Abstract
This tutorial presents state-of-the-art performance tools for leading-edge HPC systems founded on the Score-P community instrumentation and measurement infrastructure, demonstrating how they can be used for performance engineering of effective scientific applications based on standard MPI or OpenMP and now common mixed-mode hybrid parallelizations. Parallel performance evaluation tools from the Virtual Institute – High Productivity Supercomputing (VI-HPS) are introduced and featured in hands-on exercises with Periscope, Scalasca, Vampir and TAU.We cover all aspects of performance engineering practice, including instrumentation, measurement (profiling and tracing, timing and hardware counters), data storage, analysis and visualization. Emphasis is placed on how tools are used in combination for identifying performance problems and investigating optimization alternatives, illustrated with a case study using a major application code.
