Abstract: Systems and methods are provided for supporting efficient reconfiguration of an interconnection network having a pre-existing routing. An exemplary method can provide a plurality of switches, a plurality of end nodes, and one or more subnet managers, including a master subnet manager. The method can calculate, via the master subnet manager, a first set of one or more leaf-switch to leaf-switch multipaths. The method can store this first set of one or more leaf-switch to leaf-switch multipaths at a metabase. The method can detect a reconfiguration triggering event, and call a new routing for the interconnection network. Finally, the method can reconfigure the network according to the new routing for the interconnection network.

Abstract: Systems and to provide combined IB and IP address and name resolution schemes via default IB multicast groups in a high performance computing environment, in accordance with an embodiment. A protocol would include options for providing application specific values using TLV (type-length-value) style generic representation. In this way it would be possible to issue requests that have an application specific argument (e.g. IP address) for which an IB address mapping is requested, and it would also be possible to have responses and announcement messages containing an arbitrary set of such TLVs.

Abstract: Systems and methods for providing default multicast local identifier values per subnet partition as additional subnet management agent attributes in a high performance computing environment. In accordance with an embodiment, a single multicast local identifier can be associated with multiple multicast group identifiers when the multiple multicast group identifiers are associated with a same subnet partition. That is, a default MLID for each subnet partition (i.e. either all subnet partitions or those subnet partitions that are defined to have multicast communication) can be provided. A subnet node can have a default multicast local identifier table for storing default multicast local identifiers. A relationship between the partition key table of the node and the default multicast local identifier table of the nod can map default assigned multicast local identifiers to relevant partitions.

Abstract: 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.

Abstract: System and method for supporting virtual machine migration in a high performance computing environment. In accordance with an embodiment, when a virtual machine migrates from a first subnet to a second subnet, a gateway port at the first subnet can, upon receiving packets addressed to the migrated virtual machine, consult a memory lookup table to discover the virtual machine's new addresses. The gateway port can update the packet accordingly. The memory lookup table can be addressed based on a GUID of the virtual machine.

Abstract: A system and method can rout traffic between distinct subnets in a network environment. A router that connects the distinct subnets, such as InfiniBand (IB) subnets, can receive a list of destinations that the router is responsible for routing one or more packets to. Furthermore, the router can obtain information, from one or more switches in the at least one subnet, on which downward output ports of the router can be used for routing the one or more packets, and build a routing table based on the obtained information.
