Abstract: An artificial intelligence training technology, applied to an artificial intelligence training network. Before graphics processing units located on different servers need to communicate with each other, an optical channel used for communication is established in advance. Once a graphics processing unit of a previous server completes calculation of the graphics processing unit, a calculation result can be immediately sent to a graphics processing unit on a next server without waiting or only in a short time period, to reduce duration of artificial intelligence training.

Abstract: The present disclosure discloses a power management method to improve a power-on effect of a multinode system. In the power management method provided in the present disclosure, after a power management module delivers a power-on instruction to each node in the multi-node system, a PCH of each node loads a BIOS from a local flash to perform a power-on process. Compared with the prior art in which a PCH of a master node is responsible for loading BIOSs of all nodes in a multi-node system, the method provided in the present disclosure can reduce burden on the PCH of the master node, and accelerate a power-on speed of the system, so that a better power-on effect is achieved. The present disclosure further provides a related multi-node system.

Abstract: A method for controlling movement of a moving body includes: obtaining a first voxel set of an obstacle, where the first voxel set includes at least one first voxel that identifies the obstacle in space in which the moving body is located; determining a valid moving path based on a mapping relationship between a voxel and a moving path and the first voxel set; and controlling the moving body to move along the valid moving path.

Abstract: A data transmission method, performed by a receive end, includes: receiving notification information that is about to-be-transmitted data and that is sent by a transmit end, where the notification information includes a size of the to-be-transmitted data of the transmit end; generating a plurality of RDMA read requests based on the size of the to-be-transmitted data; and sending the plurality of RDMA read requests to the transmit end, where a bandwidth occupied by data read by the plurality of sent RDMA read requests is less than or equal to an ingress bandwidth of the receive end.
