  • Patent number: 10887392
    Abstract: A method and system of storing and retrieving data in a computer system are disclosed. In an embodiment, the method comprises storing a data object at a specified location in a first data store, storing in a second data store first information identifying said specified location, retrieving the data object from a defined location in the first data store, obtaining second information identifying the defined location in the first data store, and comparing the second information to the first information to determine if the first information and the second information identify a same location in the first data store. In embodiments of the invention, the method further comprises when the second information and the first information identify different locations in the first data store, generating a fault signal to indicate that the location of the data object in the first data store has changed.

  • Patent number: 10324694
    Abstract: Mechanisms are provided for arranging binary code to reduce instruction cache conflict misses. These mechanisms generate a call graph of a portion of code. Nodes and edges in the call graph are weighted to generate a weighted call graph. The weighted call graph is then partitioned according to the weights, affinities between nodes of the call graph, and the size of cache lines in an instruction cache of the data processing system, so that binary code associated with one or more subsets of nodes in the call graph are combined into individual cache lines based on the partitioning. The binary code corresponding to the partitioned call graph is then output for execution in a computing device.

  • Patent number: 9727241
    Abstract: A processor maintains a count of accesses to each memory page. When the accesses to a memory page exceed a threshold amount for that memory page, the processor sets an indicator for the page. Based on the indicators for the memory pages, the processor manages data at one or more levels of the processor's memory hierarchy.

  • Patent number: 9696996
    Abstract: Mechanisms for extracting data dependencies during runtime are provided. With these mechanisms, a portion of code having a loop is executed. A first parallel execution group is generated for the loop, the group comprising a subset of iterations of the loop less than a total number of iterations of the loop. The first parallel execution group is executed by executing each iteration in parallel. Store data for iterations are stored in corresponding store caches of the processor, Dependency checking logic of the processor determines, for each iteration, whether the iteration has a data dependence. Only the store data for stores where there was no data dependence determined are committed to memory.
