Abstract: A display panel includes a display layer, a photosensitive layer and an infrared mask. The display layer is configured to display an image, the display layer has light-transmitting portions, and the light-transmitting portions are configured to transmit infrared light. The photosensitive layer is disposed on a side of the display layer. The infrared mask is disposed on a side of the photosensitive layer proximate to the display layer, the infrared mask has hollowed-out regions, the hollowed-out regions are configured to make the infrared mask have a preset pattern, and a region in the infrared mask except the hollowed-out regions is configured to prevent transmission of the infrared light. The photosensitive layer is configured to receive infrared light passing though the hollowed-out regions and the light-transmitting portions, and convert the infrared light into an image signal.

Abstract: This application provides a cloud system resource set recommendation method. After receiving a cloud system resource set recommendation request (401) triggered by a user and used to request to obtain cloud system resource sets that can support a target cloud service and meet a performance requirement, the recommendation apparatus selects, based on the cloud system resource set recommendation request (401), from the existing cloud system resource sets supporting the target cloud service, a target cloud system resource set meeting the performance requirement (402), and feeds back the target cloud system resource set to the user (403). The user does not need to select a required cloud system resource set from several limited resource sets with fixed configurations, but only needs to notify the recommendation apparatus of a target cloud service and a performance requirement that need to be supported by the cloud system resource set.

Abstract: A lock management solution in a cluster, where the cluster includes a client and a lock server, the lock server includes an interface card and a memory, the memory stores a read lock request queue recording an identifier of a client waiting for a read lock or obtaining the read lock, the memory further stores a write lock request queue recording an identifier of a client waiting for a write lock or obtains the write lock, and the memory further includes a read lock allocation count and a write lock allocation identifier, where the read lock allocation count records an allocated read lock, and the write lock allocation identifier indicates whether the write lock has been allocated.

Abstract: A method and system for taking over devices are provided. In a solution, a first control board first performs topology discovery on a Peripheral Component Interconnect Express (PCIE) bus, and reserves resources for a Switch (SW) where a NON-Transparent (NT) bridge is located and devices connected to down ports of the SW according to a set resource reservation policy when the topology discovery proceeds to the NT bridge, where the SW and the devices are currently controlled by a second control board. After the SW and the devices are taken over from the second control board, the resource reserved in advance may be allocated to the SW and the devices, so that the devices that are taken over operate normally under control of the first control board. Dual control is implemented through direct taking over devices, and a response speed for processing a device request is improved.
