Abstract:As the development of high-performance computing, the requirement for debugging is not only limited in “correctness debugging”, but also for “performance debugging”, which means to achieve the best performance through program tuning. The correctness debugging and the performance debugging are usually supported by the separate tools, which couldn't sufficiently support high-performance computing. A visualization tool is presented in this paper that supports both “correctness debugging” and “performance debugging” for a high performance SIMD chip. This tool incorporates the functionality of debugging, the behavior monitoring and the performance analyzing. It greatly improves the development cycle of high-performance computing programming.
