Practical Hybrid Parallel Application Performance Engineering
Date: Sunday, June 22, 2014, 02:00 PM - 06:00 PM
Room: Seminar Room 14/15 CCL - Congress Center Leipzig
Description: This tutorial presents state-of-the-art performance tools for leading-edge HPC systems founded on the Score-P community-developed instrumentation and measurement infrastructure, demonstrating how they can be used for performance engineering of effective scientific applications based on standard MPI, OpenMP, hybrid combination of both, and increasingly common usage of accelerators. Parallel performance tools from the Virtual Institute – High Productivity Supercomputing (VI-HPS) are introduced and featured in demonstrations with Scalasca, Vampir, Periscope and TAU. We present the complete workflow of performance engineering, including instrumentation, measurement (profiling and tracing, timing and PAPI 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. The knowledge gained in this tutorial will help participants to locate and diagnose performance bottlenecks in their own parallel programs.
