Abstract: Systems, apparatuses, and methods for dynamically partitioning a memory cache among a plurality of agents are described. A system includes a plurality of agents, a communication fabric, a memory cache, and a lower-level memory. The partitioning of the memory cache for the active data streams of the agents is dynamically adjusted to reduce memory bandwidth and increase power savings across a wide range of applications. A memory cache driver monitors activations and characteristics of the data streams of the system. When a change is detected, the memory cache driver dynamically updates the memory cache allocation policy and quotas for the agents. The quotas specify how much of the memory cache each agent is allowed to use. The updates are communicated to the memory cache controller to enforce the new policy and enforce the new quotas for the various agents accessing the memory.

Abstract: Techniques for performing processing to recover metadata may include: shadow top structures, and performing processing that uses the shadow top structures to recover information for an index node associated with an object of a file system having a file system logical address space. One of the shadow top structures is created for each metadata (MD) top node of a MD mapping structure used to determine storage locations of data stored at corresponding logical addresses in the file system logical address space. Each MD top node is used in determining storage locations for a specified subrange of logical addresses of the file system logical address space. Each shadow top structure corresponding to a MD top node describes each file system object mapped to a logical address included in the specified subrange of logical addresses of the file system address space associated with the corresponding MD top node.

Abstract: A fixed-width pulse generator includes a metastability detector circuit, a delay signal generator, and a combinational logic circuit. The metastability detector circuit is configured to receive a trigger signal and generate state detection signals. The delay signal generator is configured to receive the state detection signals and the trigger signal, and delay the trigger signal by two different delay values to generate two different delayed signals. One of the delay values is based on the state detection signals. The combinational logic circuit is configured to receive the two delayed signals and an error signal, and generate a fixed-width pulse that remains constant over process, voltage, and temperature variations.

Abstract: An online system provides navigation information customized using travel preferences of users. The online system receives actions performed by users that may indicate their geographical locations of interest. The online system may use a model to predict a user's level of interest in destination geographical locations. The online system generates navigation information or travel information that describes routes from origin geographical locations of users to destination geographical locations to which the users are likely to travel. The online system transmits the navigation information to client devices for presentation as personalized or dynamically-created content items to users. The online system may generate navigation information using catalogs describing routes between geographical locations. For instance, the catalog indicates a vehicle for navigation along a route, as well as origin and destination geographical locations.

Abstract: A method for determining the significance of a document, or a portion thereof, is disclosed. Accordingly a search engine, or some other application, analyzes user associated content portions of a document to determine a relevance score for the document (e.g. Curation Rank). The particular algorithm for determining the relevance score will vary depending upon the particular implementation, but may generally be based upon an analysis of the number and quality of user associated content portions, comments, ratings of the user's themselves, and the ratings of users contributing to interactions (e.g. sharing) with the content portions. Based on this analysis, the document is assigned a relevance score which is used for ranking the document in accordance with instructions associated with a search query. E.g. the document relevance score may be used in selecting and ordering documents returned in search results for a particular search query.

Abstract: Features are disclosed for accurately authenticating a delivery agent for unattended delivery of an item. The systems and methods described confirm the location of the delivery agent and proximity to the delivery location using short range wireless communications between a monitoring device at the delivery location and a communication device associated with the delivery agent. Access may also be conditioned on user specified “do not disturb” rules indicating when remote access is authorized. The authentication may be dynamically assessed such as based on a type of item being delivered.
