Abstract: System and method providing resource access control within a single partition in a network switch environment in a high performance computing environment. A resource request portion of an IB packet includes data identifying a resource request for a requested resource, and a context identification portion of the packet includes data identifying a context of the resource request. Access rights to a controlled resource are determined based on the requested resource relative to the controlled resource and according to a comparison of the context of the resource request relative to one or more valid request context values. A resource table storing valid Q_Key and P_Key context values may be indexed by a Dest. QP of the packet header to determine selective access to the controlled resource and/or to data relating to the controlled resource.

Abstract: System and method for using multiple global identification subnet prefix values in a network switch environment in a high performance computing environment. A packet is received from a network fabric by a first Host Channel Adapter (HCA). The packet has a header portion including a destination subnet prefix identifying a destination subnet of the network fabric. The network HCA is allowed to receive the first packet from a port of the network HCA by selectively determining a logical state of a flag and, selectively in accordance with a predetermined logical state of the flag, ignoring the destination subnet prefix identifying the destination subnet of the network fabric.
