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.
