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.

AI training network and method

In a data processing method, a timeout aggregation node of a cluster obtains first data that is partial aggregated data in a data-intensive computing task. The first data carries a first identifier of a timeout node indicating that a timeout occurs on the timeout node. The timeout aggregation node obtains second data of the timeout node based on the first identifier, where the second data is to-be-aggregated data sent by the timeout node. The timeout aggregation node aggregates the first data and the second data according to a preset rule to obtain third data that is complete aggregated data. The timeout aggregation node then notifies each computing node in the cluster of the third data.

Data processing method, apparatus, and device

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.

Data transmission method and related device

A power management method to improve a power-on effect of a multi-node system is disclosed. 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.

Power management method and system

Embodiments of the present disclosure disclose an uplink data transmission method and apparatus and a storage medium. The method comprises: a terminal sending uplink data using an unlicensed resource; if the sending of the uplink data using the unlicensed resource fails, sending the uplink data using a licensed resource; the terminal sending a preamble sequence using an unlicensed resource; sending uplink data in a transmission time interval corresponding to a sending moment of the preamble sequence; and if a random access response carrying uplink authorization information is received within a preset period of time, resending the uplink data using a licensed resource indicated by the uplink authorization information. A base station detects the preamble sequence sent by the terminal using the unlicensed spectrum and the uplink data sent by the terminal, and when the preamble sequence is correctly decoded but the uplink data is not correctly decoded, the random access response carrying the uplink authorization information is sent to the terminal within the preset period of time using the licensed resource.

Uplink data transmission method and apparatus and storage medium

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.
