1. A multiprocessor computer system including a processor interconnect network, comprising:
a plurality of groups of routers, wherein the plurality of groups of routers are interconnected through an intergroup interconnection network, each group of routers comprises a respective plurality of local routers locally coupled to each other router in the corresponding plurality of local routers through a respective intragroup interconnection network, wherein at least a particular router in a particular one of the plurality of groups of routers is to:
access at least one routing table from a plurality of routing tables, wherein the plurality of routing tables comprises at least one local routing table corresponding to the intragroup interconnection network of the particular group of routers and a plurality of global routing tables corresponding to the intergroup interconnection network;route data to another router coupled to the intergroup interconnection network by selecting a network path from among a plurality of network paths from a target node to a destination node in the network based on the at least one routing table, wherein the plurality of global routing tables include:
a non-minimal table to route non-minimal traffic to an intermediate group of routers that is connected to all other groups of routers in the plurality of groups of routers,a minimal table to determine a direct path from one router group to another router group in the plurality of router groups,network congestion information corresponding to the intragroup interconnection network of the particular group of routers, andfailed network link information corresponding to the intragroup interconnection network of the particular group of routers, wherein the network path is selected based on one or more of the network congestion information and failed network link information. |
