System and method for providing multicast group membership defined in relation to partition membership in a high performance computing environment

摘要

Systems and methods for providing multicast group (MCG) membership in relation to partition membership in a high performance computing environment. According to one embodiment, the SM is more efficient by allowing the subnet manager of the local subnet to be instructed to configure all ports that are members of the associated partition as members of a particular multicast group. A general multicast routing process can be executed. It is also possible to limit the interaction between the IB client and subnet management conventionally required to process join and leave operations. In addition, instead of creating a spanning tree after receiving each multicast group join request as previously required, create a spanning tree for routing multicast packets containing each partition member added to the multicast group. As a result, the overhead of the subnet manager can be reduced.
