Abstract
A method, system and computer program product are disclosed for maintaining data coherence, for use in a multi-node processing system where each of the nodes includes one or more components. In one embodiment, the method comprises establishing a data domain, assigning a group of the components to the data domain, sending a coherence message from a first component of the processing system to a second component of the processing system, and determining if that second component is assigned to the data domain. In this embodiment, if that second component is assigned to the data domain, the coherence message is transferred to all of the components assigned to the data domain to maintain data coherency among those components. In an embodiment, if that second component is assigned to the data domain, the first component is assigned to the data domain.
