Bridging Performance Analysis Tools and Analytic Performance Modeling for HPC

Abstract

Application performance is critical in high-performance computing (HPC), however, it is not considered in a systematic way in the HPC software development process. Integrated performance models could improve this situation. Advanced analytic performance modeling and performance analysis tools exist in isolation but have similar goals and could benefit mutually. We find that existing analysis tools could be extended to support analytic performance modeling and performance models could be used to improve the understanding of real application performance artifacts. We show a simple example of how a tool could support developers of analytic performance models. Finally, we propose to implement a strategy for integrated tool-supported performance modeling during the whole software development process.KeywordsMessage Passing InterfacePerformance ToolSoftware Development ProcessTarget ArchitectureCritical BlockThese keywords were added by machine and not by the authors.
