Abstract

This paper presents a tool setup for comprehensive event-based performance analysis of large-scale openmp and hybrid openmpmpi 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 data-parallel architecture, large problems on very large scale systems can be addressed.
