Abstract: Systems and methods for on-demand unicast forwarding in a high performance computing environment, in accordance with an embodiment. An exemplary method can provide, at a computer comprising one or more microprocessors, a plurality of switches, a plurality of host channel adapters, and a plurality of hosts. The method can provide, at two rails, redundant connectivity between the plurality of hosts, wherein each rail comprises a set of the plurality of switches. The method can detect a disruption i connectivity between two hosts of the plurality of hosts. The method can re-establish communication between the two hosts of the plurality of hosts via unicast packets on an inter-rail link, the inter-rail link being provided between the two rails.

Abstract: A system and method can provide fault tolerance in a middleware machine environment. A subnet manager can determine whether there is a path record change when a fault occurs in the middleware machine environment. Furthermore, the subnet manager can signal a dynamic reconfiguration event to at least one host in the middleware machine environment. The at least one host can send a message to the subnet manager to query for a latest path record. Then, the subnet manager can provide a latest path record to the at least one host.

Abstract: Systems and methods for using InfiniBand routing algorithms for Ethernet fabrics in a high performance computing environment. 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.
