Claim One:
1. A system for supporting fast hybrid reconfiguration in a high performance computing environment, comprising: one or more microprocessors; a first subnet, the first subnet comprising a plurality of switches, the plurality of switches comprising at least a leaf switch, wherein each of the plurality of switches comprise a plurality of switch ports, a plurality of host channel adapters, each host channel adapter comprising at least one host channel adapter port, a plurality of end nodes, wherein each of the plurality of end nodes are associated with at least one host channel adapter of the plurality of host channel adapters; wherein the plurality of switches of the first subnet are arranged in a network architecture having a plurality of levels, each of the plurality of levels comprising at least one switch of the plurality of switches; wherein the plurality of switches is initially configured according to a first configuration method, the first configuration method being associated with a first ordering of the plurality of end nodes; wherein a subset of the plurality of switches is configured as a sub-subnet of the first subnet, the sub-subnet of the first subnet comprising a number of levels fewer than the plurality of levels of the first subnet; wherein the sub-subnet of the first subnet is reconfigured according to a second configuration method; wherein a subset of the plurality of end nodes are associated with the sub-subnet, and wherein traffic between the subset of the plurality of end nodes is confined to the sub-subnet of the first subnet.
