Three Dimensional Animation for Performance Debugging Utilizing Human Cognitive Ability

摘要

Visualization is a useful first step for performnace debugging. that is, performance tuning of a parallel program if it shows the balance between computation and communication. In visualizing performance data, it is important to exploit the human cognitive ability of recognizing slight differences in shapes, positions and velocities of familiar objects. We have prposed animation for performance debugging that utilizes this human cognitive ability. It animats performance data based on dynamic system modeling where the data is mapped to a dynamic system model, the model is simulated and the result of simulation is made visible in 3 dimensions.
