Abstract: This application discloses a task processing method. The method is applied to a computer system, and the computer system includes a user mode and a kernel mode. The user mode includes a plurality of tasks, and the tasks are threads or processes. The method includes: detecting, in the kernel mode, a type of a first request of entering a kernel entry; when the type of the first request indicates that a first task is suspended in the user mode, switching at least from a user-mode context of the first task to a user-mode context of a second task, recording a suspended state of the first task and a running time from a moment of starting to run the first task to a moment of suspending the first task, and skipping processing other scheduling statuses of the first task; and running the second task in the user mode.

Abstract: Examples of phase-change arrays, phase-change memories, and electronic devices are described. In one example, a phase-change storage array includes a number of phase-change storage units, each of which includes a phase-change thin film. The phase-change thin film includes a phase-change material layer and a heterojunction layer, and the phase-change material layer is in contact with the heterojunction layer. The phase-change material layer is formed by using a phase-change material, and the heterojunction layer is formed by using a heterojunction material. A lattice mismatch degree between the heterojunction material and the phase-change material is less than or equal to 20%, a contact crystal surface of the heterojunction material and a contact crystal surface of the phase-change material have a same lattice angle, and a melting point of the heterojunction material is greater than a melting point of the phase-change material.

Abstract: This application relates to the communications field, and in particular, to a head mounted display device for extending a display area of an electronic device and a processing method of the head mounted display device. A display of the electronic device displays first content of an image. The image further includes second content that is not displayed on the display of the electronic device. The head mounted display device obtains, by using an image sensor, the first content displayed on the display of the electronic device, performs projection transformation on the second content, and displays the obtained first content and the second content obtained after the projection transformation on the display of the head mounted display device. Therefore, when image resolution of a to-be-displayed image is greater than display resolution of the display of the electronic device, the entire image is clear without needing to be scaled down or cropped.

Abstract: An example chip may include a substrate, an insulation layer located on a side of the substrate, and a first waveguide and a second waveguide that are in the insulation layer. The second waveguide is located on a side of the first waveguide away from the substrate. A transmission loss of the second waveguide is smaller than a transmission loss of the first waveguide. A first coupling portion of the first waveguide and a second coupling portion of the second waveguide form a first coupling structure, and the first coupling structure is configured to implement optical coupling between the first waveguide and the second waveguide.

Abstract: A method and an apparatus provide network problem location based on subscriber perception. A server firstly receives and parses a call history record CHR log sent by a network management system, then determines, according to a parsing result, whether a call of a subscriber is a key quality indicator KQI exception event, and locates a location and a cause of the KQI exception event. The technical solutions provided in the present invention are capable of finding a network problem and locating the network problem from the perspective of subscriber perception.
