Numerical Methods and High Performance
Computing for Industrial Fluid Flows - SimRace

IFPEN, Rueil-Malmaison, 8 - 10 December 2015 - 1st edition



IFP Energies nouvelles organized SimRace, the first conference in the Rencontres Scientifiques series entirely devoted to numerical methods and High Performance Computing (HPC) for industrial fluid flows.

For many applied fields dealing with complex fluid flows, like petroleum basins or reservoirs, automotive or aerospace engines, refining processes, etc., there is today an increasing need for ever faster and more accurate simulations.

SimRace offered the opportunity to mix HPC and numerical analysis in a synergistic way, bringing together scientists and engineers and providing a melting pot of ideas and views between researchers, developers and end-users.
SimRace was the place to be for exchanging knowledge at the forefront of progress in both fields,
with a special focus on:

  • High-performance computational and programming models for emerging architectures
  • Scalable linear solvers
  • Numerical schemes on general meshes for complex flows
  • Multi-scale methods and model coupling
  • Challenging exaflopic applications

The SimRace International Conference was definitely be the right place for sharing on the challenge of designing new computational methods for exaflopic scale applications.


Special focus on

  • High-performance computational and programming models for emerging architectures
  • Scalable linear solvers
  • Numerical schemes on general meshes for complex flows
  • Multi-scale methods and model coupling
  • Challenging exaflopic applications

Oral presentations:

  • 45 minutes allotted for keynote speakers, including 5 minutes discussion
  • 25 minutes oral presentations, including 5 minutes discussion

Poster session

Poster will be displayed during a dedicated session and throughout the conference. The posters should be set up during all the conference.
The useful size of the poster board is 90 cm wide x 150 cm height max. Velcro tape will be provided at the welcome desk of the conference.

Industrial session

The industrial sponsors of the conference will have the opportunity to present their products during a dedicated oral session followed by a time for discussions.

Official language

English will be the official language. Simultaneous interpretation will not be provided.

Congratulations to Ranine Tarabay and Jean-Baptiste Whal from IRMA-University of Strasbourg, winners of the SimRace Award sponsored by Hewlett Packard Enterprise for their work on the software Feel++

Tuned your own simulator to demonstrate how you could make efficient use of emerging architectures: multi-GPU, multi-cores, etc. Showed your software engineering skills guaranteeing the sustainability of your simulator within the fast-moving computer architecture world.

Highlighted the original numerical schemes that you used in your simulator. The innovative nature of the scheme focused on various objectives: precision of results, low computational cost with equivalent precision, ability to handle complex meshes, etc.

Ensured a fair comparison of competing simulators, and all the entries were assessed on 5 nodes of the IFPEN ENER110 supercomputer. These nodes contained 80 Intel SandyBridge cores and 10 NVidia K20m accelerators. The test phase on the cluster took place during November.

As long as your simulation worked on ENER110, we gave you the opportunity to present your simulator in a short five-minute talk at the beginning of the conference and highlighted its originality, along with its computing performance.

Showed your talents and tried to win the SimRace award!
