9th VI-HPS Tuning Workshop (UVSQ, France)

Date

April 23-27, 2012

Location

Université de Versailles
St-Quentin-en-Yvelines, France

Organizing Institutions

UVSQ

Goals

This workshop will:

  • give an overview of the VI-HPS programming tools suite
  • explain the functionality of individual tools, and how to use them effectively
  • offer hands-on experience and expert assistance using the tools
The workshop will be held in English and run from 09:00 to not later than 18:00 each day, with breaks for lunch and refreshments. There is no fee for participation, however, participants are responsible for their own travel and accommodation.

    Classroom capacity is limited, therefore priority will be given to applicants with parallel codes already running on the workshop computer systems, and those bringing codes from similar systems to work on. Participants are therefore encouraged to prepare their own MPI, OpenMP and hybrid OpenMP/MPI parallel application codes for analysis.

    VI-HPS Tools

    • KCachegrind is a free cache-utilization visualization tool developed by TUM.
    • MAQAO free modular assembly code quality analyzer and optimizer framework developed by UVSQ.
    • MUST & Marmot are free correctness checking tools for MPI programs developed by TUD-ZIH and partners.
    • PAPI is a free library interfacing to hardware performance counters developed by UTK-ICL and used by many tools.
    • Periscope is an automatic performance analysis tool using a distributed online search for performance bottlenecks being developed by TUM.
    • Scalasca is an open-source toolset developed by JSC & GRS that can be used to analyze the performance behaviour of MPI & OpenMP parallel applications and automatically identify inefficiencies.
    • TAU is a performance system for measurement and analysis of parallel programs written in Fortran, C, C++, Java & Python developed by the University of Oregon.
    • Vampir is a commercial framework and graphical analysis tool developed by TUD-ZIH to display and analyze trace files, such as those produced by the open-source VampirTrace library.

    Hardware and Software Platforms

    The local HPC system is expected to be the primary platforms for the workshop, with priority for improved job turnaround and local system support. Course accounts will be provided for those who need them.

    Other systems where up-to-date versions of the tools are installed can also be used when preferred, though support may be limited. Participants are expected to already possess user accounts on non-local systems they intend to use, and should be familiar with the procedures for compiling and running parallel applications on the systems.
