Abstract: A one-way airflow dual fan assembly of dismantling ease, comprising a first installation casing and a second installation casing, the first installation casing is aligned with the second installation casing, a flap is respectively fixed in both the first installation casing and the second installation casing, a cover plate is provided in the flap, connection mechanisms are provided between the cover plate and the flap, the flap is connected with the cover plate via the plurality of connection mechanisms, and the connection mechanisms comprise respectively a flexible connection component and a limiting part. By cooperation of the cover plates and the connection mechanisms, by pulling the cover plates, under limiting actions of the second wedges, the first wedges are pressed, the U-shaped connection blocks deform flexibly until the flexible connection components are released, and the cover plates are released from the flaps, so that the cover plates can be disassembled.

Abstract: A computer subsystem and a computer system, where the computer subsystem includes L composite nodes (CNs), each CN includes M basic nodes, each basic node includes N central processing units (CPUs) and one node controller (NC). Any two CPUs in each basic node are interconnected. Each CPU in each basic node is connected to the NC in the basic node. The NC in each basic node has a routing function. Any two NCs in the M basic nodes are interconnected. A connection between the L CNs formed through connections between NCs enables communication between any two NCs to be no more than three hops. Hence, the computer subsystem and the computer system can reduce the kinds and the number of interconnection chips, and simplify an interconnection structure of a system, thereby improving reliability of the system.

Abstract: The present invention provides a node routing method of a multi-processor system, a controller and a multi-processor system. The method includes learning a state of an available link between nodes in the multi-processor system, where the multi-processor system includes a first subnet and the first subnet includes at least two connected nodes, and when at least one link in the first subnet fails, reselecting an available link between all nodes in the first subnet, so that the nodes in the first subnet use the reselected available link to route a packet, where the reselected available link is a link on each node in the first subnet except a link whose dimension sequence number is the same as that of the failed link, a dimension sequence number is numbers of a link at two end nodes, and numbers of a link at two end nodes are the same.

Abstract: The present invention discloses a method for retransmitting a data packet in a quick path interconnect system, and a node. When a first node serves as a sending end, only the first data packet detected to be faulty is retransmitted to a second node, thereby saving system resources that need to be occupied in the data packet retransmission. When the first node serves as a receiving end, it implements that the packet loss does not occur in the first node in a case that the second node only retransmits the second data packet detected to be faulty, thereby ensuring reliability of the data packet transmission based on the QPI bus.
