SYSTEM AND METHOD FOR EFFICIENT NETWORK RECONFIGURATION IN FAT-TREES

摘要

Systems and methods are provided for supporting efficient reconfiguration of an interconnection network having a pre-existing routing comprising. An exemplary method can provide, a plurality of switches, the plurality switches comprising at least one leaf switch, wherein each of the one or more switches comprise a plurality of ports, and a plurality of end nodes, wherein the plurality of end nodes are interconnected via the one or more switches. The method can detect, by a subnet manager, a reconfiguration triggering event. The method can compute, by the subnet manager, a new routing for the interconnection network, wherein the computing by the subnet manager of the new routing for the interconnection network takes into consideration the pre-existing routing and selects the new routing for the interconnection network that is closest to the pre-existing routing. The method can reconfigure the interconnection network according to the new routing.

1. A method for supporting efficient reconfiguration of an interconnection network having a pre-existing routing comprising:
providing, at one or more computers, including one or more microprocessors,
a plurality of switches, the plurality switches comprising one or more leaf switches, wherein each of the one or more leaf switches comprise a plurality of ports, anda plurality of end nodes, wherein the plurality of end nodes are interconnected via the one or more leaf switches; detecting, by a subnet manager, a reconfiguration triggering event; computing, by the subnet manager, a new routing for the interconnection network, wherein the computing by the subnet manager of the new routing for the interconnection network takes into consideration the pre-existing routing and selects the new routing for the interconnection network that is closest to the pre-existing routing; and reconfiguring the interconnection network according to the new routing for the interconnection network.
