Research and Design of a Remote Visualization Parallel Program Performance Analysis Tool

摘要

Parallel program performance analysis plays an important role in exploring parallelism and improving efficiency of parallel programs. A remote interactive parallel program performance analysis tool based on dynamic code instrumentation is designed on the basis of analysis and comparison of existing program performance analysis tools. A hierarchical structure is adopted by this tool which consists of 3 parts: client, server and computing nodes. Performance analysis tasks are submitted to the server via the graphical user interface of the client, and then actual analysis processes are started on the computing nodes by the server to collect performance data for visualization in the client. The performance information gained by this tool is comprehensive and intuitive, so it is quite helpful for users to analyze performance, locate bottlenecks of programs, and optimize programs.
