    Abstract: A method for resource management of a data processing system is described herein. According to one embodiment, a token is periodically pushed into a memory usage queue, where the token includes a timestamp indicating time entering the memory usage queue. The memory usage queue stores a plurality of memory page identifiers (IDs) identifying a plurality of memory pages currently allocated to a plurality of programs running within the data processing system. In response to a request to reduce memory usage, a token is popped from the memory usage queue. A timestamp of the popped token is then compared with current time to determine whether a memory usage reduction action should be performed.

    Abstract: The subject technology determines input parameters and an output format of algorithms for a particular functionality provided by an electronic device. The subject technology determines an order of the algorithms for performing the particular functionality based on temporal dependencies of the algorithms, and the input parameters and the output format of the algorithms. The subject technology generates a graph based on the order of the algorithms, the graph comprising a set of nodes corresponding to the algorithms, each node indicating a particular processor of the electronic device for executing an algorithm. Further, the subject technology executes the particular functionality based on performing a traversal of the graph, the traversal comprising a topological traversal of the set of nodes and the traversal being based on a score indicating whether selection of a particular node for execution over another node enables a greater number of processors to be utilized at a time.

    Abstract: Some embodiments can load one or more applications into working memory from persistent storage when permitted by a memory pressure level of a mobile device. Loading the applications into working memory enables the applications to be launched into the foreground quickly when the user indicates the desire to launch. Some embodiments may identify a set of applications that are designated for providing snapshots to be displayed when the mobile device is in a dock mode. Certain embodiments may determine a current memory pressure level. Some embodiments may load an application in the set of applications into working memory from a persistent storage responsive to determining that the memory pressure level is below a threshold. Certain embodiments may continue to load additional applications responsive to determining that the memory pressure level is below the threshold. After determining that the memory pressure level is above the threshold, some embodiments may reclaim memory.
