Abstract. This paper presents a tool setup for comprehensive eventbased performance analysis of large-scale openmp and hybrid openmp/ mpi applications. The kojak framework is used for portable code instrumentation and automatic analysis while the new Vampir NG infrastructure serves as generic visualization engine for both openmp and mpi performance properties. The tools share the same data base which enables a smooth transition from bottleneck auto-detection to manual in-depth visualization and analysis. With Vampir NG being a distributed dataparallel architecture, large problems on very large scale systems can be addressed.
Brunst and Mohr REF introduced a tool to analyze the performance for hybrid OpenMP and MPI programs.
