The First International Workshop on Representative Applications was held September 8th in Chicago, USA as part of IEEE Cluster 2015. With 9 technical papers and a keynote presentation by Dr. Michael Heroux, the workshop provided a venue for attendees from across the world to learn about and discuss the use of represenattive applications in advancing computer science and computational science research. Below are full details of last year’s program.

 

  • 09:00–10:00 Making Representative Apps Represent Apps, Dr. Michael Heroux.

Representative Apps play a very important role design space exploration. If well designed and implemented they provide a distilled model of some aspect of real applications, providing much simpler target for computer system designer to address. Furthermore, representative apps can be re-designed and implemented in many settings, giving guidance on how future real applications can be recast.

In this presentation, we give a brief history of representative apps, provide some guidance on how to design and implement them and talk about some of our latest work in this area. We draw upon experiences from the Mantevo and HPCG benchmark projects in order to provide concrete examples.
