COMPUTER SYSTEM

摘要

A computer system includes m groups, wherein each group includes n nodes, with m being a natural number greater than or equal to 1, and n being a natural number greater than or equal to 2, each node includes a first node controller and a second node controller, the nodes are connected to each other for information communication directly or indirectly via the first node controller and the second node controller; for those nodes connected to each other directly, the first controller of an arbitrary node is correspondingly connected to the first controller of another node, and the second controller of the arbitrary node is correspondingly connected to the second controller of the other node, so as to form a double interconnection architecture among nodes. The connected nodes in the computer system are directly interconnected via node controllers, interactive information connection across nodes can be achieved without needing any additional interconnection module; in this way, the use of interconnection chips can be reduced, and also the path of cross-node access can be shortened and the access delay time can be reduced; the cost can be reduced, and also the system performance can be improved. ­
