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.

Abstract: 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.

Abstract: 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.

Abstract: In a method for operating a data object, a first node obtains a request for operating a target data object. The first node determines the target data object is stored on a second node, and sends an operation request for the target data object to the second node. The operation request contains an identifier that identifies a target operation to be performed on the target data objects, and instructs the second node to perform an operation indicated in the operation request. The type of the target operation is search, insertion, modification, creation, or deletion.

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.
