Vampir 10.6 provides an easy-to-use framework that enables developers to quickly display and analyze arbitrary program behavior at any level of detail. The tool suite implements optimized event analysis algorithms and customizable displays that enable fast and interactive rendering of very complex performance monitoring data.

The combined handling and visualization of instrumented and sampled event traces generated by Score-P enables an outstanding performance analysis capability of highly-parallel applications. Current developments also include the analysis of memory and I/O behavior that often impacts an application's performance.

Score-P is the primary code instrumentation and run-time measurement framework for Vampir and supports various instrumentation methods, including instrumentation at source level and at compile/link time.

Vampir and Score-P provide a performance tool framework with special focus on highly-parallel applications. Performance data is collected from multi-process (MPI, SHMEM), thread-parallel (OpenMP, Pthreads), as well as accelerator-based paradigms (CUDA, HIP, OpenCL, OpenACC).
