A method in a computer network having a first plurality of nodes coupled to a common network infrastructure and a distributed shared memory distributed among the first plurality of nodes for servicing a first memory access request by a first node of the computer network pertaining to a memory block having a home node different from the first node in the computer network. In one embodiment, the communications system includes a microphone or instrument pickup and an in-ear monitoring system. The probes may comprise a reporter molecule and a quencher molecule. The disclosed plasma-etch resist rework method can be a fast, simple, and cost effective process used in either single or dual damascene tri-layer patterning processes for the fabrication of, for example, sub 45-nm node semiconductor structures.
