A propos du centre ou de la direction fonctionnelle

The Inria Grenoble - Rhône-Alpes research center groups together almost 600 people in 22 research teams and 7 research support departments.

Staff is present on three campuses in Grenoble, in close collaboration with other research and higher education institutions (Université Grenoble Alpes, CNRS, CEA, INRAE, …), but also with key economic players in the area.

Inria Grenoble - Rhône-Alpes is active in the fields of high-performance computing, verification and embedded systems, modeling of the environment at multiple levels, and data science and artificial intelligence.

The center is a top-level scientific institute with an extensive network of international collaborations in Europe and the rest of the world.

 

Contexte et atouts du poste

The successful candidate will join the AIRSEA team, a joint team between Inria, CNRS and Université Grenoble Alpes (UGA). The AIRSEA team is part of the Laboratoire Jean Kuntzmann (LJK) and located in Grenoble (St. Martin d'Hères) where also the working place will be.

The AIRSEA team (http://team.inria.fr/airsea/) carries out research work in applied mathematics and computer science for the modeling of oceanic and atmospheric flows.

The team is particularly active on four areas of research:

1) modeling oceanic and atmospheric flows
2) model / dimension reduction
3) managing uncertainties
4) designing and implementing numerical algorithms suitable for high performance computing.

Mission confiée

The recruited candidate will investigate domain specific languages (DSL) mainly for the CROCO ocean model ( croco-ocean.org ). This is a state-of-the-art coastal model which is used across the world, driven mainly by a French research community.

This will be at the intersection of several skills of the AIRSEA team such as discretization of ocean PDEs and high-performance computing. In addition, external DSL specialists and CROCO developers from Grenoble, France and other countries might be involved in this development.

The main goal is to use either a new or an embedded DSL with CROCO to support different HPC hardware and HPC optimizations which are transparent to the CROCO model developers.

For any questions, feel free to get in touch with me: martin.schreiber@univ-grenoble-alpes.fr

Principales activités

Main activities:

  • Getting acquainted to the CROCO ocean simulation development ( croco-ocean.org ).
  • Review existing domain specific languages (DSL) for ocean simulations.
  • The activities are split into three main parts:
    • Frontend: Either develop a DSL from scratch or use an embedded DSL for CROCO.
    • Middle layer: Work on transformations relevant for HPC optimizations
    • Backend: Develop support for one or more HPC architectures

Additional activities:

  • Write or contribute to a scientific publication for an international journal / conference
  • Potentially, present the work at international conferences / workshops
  • Take the NEMO development into account which is another ocean simulation code

Compétences

Essential

  • Software development experience in languages like Python, C/C++, or Fortran
  • Excellent communication skills and willing to work in a dynamic and collaborative environment

Desired

  • A PhD thesis in the field of computer science or mathematics
  • Knowledge of PDE solvers with finite difference methods
  • Knowledge of compilers or domain specific languages

Avantages

  • Subsidized meals
  • Partial reimbursement of public transport costs
  • Leave: 7 weeks of annual leave + 10 extra days off due to RTT (statutory reduction in working hours) + possibility of exceptional leave (sick children, moving home, etc.)
  • Possibility of teleworking (after 6 months of employment) and flexible organization of working hours
  • Professional equipment available (videoconferencing, loan of computer equipment, etc.)
  • Social, cultural and sports events and activities
  • Access to vocational training
