The SunTune Application Performance Optimization Seminar

Time:        Tue May 29, 9:00 - Thu May 31 16:00
Location:   Aachen University of Technology (RWTH),
                  Lecture Hall of the Computing and Communication Center

Ruud van der Pas (Sun)


Have you always wanted to know more how to optimize a technical scientific application for a modern RISC microprocessor? Are you interested to learn about shared memory parallelization? Did you not yet find the time to really familiarize yourself with these topics?

If the answer is "yes" to these questions, this is your seminar to go to !

The 3 day seminar will be given by Ruud van der Pas, one of the performance specialists in the Sun European HPC team.It will focus on Sun's UltraSPARC processor family, but also provides information that is generally applicable.

The following topics will be covered in detail:

  • The memory hierarchy in RISC cache based systems
  • Sequential optimization techniques
  • The following Sun Forte Developer components:
    • The Fortran and C compilers
    • The Performance Library
    • The Debugger
    • The Performance Analyzer
  • Microprocessor and server architectures
  • Serial optimization techniques
  • Modulo Scheduling
  • Introduction into Parallelization
  • Short introduction into MPI on Sun
  • Shared Memory Parallelization
    • Data Dependency Analysis
    • Automatic Parallelization
    • Explicit Parallelization using OpenMP

Through hands-on sessions you will have time to experiment yourself with the information and techniques presented.

We do not assume a specific background in this area. Primarily anybody with an interest to learn more about the technical details of application tuning is more than welcome. It is helpful to have some practical programming experiences, but it is not a requirement.

Although there is no coverage of C++ and many examples are in Fortran and/or C, C++ programmers will certainly benefit from this course as well.

The seminar is open to Sun customers, partners and employees.


The seminar is organized in cooperation with the Aachen University of Technology (RWTH) and sponsored by Sun Microsystems. There is no seminar fee. All other costs (e.g. travel, hotel, and consumptions) are at your own expenses.
