Disclosed are an isolation method for a high-performance computer system, and a high-performance computer system. The isolation method comprises node-level isolation performed. The node-level isolation comprises: configuring a routing table for each computing node, and configuring, in the routing table, valid routing information for computing node pairs; when any one source computing node needs to communicate with a target computing node, determining, by lookup, whether valid routing information exists between the source computing node and the target computing node according to the configured routing table; if so, allowing the source computing node to communicate with the target computing node; otherwise, forbidding the source computing node from communicating with the target computing node. The disclosure can realize network security isolation of the high-performance computer system, and guarantee the security and reliability of high-performance computers under the premise of ensuring flexible expansion and high availability of high-performance computing resources.

This invention discloses a hierarchical switching fabric and deadlock avoidance method for ultra high radix network routers. The hierarchical switching fabric comprises a network-on-chip and K multi-port components. The multi-port component comprises a port module configured to receive packets by a high speed serializer/deserializer, code and format the packets, send the packets to a corresponding hyper packet module after coding and format conversion, and send the packets sent by the hyper packet module to the network; and the hyper packet module configured to perform protocol processing for the received data link level packets, discard illegal packets, forward legitimate packets to the network-on-chip, perform data error correcting, format conversion and channel mapping for the packets received from the network-on-chip, and send the packets to the corresponding port module.
