[0019] Figure 2 The figure is a schematic diagram of interconnection of a dual-way server motherboard based on a domestic processor according to an embodiment of the present invention. DETAILED DESCRIPTION

When multiple processors process the same data, it is necessary to synchronize the cache data between different central processing units (CPUs). Cluster non-uniform memory access (CC-NUMA), as a distributed memory architecture, will not only occupy the bandwidth of the connection channel between CPUs, but also increase the latency of memory access and consume part of the CPU resources. Based on this dual-processor interconnection channel, a Full Mesh is achieved through a 3-way direct connection interface. Each CPU is reachable within one hop. The data transmission between the two CPUs does not need to be forwarded and processed by other CPUs, and will not occupy additional system resources.
