DescriptionThis tutorial presents state-of-the-art performance
tools for leading-edge HPC systems founded on the
community-developed Score-P 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 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 HPC Linux [http://www.hpclinux.org] OVA image
containing all of the necessary tools (running within a
virtual machine), participants will conduct exercises on
the Stampede system at TACC where remote access to Intel
Xeon Phi (KNL) nodes will be provided for the hands-on
sessions. This will help to prepare participants to
locate and diagnose performance bottlenecks in their own
parallel programs.
