Application scalability study using tools to analyze the parallel applications on the example of the atmosphere model NH3D

The article describes an approach to the scalability study using applications analyzing tools. This approach uses application profiling and tracing of the bottle necks for scalability analysis. There is a brief review of parallel program effectiveness marks, approaches to scalability study and performance analysis tools for parallel applications. This article performs detailed description of analyzing methodology and detailed review of parallel application that was analyzed using this methodology. Also in this article was performed the analysis results of described parallel application using profiling and tracing tools. For the analysis the authors used Intel Trace Analyzer and Collector as an example of tracing tool. In conclusion the authors admitted high level of analyzing features of this tool for scalability analysis purposes.
