checkpoint, and handler checkpoint are utilized to provide a more precise point of restoration. During software execution, the register file and gated store buffer can be restored as defined by the one or more previous checkpoints.

Abstract: In at least one embodiment, a processor detects during execution of program code whether a load instruction within the program code is associated with a hint. In response to detecting that the load instruction is not associated with a hint, the processor retrieves a full cache line of data from the memory hierarchy into the processor in response to the load instruction. In response to detecting that the load instruction is associated with a hint, a processor retrieves a partial cache line of data into the processor from the memory hierarchy in response to the load instruction.

Abstract: Mechanisms are provided for performing performance monitoring of code executing in the data processing system. A performance measurement is obtained for the execution of a region of code of interest. A determination is made as to whether an overhead associated with a current performance measurement mechanism is greater than a predetermined threshold amount of the performance measurement for the execution of the region of code of interest. A dynamic switch is performed from the current performance measurement mechanism to a second performance measurement mechanism, having a lower overhead, for obtaining performance measurements for the execution of the region of code of interest in response to the overhead associated with the current performance measurement mechanism being greater than the predetermined threshold amount of the performance measurement for the execution of the region of code of interest.
