Embodiments of this application disclose a computing system, an addressing method, a compute node, and a program product, and pertain to the computing field. Each compute node in a computing system has a different first-level identifier, and a plurality of function modules in each compute node have different second-level identifiers. The second-level identifier is used for routing and addressing between function modules in a same compute node, and the first-level identifier and the second-level identifier are used for routing and addressing between function modules in different compute nodes. In other words, unified addressing is performed on the different compute nodes, and is also performed on the function modules in the same compute node. In this way, interconnection specifications used during communication between the compute nodes and communication in the compute node are consistent, complex protocol conversion is not needed, data processing efficiency is improved, and latency is reduced.
