Developing Scalable Applications with Vampir, VampirServer and VampirTrace

Abstract

This paper presents some scalability studies of the performance analysis tools Vampir and VampirTrace. The usability is analyzed with data collected from real applications, i.e. the thirteen applications contained in the SPEC MPI 1.0 benchmark suite. The analysis covers all phases of performance analysis: instrumenting the application, collecting the performance data, and finally viewing and analyzing the data. The aspects examined include instrumenting effort, monitoring overhead, trace file sizes, load time and response time during analysis.
