Abstract: Systems and methods for dynamically assigning membership in a data partition to an end-port of a requesting host channel adapter. An exemplary embodiment can provide a subnet manager configured to operate within a subnet of a network fabric. The subnet can include a plurality of nodes, and the plurality of nodes can include at least one switch and a plurality of end-nodes, where the subnet manager executes on one of the plurality of nodes. A host channel adapter of a node in the subnet can request membership for an end-port of the host channel adapter. In response to the request, the subnet manager can request data from the data store to confirm that the end-port is a member of an admin partition and that the admin partition is associated with the data partition in which membership was requested.

Abstract: Systems and methods for defining virtual machine fabric profiles of virtual machines. An exemplary embodiment can provide a virtual machine identifier, a virtual host channel adapter instance ID, and a virtual globally unique identifier. The virtual machine identifier, virtual host channel adapter instance ID, and virtual globally unique identifier can be mapped to each other so that the virtual host channel adapter instance ID, and virtual globally unique identifier can be retrieved through access to the virtual machine identifier. Further, a relationship can be created between a P_Key that defines an admin partition and the virtual globally unique identifier, where the relationship between the P_Key and the virtual globally unique identifier defines the virtual globally unique identifier as a member of the admin partition defined by the P_Key.

The method can provide, at a computer comprising one or more microprocessors, a plurality of switches, a plurality of hosts, a topology provider (TP) module, a routing engine (RE) module, and a switch initializer (SI) module. The method can perform a discovery sweep, by the TP, of the plurality of hosts and the plurality of switches and assigns an address to each of the plurality of hosts and the plurality of switches. The method can calculate, by the routing engine, a routing map, based upon a routing scheme, for the plurality of hosts and the plurality of switches, the routing map comprising a plurality of forwarding tables. The method can configure, each of the plurality of switches with a forwarding table of the plurality of forwarding tables calculated by the routing engine.

Abstract: Systems and methods of reserving a specific queue pair number for proprietary management traffic in a subnet of a high performance computing environment. An exemplary embodiment can provide a host channel adapter (HCA), including a control circuit with a processor and a memory, and at least one port operative to connect the HCA to a network fabric. Additionally, the HCA can include a subnet management agent (SMA) that executes on the HCA, and a configurable attribute stored in the memory of the HCA. A communication including a number value, can be received by the subnet management agent from a subnet manager of the subnet. The value of the configurable attribute can be set equal to the value of the received number. A QP number that corresponds to the set number value of the configurable attribute can then be reserved for sending and receiving proprietary network management traffic.

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 methods for supporting inter subnet partitions in a high performance computing environment. In accordance with an embodiment, a fabric manager can define a range of P_Key values, among a plurality of P_Key values, as a inter subnet partition (ISP) P_Key range. The fabric manager can communicate this defined range of P_Key values to a number of subnets, via their subnet managers. The subnet managers in each subnet retain management over their subnets. As there is no central management that configures each side of inter subnet communication, subnet managers on within participating subnets can set up ISP membership, and then exchange information with the other subnet.
