There may be multiple matching CXL devices. When there are multiple matching devices, the matching target CXL device is determined based on the shortest connection path principle.

[0085] S32, for each matching CXL device to be selected, find the shortest connection path to the target processor, including:

[0086] S321: Build an optional node adjacency graph, copy a real-time node adjacency table, and then, based on the CXL Switch port configuration information table, create a new directed graph with all possible connections of all CXL Switch internal nodes, and update the real-time node adjacency table based on the new directed graph.

[0087] S322: In the directed graph, the CXL device to be matched is set as a vertex, and the edge weight is Wij (representing the edge weight between nodes i and j). In this embodiment, all Wij values ​​are set to 1. The value of Wij can also be set based on factors such as performance and bandwidth.

[0088] S323 , starting from the candidate CXL device, find the shortest connection path in the directed graph, and then record the connection status and path length of the shortest connection path; the algorithm for determining the shortest connection path may be Dijkstra algorithm or other algorithms.

[0089] S33: The matching module compares the path distances of each matched CXL device, selects the CXL device with the shortest path distance as the target CXL device of the host system, and records the shortest connection path between the target CXL device and the target CPU. The matching module then marks the target CXL device as configured in the device information table and, based on the shortest connection path, issues a configuration instruction to the relevant CXL Switch (target CXL switch), configuring the CXL Switch. The CXL Switch configuration information is then updated and saved. The real-time node adjacency table is then updated based on the latest configuration.

[0090] As shown in Figure 12, assume that CXL device 4 is the target CPU of the host system, and the CXL device that matches the target CPU is node 8. Now find a connection path between node 8 and node 4 and calculate the distance between the connection paths. The following steps are included:

[0091] S1201: Build a node connection graph, which shows all possible connections between nodes within the CXL switch. The real-time node adjacency table is modified accordingly. Node 8 is connected only to node 44, which is a CXL switch node.

[0092] S1202: Search the internal ports of the CXL switch for any ports connected to the CXL switch. Currently, only node 43 is connected to the external CXL switch. Node 27 is found to be connected to node 43, and node 27 is a CXL switch node. Then, search the internal ports of the CXL switch for any ports connected to the CXL switch or nodes connected to node 4. It is found that only node 26 is connected to the external CXL switch. Node 33 is found to be connected to node 26, and node 33 is a CXL switch node. Then, search the internal ports of the CXL switch for any ports connected to the CXL switch or nodes connected to node 4. Node 34 is found to be connected to node 4, thus establishing the node connection graph shown in FIG13 .

[0093] In step S1203, all edge weights in the node connection graph are set to 1. The Dijkstra algorithm is then used to calculate the distances between the shortest connection paths. Since there is only one path between node 8 and node 4, the path 8->44->43->27->26->33->34->4 is the shortest connection path. Based on the shortest connection path and the port connectivity between the nodes, configuration commands are issued to CXL Switch 1, CXL Switch 2, and CXL Switch 3 to connect ports 44 and 43, ports 26 and 27, and ports 33 and 34. Device 8 is now connected to CPU node 4, establishing a host system.

[0094] S4, read the configuration information of other CXL devices in the host system, repeat S3 until all CXL devices in the host system are matched, mark the CXL devices matched by the host system as configured in the device information table, and complete the configuration of the CXL Switch at the same time, and the host system is built.

[0095] S5, reading the configuration information of the computing system to obtain the configuration information of the next host system, until all host systems are matched and configured, and the computing system is constructed by multiple host systems.

[0096] In summary, this embodiment addresses the need for automatically building a computing system based on the CXL architecture and proposes a method for automatically building a computing system.
