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.

Abstract: Systems and methods for supporting resource quotas for multicast group creation and membership in a high performance computing environment. In accordance with an embodiment, multicast group membership can present an issue in that inter-subnet partitions can, if left unchecked, runaway with multicast group creation within any given connected subnet. This can starve address map resources at router ports. A quota can be supplied that provides a maximum number of multicast groups any given inter-subnet partition is allowed to create within any given subnet.

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 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: 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: 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: 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.

Abstract: Systems and methods for supporting SMA level abstractions at router ports for enablement of data traffic in a high performance computing environment. In accordance with an embodiment, a subnet manager in a local subnet is responsible for enabling data traffic between subnets in a high performance computing environment. The SM can configure and set a data attribute at a switch port configured as a router port such that incoming data packets can be checked against the attribute to determine whether the data packet's destination is allowed or disallowed to receive inter-subnet data traffic.

Abstract: Systems and methods for supporting SMA level abstractions at router ports for GRH to LRH mapping tables in a high performance computing environment. Ingress port mapping of GRH to new LRH can be reduced to minimally include DGID to DLID mapping. By further reducing the complexity by assuming all packets received at a subnet are addressed to a correct subnet (and also taking into account that correct subnet destination can be checked independently of the individual mapping entries), the DGID address can be simplified to a DGUID address, allowing for additional mappings within a same memory size.
