An information transmission method and a related device applied to a cloud service system are provided. The cloud service system includes an arbiter, a first switch, and a first server group. The arbiter is connected to the first server group by using the first switch. The method includes: a first server obtains a first identifier of the first server in the first server group. The first server determines, in a first slot, a first time domain location corresponding to the first identifier. The first time domain location is a time domain location at which the first switch receives a first request to be processed by the arbiter, and different identifiers correspond to different time domain locations in the first slot. The first server sends the first request to the first switch based on the first time domain location.

Embodiments for communicating using a switch configured to establish multiple types of communication routes. First and second upstream switch ports (USPs) communicate with first and second hosts according to first and second Compute Express Link (CXL) protocols, respectively. A downstream switch port (DSP) communicates with a device according to a third CXL protocol. The switch couples the first USP to the DSP via a first route traversing a single Virtual CXL Switch (VCS), and couples the first USP to the second USP via a second route traversing two VCSs. Optionally, the switch includes a Resource Provisioning Unit (RPU) coupling the two VCSs of the second route, terminating the first and second CXL protocols, and translating between CXL messages conforming to the first and second CXL protocols.

A system comprises a reconfigurable processor including a network of a plurality of switches; an array of configurable units connected to the network and configured to execute an application. Each switch includes a plurality of input and output ports. A first input port of a switch is coupled to a first memory having a first bandwidth and a second input port of the switch is coupled to a memory having a second bandwidth. The switch is coupled to transfer a first data from the first memory via the first input port and a second data from the second memory via the second input to a common output port. The system includes an arbiter that selects the first input port and the second input port to transfer data to the common output port for a time proportional to the first bandwidth and the second bandwidth respectively.

This application provides a data processing method, applying to a distributed computing system including a plurality of computing nodes and at least one first switch node. After receiving control information from a computing node, the first switch node creates a multicast job based on the received control information. The multicast job includes multicast destination information. Then, the first switch node obtains multicast data based on the multicast job, and sends the multicast data to the computing node based on the multicast job. In the distributed computing system, when the plurality of computing nodes execute a service that requires multicast, there is no need to configure related multicast information in advance. Instead, when the multicast is required, a computing node that participates in the multicast sends control information to a switch node, and the switch node creates a multicast job based on the control information to implement the multicast.
