Abstract
A method, apparatus, and computer instructions for broadcasting information. A change in data used by a number of processors in the data processing system is identified. A message is sent to the number of processors in the data processing system in which the message is sent with a priority level equal to a set of routines that use the data in response to identifying the change. This message is responded to only when the recipient is at an interrupt priority less favored than the priority of the message. A flag is set for each of the number of processors to form a plurality of set flags for the message in which the plurality of set flags are located in memory locations used by the number of processors in which the plurality of set flags remains set until a response is made to the message.
