SC'13 tutorial: Hands-on Practical Hybrid Parallel Application Performance Engineering (Denver, CO, USA)
Sunday 17th November 2013
- Markus Geimer, Jülich Supercomputing Centre
- Sameer Shende, University of Oregon
- Bert Wesarg, Technische Universität Dresden
- Brian Wylie, Jülich Supercomputing Centre
The tutorial takes place as part of the SC'13 conference in room 301 of the Colorado Convention Center, Denver, CO, USA. In preparation for the hands-on exercises, participants are encouraged to download the latest VI-HPS Linux ISO for execution within VirtualBox on their notebook computer.
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, OpenMP, hybrid MPI+OpenMP, and increasingly common usage of accelerators. Parallel performance evaluation tools from the VI-HPS (Virtual Institute High Productivity Supercomputing) are introduced and featured in hands-on exercises with Scalasca, Vampir 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. Using their own notebook computers with a provided Linux Live-ISO image containing the tools (booted from DVD/USB or within a virtual machine) will help to prepare participants to locate and diagnose performance bottlenecks in their own parallel programs.
Registration via the SC'13 conference website (or on-site) is possible with or without including the conference technical program, exhibition and workshops.
