The Exaflow project was presented by Philipp Schlatter and Erwin Laure at ISC 2016 in Frankfurt, in a workshop entitled: "Form Follows Function - Do algorithms and applications challenge or drag behind the hardware evolution?". The workshoplasted several hours during the afternoon, and drew an audience of about 25 people. Among the speakers were Jack Dongarra, Mark Parsons, Peter Messmer and Marie-Christine Sawley, representing both academia and industry (Intel, Bull-ATOS, Nvidia). Interesting discussion on different approaches about algorithms and hardware developments took place, in line with some of the basic aspects of the Exaflow project.

As part of the initial dissemination activities of ExaFLOW the Automotive Simulation Center Stuttgart organized on the 23rd of February the exclusive workshop “Simulation Driven Design for Computational Fluid Dynamics” in Leinfelden-Echterdingen (near Stuttgart) in Germany.  The workshop was focusing the trend of embedding CFD software into the automotive design process. Amongst other questions it adressed the following:

  • Is this trend only a part of the long-lasting frontloading process or is it a paradigm shift? Who are the key roles to enable the change? 
  • How much methodological knowledge needs an engineer?
  • How do we handle the conflict of objectives: the need of less system understanding by using a black box software or solving advanced problems by detailed understanding of solver algorithms?
  • Which are important aspects for industrial usage: real-time, automated, easy-to-use, CAD-embedded, bi-directional, multi-physics enabled?

The first face-to-face meeting of the ExaFLOW project team took place at the KTH Campus in Stockholm, Sweden on October 28th and 29th 2015. Over these two days the vision and mission of the project were revisited as well as the ways to move forward. The eight members of the project consortium team agreed on a number of managerial issues. All Work Package leaders presented the work to be done and detailed the tasks in further action points. All project deadlines have been reviewed for both internal and official deliverables.

Members from KTH, the University of Southampton, Imperial College London, MacLaren Racing, the Institute of Aerodynamics and Gasdynamis of the University of Stuttgart and the Automotive Simulation Centre of Stuttgart demonstrated together the use cases and codes which they are bringing into the ExaFLOW project. Discussions with PDC - Center for High Performance Computing at KTH, the High Performance Computing Centre of the University of Stuttgart and the Edinburgh Parallel Computing Centre of the University of Edimburgh on possibilities and limitations of deployments on supercomputing systems followed. As a result, initial requirements were discussed for the four use cases – McLaren front wing; NACA4412; jet in crossflow; automotive use case in cooperation with ASCS.
