摘要： Systems, methods, and storage media for using the otherwise-unutilized storage space on a storage device without having a substantial effect on the normal operation of the storage device by one or more users accessing the storage device through one or more primary file organization architecture controllers of the storage device are disclosed. Implementations may: identify, by a secondary file organization architecture controller, logical units of separation present on the virtual storage device without affecting operation of the primary file organization architecture of the computer; identify unutilized storage space on at least one of the logical units of separation; cause auxiliary data to be stored store in the unutilized storage space; record, in a data storage associated with the secondary file organization architecture, the state of the auxiliary data without notifying the primary file organization architecture controller; and retrieve at least some of the auxiliary data without notifying the file organization architecture controller.

摘要： Systems and methods are provided for specifying regional information such as a source and nature of a recommend viewport and a priority among multiple recommended viewports. Virtual reality video data can represent a 360-degree view of a virtual environment. In various examples, a region of the virtual reality video data can be determined, where the region includes a sub-section of the 360-degree view. A data structure can be generated for the region, where the data structure includes parameters that describe the region. The parameters can include a source associated with the region. The virtual reality video data and the data structure can be stored in a file.

摘要： A simultaneous multithread (SMT) processor having a shared dispatch pipeline includes a first circuit that detects a cache miss thread. A second circuit determines a first cache hierarchy level at which the detected cache miss occurred. A third circuit determines a Next To Complete (NTC) group in the thread and a plurality of additional groups (X) in the thread. The additional groups (X) are dynamically configured based on the detected cache miss. A fourth circuit determines whether any groups in the thread are younger than the determined NTC group and the plurality of additional groups (X), and flushes all the determined younger groups from the cache miss thread.

摘要： Providing memory bandwidth compression using compression indicator (CI) hint directories in a central processing unit (CPU)-based system is disclosed. In this regard, a compressed memory controller provides a CI hint directory comprising a plurality of CI hint directory entries, each providing a plurality of CI hints. The compressed memory controller is configured to receive a memory read request comprising a physical address of a memory line, and initiate a memory read transaction comprising a requested read length value. The compressed memory controller is further configured to, in parallel with initiating the memory read transaction, determine whether the physical address corresponds to a CI hint directory entry in the CI hint directory. If so, the compressed memory controller reads a CI hint from the CI hint directory entry of the CI hint directory, and modifies the requested read length value of the memory read transaction based on the CI hint.

摘要： The disclosed computer-implemented method for provisioning frequently used image segments from caches may include (1) storing a representation and a use counter for an image segment that is hosted on a storage system in a list of representations and use counters for image segments hosted on the storage system, (2) incrementing a current value of the use counter for the image segment in the list of representations and use counters each time the image segment is provisioned from the storage system, (3) determining that the current value of the use counter for the image segment has met a predetermined threshold for frequent image-segment provisioning, (4) hosting the image segment in a cache that enables quicker provisioning than the storage system enables, and (5) provisioning the image segment from the cache in response to a request to provision the image segment. Various other methods, systems, and computer-readable media are also disclosed.

摘要： One embodiment of the present invention provides a system for efficiently warming up a cache. During operation, the system determines a cache prediction based on a user request. The cache prediction determines replication data from a database; the replication data is data that is to be replicated in the cache from the database for warming up the cache. The system generates a control signal comprising a replication proportion, which determines the volume of the replication data, for the replication model. The system then stores the replication data prior to receiving a request for the replication data, thereby warming up the cache with the replication data.
