The performance of parallel and distributed systems and applications - its evaluation, analysis, prediction and optimization - is a fundamental topic for research investigation and a technological problem that requires innovations in tools and techniques to keep pace with system and application evolution. This dual view of performance "science" and performance "technology" jointly spans broad fields of performance modeling, evaluation, instrumentation, measurement, analysis, monitoring, optimization, and prediction.

Most of the past and current research on performance analysis is focused on high-performance computing using dedicated parallel machines since performance is the ultimate goal in this environment. Future applications in the area of high-performance computing will not only use individual parallel systems but a large set of networked resources. This scenario of computational and data grids is attracting a lot of attention from application scientists as well as from computer scientists. In addition to the inherent complexity of program tuning on parallel machines, the sharing of resources and the transparency of the actual available resources introduce new challenges on performance analysis systems and performance tuning techniques. To meet those challenges, experts in parallel computing have to work together with experts in distributed computing. Aspects such as network performance, quality-of-service, security, heterogeneity, middleware systems, and object-oriented modeling - just to mention a few - will have a big impact on grid computing strategies.

Therefore, the seminar will bring together people from high-performance and distributed computing to discuss the impact of the following aspects on performance analysis for grid environments. The seminar will develop perspectives for performance oriented program development not only in scientific computing but also in commercial distributed computing. The workshop is scheduled for the week before Euro-Par in Paderborn ( to allow people to attend both events.

Topics to be covered include:

  • Performance analysis tools and techniques for parallel computers
  • Performance tools for distributed applications
  • Network performance measurement and quality-of-service
  • Performance models
  • Performance data requirements of
    • adaptive algorithms, e.g. caching schemes for web services and video streaming as well as load balancing techniques
    • scheduling and resource management techniques
    • accounting for grid environments
  • Standard formats for performance data and protocols for accessing performance data
  • Automation techniques for the performance analysis process
  • Security requirements for performance analysis systems
  • Integration of performance analysis and performance tuning

Dagstuhl-Seminar Series


In der Reihe Dagstuhl Reports werden alle Dagstuhl-Seminare und Dagstuhl-Perspektiven-Workshops dokumentiert. Die Organisatoren stellen zusammen mit dem Collector des Seminars einen Bericht zusammen, der die Beiträge der Autoren zusammenfasst und um eine Zusammenfassung ergänzt.
