Abstract: Systems and methods for path record handling in a fabric without host stack cooperation in a high performance computing environment. In a case where the subnet manager has determined “homogenous subnet/fabric” or “semi-homogenous subnet/fabric” status for the current topology, but is still receiving path queries, the subnet manager can use the relevant status to avoid any route evaluation and generate path record either only based on the configuration status of the requesting port in the homogenous case, or by comparing the configuration status of both ports in the semi-homogenous case.

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: Systems and methods can provide for fabric level verification of host defined port GUIDs in a high performance computing network. A lightweight scheme for fabric level verification of host defined port GUIDs is provided wherein a virtual machine is assigned a set of GUIDs that travel with the virtual machine, even on migration or re-start.

Abstract: Systems and methods for InfiniBand fabric optimizations to minimize SA access and startup failover times. A system can comprise one or more microprocessors, a first subnet, the first subnet comprising a plurality of switches, a plurality of host channel adapters, a plurality of hosts, and a subnet manager, the subnet manager running on one of the one or more switches and the plurality of host channel adapters. The subnet manager can be configured to determine that the plurality of hosts and the plurality of switches support a same set of capabilities. On such determination, the subnet manager can configure an SMA flag, the flag indicating that a condition can be set for each of the host channel adapter ports.

Abstract: Systems and methods for supporting coordinated link up handling following a switch reset in a high performance computing environment. Systems and methods can ensure that when a switch of a fabric is rebooted, HCA ports connected to that switch will be set in Active state at the same time even though link training times for different ports may vary with up to several seconds.

Abstract: System and method for providing an InfiniBand network device having a vendor-specific attribute that contains a signature of the vendor. An exemplary embodiment can provide an InfiniBand compatible network device from a vendor. The vendor can further define a subnet management attribute, where the subnet management attribute has an attribute identifier in the range of attribute identifiers reserved in the InfiniBand specification. The vendor can define a signature bit string that is a fixed number of bits in length and a number of offset bits, where the number of offset bits indicates the start of the signature bit string within the attribute. The subnet management attribute can be configured with the signature bit string starting where the offset bits indicate, and the subnet management attribute can be included as an attribute of the InfiniBand compatible network device.

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 using queue pair 1 (QP1) for receiving multicast based announcements in multiple partitions in a high performance computing. In accordance with an embodiment, by extending the scope of QP1 to also include receiving and sending multicast packets in any partition defined for the port, it is possible to implement generic MC based announcement and discovery without requiring the complexity of unique QPs for individual partitions, nor any update of QP configuration as a consequence of change of partition membership.

Abstract: Systems and methods for supporting dual-port virtual router in a high performance computing environment. In accordance with an embodiment, a dual port router abstraction can provide a simple way for enabling subnet-to-subnet router functionality to be defined based on a switch hardware implementation. A virtual dual-port router can logically be connected outside a corresponding switch port. This virtual dual-port router can provide an InfiniBand specification compliant view to a standard management entity, such as a Subnet Manager. In accordance with an embodiment, a dual-ported router model implies that different subnets can be connected in a way where each subnet fully controls the forwarding of packets as well as address mappings in the ingress path to the subnet.
