Abstract
A multiprocessor computer system includes a plurality of processor nodes and at least a three-tier hierarchical network interconnecting the processor nodes. The hierarchical network includes a plurality of routers interconnected such that each router is connected to a subset of the plurality of processor nodes; the plurality of routers are arranged in a hierarchy of n≧3 tiers (T, . . . , T); the plurality of routers are partitioned into disjoint groups at the first tier T, the groups at tier Tbeing partitioned into disjoint groups (of complete Tgroups) at the next tier Tand a top tier Tincluding a single group containing all of the plurality of routers; and for all tiers 1≦i≦n, each tier-Tsubgroup within a tier Tgroup is connected by at least one link to all other tier-Tsubgroups within the same tier Tgroup.
