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: System and method for supporting flexible partition key (P_Key) mapping in a high performance computing environment. In accordance with an embodiment, when such computer environments comprise more than one subnet and/or forwarding domain that support inter-subnet partitions, the P_Keys comprising such inter-subnet partitions can change across domain boundaries. In such situations, a partition key of a packet can be updated upon entry to a new subnet and/or forwarding domain.

Abstract: System and method for supporting proxy based multicast forwarding in a high performance computing environment. In accordance with an embodiment, a proxy based multicast forwarding system and method can be utilized. A proxy, either software, firmware, or hardware based, can be initialized and run within a local subnet domain, wherein the proxy is a member of at least one multicast group (MCG). The proxy can be configured to forward packets to other subnet domains in several different methods.

Abstract: Systems and methods for initiating a forced migration of a virtual machine. An exemplary embodiment can provide a subnet manager (SM) and an active virtual machine registration cache, where the subnet manager can access the active virtual machine registration cache. The SM can record a first virtual machine incarnation number in the active virtual machine registration cache, where the virtual machine incarnation number is associated with an active virtual machine (VM). Upon receiving a request to register the active VM on a different host, the SM can evaluate a second virtual machine incarnation number with the first virtual machine incarnation number to determine the legality of the request. In accordance with an embodiment, if the second virtual machine incarnation number is evaluated as greater than the first virtual machine incarnation number, the SM determines the request is legal.

Abstract: System and method for supporting flexible forwarding domain boundaries in a high performance computing environment. In accordance with an embodiment, flexible forwarding domain boundaries can be supported by dividing/partitioning a physical switch into two or more logical switches, where each switch is logically in a different domain, and allowing a fabric to be decomposed into independent subnets with one two or more physical end ports at the physical switch. By doing so, the same hierarchical forwarding structure and management structure between subnets can be provided as when complete physical switches are used as building blocks.

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 to use all incoming multicast (MC) packets as a basis for global unique identifier (GUID) to local identifier (LID) cache contents in a high performance computing environment, in accordance with an embodiment. Since all multicast packets have a Global Route Header (GRH), there is always both a source GID and a source LID defined for an incoming multicast packet. This implies that it is, in general, possible for an HCA implementation to gather information about GID and GUID to LID mappings for any sender node based on all incoming MC packets.

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.
