Abstract
A method and a system for processor nodes configurable to operate in various distributed shared memory topologies. The processor node may be coupled to a first local memory. The first processor node may include a first local arbiter, which may be configured to perform one or more of a memory node decode or a coherency check on the first local memory. The processor node may also include a switch coupled to the first local arbiter for enabling and/or disabling the first local arbiter. Thus one or more processor nodes may be coupled together in various distributed shared memory configurations, depending on the configuration of their respective switches.
