SunHPC Workshop

Introduction

Have you wanted to know more about how to optimize a technical, scientific application for a modern RISC microprocessor? Are you interested in learning about parallelization? Now is the time to learn!

We will focus on serial program tuning, as well as tuning shared and distributed memory parallel applications using automatic parallelization, OpenMP resp. MPI. No background knowledge in these topics is assumed. We will cover the basics as well.

The general philosophy of the workshop is to build up understanding of key concepts that are relevant to obtain good application performance. Once this is achieved, it is much easier to use the development environment in the best possible way.

The Sun compilers, the Sun performance analyzer and the Sun HPC ClusterTools environment (MPI) will be covered in detail. It will be shown how these tools can be used to get optimal performance out of UltraSPARC IV and Opteron based Sun workstations and servers.

We will also briefly touch upon several third party software products, which augment the programmer's tool suite on the Sun systems.

This year's workshop will contain a shortened introduction into MPI. Instead we want to put more emphasis on shared memory parallelization. Thus we are including an in depth introduction into the ParaWise toolkit, a software product for automatic parallelization of "real-world" serial Fortran codes developed by Parallel Software Products Inc.(PSP). Experts from PSP will be on site to give an introduction and guide through a hands-on experience using ParaWise.

Participants

Attendees should be comfortable with C or Fortran programming and interested in learning more about the technical details of application tuning. Although there is no special coverage of C++ and the examples are in Fortran and/or C, C++ programmers will certainly benefit from this course as well.

Prepared lab exercises will be made available to participants. These exercises have been selected to demonstrate features discussed in the presentations. Participants who prefer to work on their own application(s) instead will be welcome to do so. A suitable preparation of Makefiles and small plus medium sized data sets are of course desirable in this case.

The workshop language will be English.

SunHPC Consortium Meeting

Introduction

The HPC Consortium is a Sun Global Education and Research worldwide customer forum which meets to research and discuss high-end scientific and engineering computing issues and trends. While the Consortium is primarily a technical computing user group meeting for Sun's academic and research customers, customers and interested parties from industry and government are welcome.

The Aachen meeting will particularly focus on developers' interests. Thus we invite participants to profit from the unique opportunity to also take part in the SunHPC workshop in order to learn more about optimization and parallelization and gather hands-on experience.

Keynote Presentation

The UltraSPARC(TM) T1 processor is the first aggressive CMT (Chip-MultiThreading) design from a major computer systems vendor. The US T1 contains 8 cores each capable of handling 4 threads. By running 32 threads simultaneously on one chip, impressive performance is achieved on targeted parallel workloads. At the same time, by keeping the clock rate low, power consumption is significantly reduced. This leads to an excellent performance/watt metric. This talk will cover the architecture and performance characteristics of the UltraSPARC T1 processor and the Sun Fire T1000 and T2000 systems.

Partha Tirumalai is a Distinguished Engineer in the Scalable Systems Group of Sun Microsystems. He has been with Sun since 1993 working on the architecture, compiler, and performance of UltraSPARC processors. Prior to joining Sun, he was a research scientist at Hewlett-Packard Laboratories working on advanced processor architecture. Partha has a B.S. degree in EE, and M.S. and Ph.D. degrees in Computer Science.

Travel Information

Please make your own hotel reservation through the Aachen tourist service.

Please, download a sketch of the city (pdf, 415 KB) with some points of interest marked.

You may find a description of how to reach us by plane, train or car here.

Bus route 33 connects the city and the stop "Mies-van-der-Rohe-Straße" every 15 minutes.
Trains between Aachen and Düsseldorf stop at "Aachen West" station which is a 5 minutes walk away from the center.
From the bus stop and the train station just walk uphill the "Seffenter Weg". The first buildung on the lefthand side at the junction with "Kopernikusstraße" is the Computing Center.

The weather in Aachen is usually unpredictable. At that time of the year the temperatures will be most likely between 10 and 15 degrees Celsius. It is always a good idea to carry an umbrella. If you'll bring one, it might be sunny!
