Abstract: Within a distributed data processing domain including a requester data processing node and one or more target data processing nodes, an update synchronization of a domain information file as stored on each target data processing node with each domain information file including a local information file having local information an individual operation of the requester data processing node and a global information file having global information associated with a collective operation of all of the data processing nodes. First, the requester data processing node detects domain update information including local update information or global update information. Second, the requester data processing node synchronizes an update of the local information file or the global information file of each domain information file as stored on the target data processing node(s) based on the respective local update information or the respective global update information of the detected domain update information.
