Abstract: An application control method and a mobile terminal are provided. The method is applicable to a mobile terminal including a processor and an artificial intelligence (AI) module. Whether a current user is a registered user is detected by the processor when detecting that an application running on the mobile terminal belongs to a preset application set.

A monitoring strategy of the running application associated with the registered user is acquired by the AI module, where the monitoring strategy includes a monitoring parameter and a corresponding monitoring parameter threshold. The running application is closed by the AI module when detecting that a value of the monitoring parameter of the running application is greater than or equal to the monitoring parameter threshold.

Abstract: This disclosure generally relates to time and timer techniques that may be used to virtualize one or more virtual machines. In an example, it may be possible to save and restore a timer of a virtual machine while preserving timer information associated with the timer (e.g., an expiration time, whether the most recent expiration has been signaled, and the enable bit, etc.). For example, a first mode may enable restoring a timer based on a previously-existing enable bit, thereby retaining the state of the timer (e.g., whether the timer is programmed to fire and/or whether the most recent expiration has been signaled). By contrast, a second mode of setting a timer may automatically set the enable bit, thereby automatically enabling the timer to fire, as may be expected by a virtual machine when setting a timer.

Once the firmware update package is applied to the coherent hardware accelerator, the system resumes the operation on the coherent hardware accelerator.

Abstract: Techniques for actor and thread message dispatching are described herein. In some examples, a computing system may include multiple actors and multiple processing threads. Upon receiving an incoming message associated with one of the actors, a dispatching component may select one of the multiple processing threads within the computing system to which to dispatch the message for processing. If the associated actor is already assigned to one of the processing threads, then that processing thread may be selected for processing of the message. By contrast, if the associated actor is not already assigned to one of the processing threads, then a processing thread may be selected based on various factors, such as a set of priorities associated with the processing threads.

Abstract: In an approach to collecting and processing performance metrics, one or more computer processors assign an identifier corresponding to a first workload associated with a first virtual machine. The one or more computer processors record resource consumption data of at least one processor at a performance monitoring interrupt. The one or more computer processors create a relational association of the first workload and the first virtual machine to the resource consumption data of the at least one processor. The one or more computer processors determine if the first workload is complete. Responsive to determining that the first workload is not complete, the one or more computer processors calculate a difference in recorded resource consumption data between the performance monitoring interrupt and a previous performance monitoring interrupt.
