On-line Performance Analysis Tools for Paralell Programs in Frotran 90 and MPI

(BMBF-WTZ Project POL 98/011)

Project Goal

This project aims at developing on-line performance analysis tools for parallel programs based on Fortran 90 and MPI. The tools will use an OMIS compliant monitoring system, which is based on the OCM, but will be ported to the MPI message passing library.

The project is funded by the German and Polish state, respectively, in the framework of the WTZ programme (scientific and technical collaboration between Germany and Eastern Europe).

Project Group

• External Project Partner:
  Parallel Computing Group at Institute of Computer Science (ICS), Stanislaw Staszic University of Mining and Metallurgy (AGH), Cracow, Poland (Dr. Marian Bubak)
• Responsible at LRR-TUM: Roland Wismüller

Project Schedule and Milestones

• Jan - Jun 1999:
  • Adapt OCM to support the MPI parallel programming library.
  • Adapt OCM to other hardware and operating systems (esp. IBM/AIX, HP/HP-UX).
  • Integrate the support for the Fortran 90 programming language into the DETOP debugger.
• Jul - Dec 1999:
  • Define and implement extensions to OCM needed for performance analysis, especially
    • Compile a catalogue of requirements arising from the desired tool functionality.
    • Define a data format for event traces based on SDDF meta-format,
    • Implement the support for providing clocks, counters and event traces,
    • Implement fine grained measurements (on functions, loops, and statements).
• Jan - Jun 2000:
  • Design and implement an on-line performance measurement tool based on OCM and PATOP. Detailed work includes
    • Selecting and filtering of performance data by the user; possible performance data are e.g. the states of processes, communication overheads, and the usage of system resources,
    • Translation of measurement requests to the level of the OMIS interface,
    • User-selectable and adaptable displays,
    • Logging performance data for a subsequent analysis with the off-line tool.
• Jul - Dec 2000:
  • Adapt and extend the off-line performance analysis tool TATOO. This includes
    • Reading, filtering, and analyzing trace data,
    • Summary statistics displays and tables,
    • Extend the displays of TATOO with visualization modules designed by ICS-AGH (Gantt charts, scatter-plots, 3-D plots).
