Hands-on practical hybrid parallel application performance engineering

摘要: 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 engineering of effective scientific applications based standard MPI or OpenMP now common mixed-mode hybrid parallelizations. Parallel evaluation from Virtual Institute --- High Productivity Supercomputing (VI-HPS) are introduced featured in hands-on exercises with Periscope, Scalasca, Vampir TAU.We cover all aspects practice, including instrumentation, (profiling tracing, timing hardware counters), data storage, analysis visualization. Emphasis is placed combination identifying problems investigating optimization alternatives, illustrated a case study using major application code.
