A chiplet system and a positioning method thereof are provided. The positioning method of the chiplet system includes the following steps. Two end chiplets and a plurality of middle chiplets are classified. A quantity calculation packet is transmitted and accumulated from each of the end chiplets towards another end to analyze a quantity of middle chiplets. A serial number comparison packet is transmitted and accumulated from each of the middle chiplets connected to one of the end chiplets towards another end to set a starting point. An identify number setting packet is transmitted and accumulated from the middle chiplet set as the starting point towards another end to set a positioning number of each of the middle chiplets.

A computer includes first and second computer devices of a first class. Each computer device of the first class includes first and second external ports, at least one memory controller to attach to external memory, and routing logic to route data from the first external port to one of the memory controller and the second external port. The computer further includes first and second computer devices of a second class. The first computer device of the second class is connected to the first external ports via respective first and second links. The second computer device of the second class is connected to the second external ports via respective third and fourth links. The first and second computer devices of the second class include processing circuitry to execute a computer program and are connected to the first and second links, or third and fourth links, respectively to transmit and receive messages.
