Abstract
A method and apparatus for presenting the multiple processors of a cluster as a single virtual host to a network wherein the processors are communicatively coupled among themselves and to a network interface. The network interface is communicatively coupled to the network. One of the processors is designated a primary parallel I/O processor. One address is advertised on said network for said multiple processors, and filter trees in the network interface direct the interface to forward packets from the network addressed to that address to the primary parallel I/O processor. Later, the filter tree is modified to direct the network interface to forward a specific subset of the packets directly to a particular processor.
