Abstract: A data processing method includes a DPU that performs an operation in an image operation set on obtained image data to obtain model training data, where the image processing operation set includes at least an image decoding operation, such that the DPU outputs the model training data to a model training processor. The model training data is then used by the model training processor to perform an operation in a training operation set. Alternatively, the DPU outputs model training data to a CPU. The model training data is used by the CPU and the model training processor to perform the operation in the training operation set, and the training operation set includes at least a model training operation.

Abstract: A first compute node sends a first data access request to a first data processing unit (DPU). The first data access request is used to access first data in a storage device. After receiving the first data access request, the first DPU first determines whether the first data is cached in a cache of the first DPU. If the first data is cached in the cache of the first DPU, the first DPU sends the cached first data to the first compute node. If the first data is not cached in the cache of the first DPU, the first DPU obtains the first data from the storage device, and sends the first data to the first compute node.

Abstract: This application provides a data backup system and an apparatus. The system includes a data processing apparatus and a storage device. The data processing apparatus is configured to receive a write request sent by a first host, where the write request carries first data that needs to be backed up to the storage device. The data processing apparatus is configured to perform deduplication and compression operations on the first data, to obtain second data. The data processing apparatus is further configured to write the second data into the storage device.

Abstract: A file access method includes that a second device may initiate a file access request to a first device, where the file access request includes a file identifier of a file. After receiving the file access request, a network interface card of the first device may directly parse the file access request to obtain the file identifier carried in the file access request, then access the file in a memory of the first device based on the file identifier, and send a file access response to the second device. When the first device receives the file access request, the network interface card of the first device may process the file access request without intervention of a processor of the first device.

Abstract: In a method for processing a server message block (SMB) service fault, a first storage device generates a file handle according to a first file open instruction from a host, and sends the file handle to a second storage device. The second storage device stores the file handle as a backup handle. The second storage device activates an Internet Protocol (IP) address of the first storage device according to fault information from the first storage device, and establishes a communication connection to the host. After the second storage device determines a file handle matches the handle identifier, the second storage device opens a file. Hence, when a storage device that processes an SMB service is faulty, the SMB service may be taken over by a secondary storage device such that the SMB service is executed without interruption.

Abstract: A method for implementing messaging services includes receiving a message body sent by a calling user, determining whether the calling user and a called user are in the same IP Multimedia Subsystem (IMS) domain according to user registration information, and sending the message body to the called user if the calling user and the called user are in the same IMS domain. An IMS messaging service system includes a Message Application Server (MAS), a Call Session Control Function (CSCF) entity, a calling User Equipment (UE) and a called UE. A MAS includes a user registration information storing unit, a receiving unit, and a determining unit adapted to determine whether the calling user and the called user are in the same IMS domain according to the user registration information stored in the user registration information storing unit when the receiving unit receives the message body from the calling user, and a sending unit.
