Abstract: This application provides a model training system and method. The system includes a first group, where the first group includes an MEMS and S×C processors, S is a quantity of nodes in the first group, C is a quantity of processors in one node, and both S and C are positive integers, the MEMS, configured to construct an optical transmission channel between any two of the S nodes, and the S×C processors, configured to jointly train a model. In one iteration of joint model training, the S×C processors are configured to run model training in respective processors, to obtain respective corresponding data. At least two of the S×C processors transmit target data through the optical transmission channel. A processor that receives the target data may be configured to adjust a parameter for model training in the processor based on the target data.

Abstract: A remote data access method is applied to a first device that is coupled to and communicates with a second device. The first device and the second device each are configured with a network interface card (NIC) having a remote direct memory access (RDMA) function. The method is performed by a NIC of the first device, and the method includes: generating a first packet including a type identifier and a function identifier; and sending the first packet to the second device. The type identifier in the first packet indicates that the first packet is a remote memory function call (RMFC)-type packet, and the RMFC-type packet indicates the second device to perform a preset operation on local data of the second device. The function identifier in the first packet indicates an operation type of the preset operation.
