Abstract:   The theme of this BOF is the envisioned usage of future Exascale systems and the related challenges. In particular will address the following topics
  • How does Exascale computing improve the quality of numerical simulations? (larger models, finer meshes, ensembles, optimization/inverse problems, multi-physics, ...)
  • Which applications are ready to scale to Exascale (> 1-10 M cores)?
  • Where are the bottlenecks (scientific, algorithms, programming models, interconnect communication, memory/storage, I/O, ...)?
Speakers in the BoF are developers of highly scalable applications that today run on Petascale systems and target Exascale systems in the future. Thomas Gerhold from DLR and Vincent Moreau from CORIA will present the scalability challenges for aircraft CFD (TAU code) and turbulent combustion (YALES2 code). George Mozdzynski from ECMWF will cover the challenges of scaling their weather forecasting code IFS. Jesus Labarta from BSC will show how tools can help to identify and predict scalability issues.

Targeted Audience
The BoF targets application developers, algorithm designers, HW architects interested in the scalability challenge for Exascale.
