Abstract: The present disclosure discloses a data read and write method.

Abstract: Provided are a Hot Backup system and method, and an electronic device and a storage medium. The system includes: an accelerator card, correspondingly connected to a primary server on a one-to-one basis, connected to a standby server in a sharing manner, and configured to acquire operating state information, operation log information, memory information, and configuration information of the primary server, in a case where determining, according to the operating state information, that the primary server has crashed, acquire data to be processed that is to be transmitted to the primary server, and transmit the operation log information, the memory information, the configuration information, and the data to be processed to the standby server; and the standby server, configured to generate, through simulation, a virtual application environment of the primary server and execute an application service of the primary server.

Abstract: The present disclosure discloses a data read and write method.

Abstract: Embodiments of the present application provide a master-slave switching interface structure of a server. The master-slave switching interface structure includes: at least two input/output interfaces and a routing and switching processor. The routing and switching processor includes: a clock buffer module connected to a first clock input source pin; a local clock module connected to a second clock input source pin; a switch module connected to the first clock input source pin, the first clock output pin, and a clock connection pin. The at least two input/output interfaces are connected to the switch module, and one of the at least two input/output interfaces is a target master-slave switching detection interface; and the routing and switching processor is configured for detecting connection status of the target master-slave switching detection interface, and switching a clock transfer direction of the target master-slave switching detection interface based on the connection status.

Abstract: A mainboard includes a plurality of interfaces, a first interface of the plurality of interfaces is configured to be connected to the processor board card having a processor circuit, a second interface of the plurality of interfaces is configured to be connected to a non-processor board card, and the first interface and the second interface are connected to each other via a communication circuit; for the mainboard, a connection-centric design idea is adopted, the processor board card is regarded to have the same status as the non-processor board card; because no processor circuit is provided, and only the first interface connected to the processor board card needs to be provided, compared with an original mainboard, an area of the board card in the present application is reduced, and the processor board card and other non-processor board cards may be connected to the mainboard in a stacked manner.

Abstract: The present application discloses a mainboard, a processor board card, and a computing system.

Abstract: An auxiliary cleaning device for a disabled person, comprising a movable support (1), a leg lifting device (2), and a cleaning device (3). The distances between a cleaning mechanism (33) and a part to be cleaned of a user in a first direction, a second direction, and a third direction are automatically adjusted, such that the cleaning mechanism (33) is driven by a mechanical arm mechanism (32) to move to a designated position near said part, so as to perform an operation such as cleaning of said part.
