Abstract: Systems and methods for supporting SMA level handling to ensure subnet integrity in a high performance computing environment. In accordance with an embodiment, in order to ensure subnet integrity, a SMA at an entry port can operate such that all incoming packets are forwarded to an embedded processor (firmware) no matter where the packet is addressed. Each incoming packet can thus be filtered by an embedded processor. If the packet is valid (for example, includes a second receiver flag and is addressed appropriately), the packet can be allowed. However, if some portion of the validation fails, the packet can be dropped before being allowed entry into the subnet, thus ensuring the integrity of the subnet from erroneous and/or dangerous packets.

Abstract: System and method for supporting scalable representation of switch port status in a high performance computing environment. In accordance with an embodiment, a scalable representation of switch port status can be provided. By adding a scalable representation of switch port status at each switch (both physical and virtual)—instead of getting all switch port changes individually, the scalable representation of switch port status can combine a number of ports that can scale by just using a few bits of information for each port's status.

Abstract: System and method for supporting node role attributes in a high performance computing environment. In accordance with an embodiment, a node role attribute can comprise a vendor defined subnet management attribute. When a subnet manager attempts to discover a high performance computing environment, such as an InfiniBand subnet, or a switch topology, identifying a topology is quite complex when subnet manager can only observe connectivity, without context behind the connectivity (the roles of the different nodes in the connectivity). However, when a subnet has a node role attribute enabled, the subnet manager can map the interconnect more effectively as it can discover not only the connectivity during the initial sweep, but it can also discover the role of each node discovered, thus leading to a more efficient interconnect discovery.

Abstract: System and method for supporting a flexible framework for extendable SMA attributes in a high performance computing environment. In accordance with an embodiment, an information attribute can provide for enhancements in a number of areas. For example, in addition to indicating which version of an interface a queried node supports, the information attribute can additionally provide a mask indicating which vendor specific SMA attributes the node supports. In this way, a subnet manager can identify a version of an interface at each node in a subnet, as well as each node's SMA attribute capabilities. In turn, this allows nodes to run different versions of an interface within a same subnet, without introducing confusion.

Abstract: Systems and methods for supporting SMA level abstractions at router ports for inter-subnet exchange of management information in a high performance computing environment. In accordance with an embodiment, a subnet manager in a local subnet is responsible for establishing and configuring a remote attribute a switch having a switch port configured as a router port. This remote attribute can comprise certain information about the local subnet, including connectivity information and port status information. On receiving a query from a remote subnet manager, via a SMP (or a vendor specific SMP), information contained in the remote attribute can be communicated back to the remote subnet manager.

Abstract: System and method for supporting scalable representation of link stability and availability in a high performance computing environment. A method can provide at attribute at each node in a subnet, wherein the attribute provides a single location at each node for a subnet manager to query the stability and availability of each link connected to the queried node. The attribute can be populated and maintained by a subnet management agent residing at the node.

Abstract: Systems and methods for supporting unique multicast forwarding across multiple connected subnets in a high performance computing environment. In accordance with an embodiment, by enforcing that incoming (i.e., incoming on a router port of a subnet) multicast packets have SGIDs (source global identifiers) that correspond to a restricted set of source subnet numbers when entering the ingress router ports to a local subnet, it is possible to ensure that multicast packets sent from one subnet are never returned to the same subnet through a different set of connected router ports (i.e., avoid looping multicast packets).

Abstract: A system and method can support a scalable packet forwarding mechanism in a middleware machine environment. The middleware machine environment can comprise one or more network switch instances, wherein each network switch instance is associated with one or more external ports that are adapted to receive data packets from an external network. Furthermore, the middleware machine environment can comprise a plurality of packet dispatching components, each of which is responsible for forwarding a data packet to a virtual machine on a host server that operates to process the data packet. Additionally, a link aggregation component can combine multiple external ports into a logical port, and wherein the bandwidth of the logical port is linearly scaled accordingly to a total number of the multiple external ports.

Abstract: Systems and methods for supporting consistent path records across multiple subnets in a high performance computing environment. In accordance with an embodiment, a local inter-subnet manager (ISM) can determine one or more limitations associated with a calculated local path record. The local ISM can, upon receiving information regarding path limitations from a connected subnet, determine which limitations should be applied to inter-subnet traffic.

Abstract: Systems and methods for supporting inter subnet control plane protocol for consistent multicast membership and connectivity across multiple subnets in a high performance computing environment. In accordance with an embodiment, by associating a multicast group with an inter-subnet partition, and enforcing a dedicated router port for the multicast group, multicast loop avoidance can be provided for between connected subnets. Because only a single router port is selected as being capable of handling the MC packet, no other router port in the subnet can then pass a multicast packet back to the originating subnet.
