Embodiment Construction

[0017] A kind of multi-CPU processing system design method that adopts PCIE channel to realize high-speed data exchange of the present invention is described in detail below in conjunction with accompanying drawing.

[0018] Such as figure 1 Shown, a kind of adopting PCIE channel of the present invention realizes the multi-CPU processing system design method of data high-speed exchange, and its characteristics are:

[0019] Lead out the CPU PCIE2.0 X16 interface of each server node, that is, the signals of 16 transmission channels, and use it as a data exchange channel, which can meet the bandwidth of 16GB / S. The signal interface adopts a standard PCIE2.0 interface slot;

[0020] The CPU PCIE2.0 X16 interface of each server node is used as a data exchange channel. Due to the large difference in the spatial position of each node in the server system, the PCIE redriver is used to re-enhance the balance and emphasis of the signal to achieve long-distance transmission;

Abstract

The invention provides a multi-CPU (Central Processing Unit) processing system design method for realizing high-speed data exchange adopting a PCIE (Peripheral Component Interface Express) channel. The multi-CPU processing system design method is characterized in that signals of sixteen transmission channels are led out at the CPU PCIE2.0X16 interface of each server node; the CPU PCIE2.0X16 interface of each server node serves as a data exchange channel; in a multi-node server system, node data of a PCIE data relay allocation pivot are established to be transmitted to the allocation pivot; in the multi-node server system, the PCIE data relay allocation pivot has an automatic expansion capacity, and data allocation quick expansion is realized. Compared with the prior art, multi-CPU processing high-efficiency and low-cost design of the server system can be effectively ensured, the multi-CPU processing reliability and stability of the server system are realized, and the method has important meanings for the usability and stability of the server system.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a design method of a multi-CPU processing system that uses PCIE channels to realize high-speed data exchange. Background technique [0002] Today's cloud computing services have higher and higher requirements for the design of server computing speed. There are many types of CPUs, and motherboards from different manufacturers are widely used in server systems. Cloud computing gradually reduces the differences in hardware. Hardware interconnection design, the current design of the server system can only be carried out through network interconnection as much as possible, which brings about such a problem, that is, the restrictive factors such as low transmission efficiency and poor network security of computing data through the network are extremely serious. Restricts the unified use of hardware under cloud computing. Today, cloud computing undertakes workloads such ...
