Abstract

A system for supervisor partitioning of client resources in a subnet communications environment includes a plurality of client nodes, each receiving an allocated set of resources determined by a central authority, which assigns resources to a supervisor key associated with each supervisor of the plurality of client nodes. At each of the client nodes, the allocated set of resources are partitioned using a local supervisor associated therewith, with each supervisor associating one or more resource keys with one or more resources allocated to the corresponding client node, and assigning the one or more resource keys to the one or more applications. The supervisor keys are configured so as to prevent a given supervisor from partitioning resources not allocated to the client node associated therewith. Following the partitioning, communication packets are issued from the one or more applications to a resource provider node without inspection by the corresponding supervisor.
