System and method for supporting node role attributes in a high performance computing environment. In accordance with an embodiment, a node role attribute can comprise a vendor defined subnet management attribute.

A processing device in a host system monitors a data temperature of a plurality of memory pages stored in a host-addressable region of a cache memory component operatively coupled with the host system. The processing device determines that a first memory page of the plurality of memory pages satisfies a first threshold criterion pertaining to the data temperature of the first memory page and sends a first migration command indicating the first memory page to a direct memory access (DMA) engine executing on a memory-mapped storage component operatively coupled with the cache memory component and with the memory-mapped storage component via a peripheral component interconnect express (PCIe) bus. The first migration command causes the DMA engine to initiate a first DMA transfer of the first memory page from the cache memory component to a host-addressable region of the memory-mapped storage component.

A computer-implemented technique controls consumption of applications by a supervisee (e.g., a child). The technique detects when a supervisee attempts to interact with an application. In response, the technique receives context input signals that describe a current context affecting the supervisee. The technique then generates an output result based on the current context information and a set of rules expressed by rule logic. The technique then controls interaction by the supervisee with the application based on the output result. In one implementation, the technique automatically generates the rule logic, which may correspond to a set of discrete rules and/or a machine-trained model that implicitly expresses the rules. At least some of the rules specify amounts of time allocated to the supervisee for interaction with the plural applications in plural contexts. According to another illustrative aspect, the technique uses a machine-trained model to automatically classify a new application.

Methods and systems for restoring data to a host device are described. According to some embodiments, a hybrid buffer may be used to generate a twin file of each file object to be restored and append the twin file to the corresponding file object. Each file object and its corresponding twin file may be transmitted to a construction container via a restore agent. In the event of an unexpected abort during the first restoration session, the restore agent may preserve the twin file of a file object currently being restored (if one has been created at the time of the abort) and instruct the hybrid buffer to terminate operation. During a subsequent restore session, the restore agent may poll for the preserved twin file and commence the data restore operation from the file object currently being restored using the twin file.

The present disclosure relates to a method, device and computer program product for managing a backup job. Specifically, there is provided a method for managing a backup job, the backup job being used to store a data object to a storage system. In the method, the difference between the data object specified by the backup job and a copy of the data object in the storage system is determined. In response to determining the difference meets a predetermined threshold, a difference area in the data object where there might exist the difference is determined. With respect to a first block within the difference area, in a group of blocks in the data object, the backup job is processed based on a first query result from the storage system, the first query result indicating whether data in the first block differs from data in a corresponding block in the copy.

An efficient method for generating asset backup scheduling plans. Within a data protection environment, at least two service level metrics may be observed—a recovery point object (RPO) and a recovery time objective (RTO). In order to meet acceptable values for these metrics, on par with established service level agreements, infrastructure employed throughout the data protection environment, as well as the scheduling of asset backup operations, tend to grow in complexity. To address service distributions potentially emerging from the aforementioned complexities, the disclosed method proposes a heuristic approach to generating asset backup scheduling plans, which consider factors such as backup device limitations, RPO violation minimization, asset usage, and asset prioritization.
