An integrated visualization framework for interprocessor communication using 3-D virtual space

As a parallel system employs more processors to become more complex, it is very hard to understand, evaluate, and tune the system without the aid of the performance information visualization. Many researchers have found that the criteria of good visualization usually include scalability, multiple views, context and user interaction. In spite of much research in performance visualization of a parallel system, only a few results are available which meet those criteria in an integrated fashion. The paper presents an integrated visualization framework satisfying those criteria for interprocessor communication using 3-D virtual space. The proposed framework is currently applied to a parallel system SPAX (Scalable Parallel Architecture computer based on Xcent-net) being developed by the ETRI (Electronics and Telecommunications Research Institute).
