Abstract: System and method for correlating fabric-level group membership with subnet-level partition membership in a high performance computing environment. An exemplary embodiment can provide an admin partition in a subnet of a network environment, associated with a resource domain at the fabric level of the network environment. The admin partition can be defined by a P_Key that is stored in a fabric-level database. Each fabric resource is identified by an identifier that is stored in the fabric-level database. When fabric resources are added as members to the resource domain, a relationship is created between the P_Key and the identifier of the fabric resource, where the relationship defines the resource as a member of the admin partition. Access rights can be granted based on the relationship.

Abstract: Systems and methods of initiating virtual machine configuration on a subordinate node from a privileged node. An exemplary embodiment can provide a host channel adapter (HCA) including a control circuit with a processor and a memory, and a physical port operative to connect the HCA to a network fabric. Additionally, the HCA can include a subnet management agent (SMA) that executes on the HCA. The SMA can forward a request to register a virtual HCA to a subnet manager. The subnet manager can read an exposed attribute of the HCA, where the exposed attribute specifies the physical port as a privileged node, and where the value of the exposed attribute equals an assigned globally unique identifier (GUID) of the physical port. Upon receiving the request, the subnet manger can evaluate the GUID of the sending port to determine that the GUID and the value of the exposed attribute are equal.
