An augmented reality (AR) effect system can improve application of AR effects by sharing resources between AR effects. The AR effect system can employ manifests for AR effects that define which resources are required to render each AR effect. The AR effect system can organize rendering operations used by selected AR effects into a pipeline and can use the manifests of the AR effects to determine when each resource will be needed. Based on this pipeline, the AR effect system can create a cache order defining a resource schedule which specifies, when a resource is freed, conditions for whether to save the resource to a local cache or unload the resource. As rendering of the video with the AR effects progresses, the resource schedule can control whether resources not currently being used to render an AR effect should be unloaded or cached for fast access for future render operations.

The method comprises, in a first generation step: reading a first engine logical timestamp vector of a first execution engine of the execution engines, the logical timestamp representing a history of access operations for the resource; determining whether the first engine logical timestamp vector includes a most-up-to-date logical timestamp of the resource in the first generation step; based on the first engine logical timestamp vector including the most-up-to-date logical timestamp of the resource in the first generation step, generating an access instruction to be executed by the first execution engine to access the resource; and scheduling the first execution engine to execute the access instruction.

A method, an information handling system (IHS) and a memory mirroring system for operating a mirrored memory. The method includes detecting, via a memory controller, at least one uncorrectable data error (UCDE) in a first memory device. In response to detecting the at least one UCDE, a UCDE event counter is retrieved that tracks the number of UCDE events that have occurred and a UCDE event threshold is retrieved corresponding to a maximum number of allowed UCDE events. The method further includes determining if the UCDE event counter is greater than the UCDE event threshold and in response to determining that the UCDE event counter is not greater than the UCDE event threshold, continuing writing of data to the first memory device via a first memory channel and continuing writing of the data to a second memory device via a second memory channel to create a mirror of the data.

A method and system for minimizing rolling database recovery downtime. Specifically, the disclosed method and system entail migrating and recovering database data from backup storage to local host storage while enabling database access operations through live mounts mapped to the database data on the backup storage. Database downtime may subsequently be reduced through the rapid switching of file system references between database data stored on backup storage and database data copies recovered on local storage.

Embodiments of the present disclosure relate to autonomous data protection. One or more input/output (I/O) streams can be received by one or more storage devices. One or more snapshots of each storage device can be obtained. One or more anomalies can be identified based on a change rate corresponding to each storage device's memory allocated to store user data included in the I/O streams.

A data center for data backup and replication, including a pool of multiple storage units for storing a journal of I/O write commands issued at respective times, wherein the journal spans a history window of a pre-specified time length, and a journal manager for dynamically allocating more storage units for storing the journal as the journal size increases, and for dynamically releasing storage units as the journal size decreases.

According to one embodiment, a magnetic disk device includes a magnetic disk, a storage unit, a magnetic head, an error correction unit that, in a case where an error is detected in user data read by the magnetic head, performs error correction on a sector in which the error is detected in track units and acquires error correction data, and a control unit. The control unit controls reading/writing of user data, management data for managing a sector on which the error correction is performed in the track units, and the error correction data, and in a case where there is no host access, rewrites data on the track including the sector on which the error correction is performed, based on the user data stored in the track and the error correction data of the sector, in which the error is detected, of the track.

A semiconductor device may include a memory bank and a plurality of mode registers that communicatively couple to each of the plurality of memory banks. The plurality of mode registers may include a pattern of data stored therein. The semiconductor device may also include a bank control that receives a write pattern command that causes the bank control to write the pattern of data into the memory bank, send a signal to a multiplexer to couple the plurality of mode registers to the memory bank, and write the pattern of data to the memory bank via the plurality of mode registers.
