During the development of parallel application programs or load balancing strategies, it is extremely helpful to have powerful and easy-to-use facilities to observe what is happening at run-time. For this purpose, a general framework for defining events and for recording and visualizing event traces is proposed. Data collected from interviews with application developers and system developers is used to identify a basic set of abstract event types that are meaningful in many different application contexts and that can be customized to fit individual needs. The object-oriented design of a class hierarchy that implements the event model is outlined. We expect that our framework can be a good starting point for the development of a portable library for the recording of events and of portable tools that make it easy to achieve flexible visualizations of the run-time behavior of parallel and distributed applications with load balancing.     «
