Abstract: A display of CPU utilization in a multiprocessor system is provided. This feature illustrates processor utilization and application group assignments to CPUs and clusters of CPUs. Various graphic indicator are described that can be used to display processor utilization and indicate processors that have no application group assignments. For example, bar graphs as well as gauge displays can be used to visually convey processor utilization. As a result, a user can visually determine the processor utilization and application group assignments across a multiprocessor system. Additionally, various colors and shadings can be used to visually convey application group assignments.

Abstract: A data processing system includes a digital computer that has a plurality of data processing programs. A set of upgraded stations is coupled to the computer which generate messages that employ a relatively simple format to select the data processing programs; and a set of older stations is also coupled to the computer which generate messages that employ a complex format to select the data processing programs. A message routing program in the computer receives all of the messages from the stations, analyzes each message that has the simple format to identify the selected data processing program, and sends the message directly to the selected program. By comparison, the message routing program sends each message that has the complex format to a secondary routing program; and this secondary routing program analyzes each message which it receives, identifies the selected data processing program, and sends the message to the selected program.
