Abstract: Embodiments of this application describe a computer boot method, a controller, a storage medium, and a system, to improve a boot security level of a computer, and avoid a security risk caused by using a tampered boot program file. In a method, a controller is separately connected to a computer hardware system and a BIOS file storage apparatus. The controller obtains a first boot program file in the BIOS file storage apparatus when the controller is powered on and run. The controller establishes a connection between the BIOS file storage apparatus and the computer hardware system when the first boot program file is successfully checked, so that when the connection between the BIOS file storage apparatus and the computer hardware system is successfully established, the computer hardware system completes power-on and running by using the first boot program file.

Abstract: This application provides a hard disk format conversion method and apparatus, and a storage device, and belongs to the field of storage technologies. In this application, a storage format of a storage unit is converted from an SMR format to a PMR format. Because IOPS in the PMR format is higher than IOPS in the SMR format, IOPS in the storage unit can be increased after the storage format is converted. Alternatively, a storage format of a storage unit is converted from the PMR format to the SMR format. Because a storage capacity in the SMR format is higher than a storage capacity in the PMR format, a storage capacity of the storage unit can be increased after the storage format is converted.

Abstract: Methods, systems and media for random semi-structured row-wise pruning of filters of a convolutional neural network are described. Rows of weights are pruned from kernels of filters of a convolutional layer of a convolutional neural network according to a pseudo-randomly-generated row pruning mask. The convolutional neural network is trained to perform a particular task using the pruned filters that include the rows of weights that have not been pruned from the kernels of filters. The process may be repeated multiple times, with the best-performing row pruning mask being selected for use in pruning row weights from kernel filters when the trained convolutional neural network is deployed to processing system and used for an inference. Computation time may be decreased further with the use of multiple parallel hardware computation units of a processing system performing pipelined row-wise convolution.

Abstract: This disclosure provides a data sending method and apparatus, and a device, and pertains to the field of communications technologies. An example method includes: receiving an uplink data packet sent by UE; if a signaling message is carried in the uplink data packet, separating the signaling message from the uplink data packet, where the signaling message is used to request to establish a PDU session or request to activate an established PDU session; forwarding the signaling message to a control plane device; and before an available PDU session exists, forwarding, based on a data forwarding message carried in the uplink data packet sent by the UE, data in the uplink data packet sent by the UE.

Abstract: A power connector includes a housing and a clamp group disposed in the housing. An insertion opening is formed at one end of the housing, and the insertion opening is configured to plug in a plug. The clamp group includes an inner clamp and an outer clamp. An insertion slot is formed in the inner clamp, and the insertion slot is opposite to the insertion opening and is configured to accommodate a front end portion of the plug. The outer clamp is disposed to extend over the inner clamp. When the plug passes through the insertion opening and is plugged into the insertion slot, a contact end of the outer clamp close to the insertion opening presses against a conductive surface of the plug. A contact segment of the inner clamp also presses against the conductive surface of the plug.

Abstract: This application provides an authentication method and related device and system. The method includes sending, by a first network device, a first next-hop resolution protocol (NHRP) registration request message to the second network device, where the first NHRP registration request message is used to request the second network device to perform digital certificate authentication on the first network device, and the first NHRP registration request message includes first PKI certificate information. The method may further include receiving, by the first network device, a first NHRP registration reply message indicating that the digital certificate authentication performed by the second network device succeeds. In this way, authentication is performed between a spoke device and a hub device using a PKI certificate. This helps reducing authentication workload and improving authentication security.
