WRAp 2018: in conjunction with IEEE Cluster 2018

Held as part of IEEE Cluster 2018, the Third International Workshop on Representative Applications is concerned with the development and use of representative applications (such as mini-applications or proxies) for all aspects of high-performance computing.

The challenges posed by future systems: new architectures, programming models, and machine scales; mean that representative applications as an essential tool in the path towards exascale. These applications can be used for acceptance testing, benchmarking, optimization evaluation, and also investigating the performance of new architectures or programming models. However, the development of such representative applications must ensure they maintain some correspondence with their parent application. Maintaining that correspodence requires methods and tools for identifying the performance critical aspects of a given code, or class of codes, and also for verifying that the proxy accurately models the the target behavior.

The main aim of WRAp is to provide a venue in which the wide range of disciplines involved in creating and using representative applications can share important discoveries and lessons learned from these applications.

We encourage submissions on all aspects of the design, creation and use of representative applications, including (but not limited to):

  • Programming model and language explorations.
  • Design and generation of representative applications.
  • New representative applications.
  • Verification and validation of representative applications.
  • Optimizations, including algorithmic improvements and code optimization.
  • Scalability studies.
  • Hardware studies.
  • Case-studies of representative applications impacting their parent code.

Work which examines similar topics will also be considered for inclusion in the workshop.


Authors are invited to submit full papers with unpublished, original work of not more than 8 pages of double column text using single spaced fonts on pages of 8.5 x 11 inches (this limit includes all figures, content and references). All papers should be formatted according to the IEEE Cluster guidelines as published here.

All accepted papers (subject to post-review revisions) will be published in the IEEE CLUSTER Conference Proceedings, provided that at least one author is registered for the conference.

Papers should be submitted using EasyChair here

  • Paper submission: 15th July 2018.
  • Author notification: 29th July 2018.
  • Camera-ready submission: TBA.

Workshop attendees must register for the main IEEE Cluster 2018 conference. Registration is currently closed, but this webpage will be updated once registration opens.
