The invention relates to the technical field of
chip computing network
interconnection, in particular to a Mesh and
Dragonfly fused
chip computing network networking method, which comprises the following steps: firstly, adopting Mesh topology to interconnect computing nodes in a local range to form a POD unit, and enabling POD internal nodes to be only directly connected with adjacent nodes; abstracting a POD edge routing node into an
external connection channel as a unique interface of cross-unit communication; then, taking the POD as a basic unit, constructing a switch-free multi-stage
Dragonfly topology through an
external connection channel, and directly undertaking a cross-group connection function by an edge routing node; a symmetric
interconnection rule and a port retention rule are followed in the networking process. Core advantages of the Mesh topology and the
Dragonfly topology are fused, low-overhead and efficient communication in the POD is achieved by means of the Mesh topology, global communication
delay is reduced through the switchless Dragonfly topology, meanwhile, the excellent multi-level expansion capacity is achieved, the hardware area and
power consumption overhead can be reduced, the method is compatible with various computing node types, and multi-field networking requirements are met.
