The Inria Sophia Antipolis - Méditerranée center counts 37 research teams and 9 support departments. The center's staff (about 600 people including 400 Inria employees) is composed of scientists of different nationalities (250 foreigners of 50 nationalities), engineers, technicians and administrators. 1/3 of the staff are civil servants, the others are contractual. The majority of the research teams at the center are located in Sophia Antipolis and Nice in the Alpes-Maritimes. Six teams are based in Montpellier and a team is hosted by the computer science department of the University of Bologna in Italy. The Center is a member of the University and Institution Community (ComUE) "Université Côte d'Azur (UCA)".

 Nachos is  a joint project-team  between Inria and  the Jean-Alexandre Dieudonné Mathematics Laboratory at  University Nice Sophia Antipolis. The team  gathers applied mathematicians and  computational scientists who are collaboratively undertaking  research activities aiming at the design, analysis, development and  application of innovative numerical methods for systems of  partial differential equations (PDEs) modelling nanoscale light-matter interaction problems. In this context, the team is  developing  the   DIOGENeS  [https://diogenes.inria.fr/]  software suite,  which  implements  several Discontinuous  Galerkin  (DG)  type methods tailored to the systems  of time- and frequency-domain Maxwell equations  possibly coupled  to  differential  equations modeling  the behaviour of propagation  media at optical frequencies.  DIOGENeS is a unique  numerical   framework  leveraging   the  capabilities   of  DG techniques  for  the simulation  of  multiscale  problems relevant  tonanophotonics and nanoplasmonics.

 The  team is  involved in  a recently  lauched multi-partner  European initiative toward the establishment of a highly productive programming environment for heterogeneous exascale  computing. In this context our main  objective is  to  demonstrate that,  thanks  to the  programming models and software tools offered  by this environment, we can achieve highly scalable implementations of finite element type solvers for the simulation of  nanoscale light/matter interactions that  we develop in the framework of the DIOGENeS software suite.

 More precisely,  the successful  candidate will  be assigned  two main missions.   On one  hand,  he/she will  leverage advanced  programming models and environments  developed by other partners  of this European project in order to develop accelerator-enabled versions of DG kernels currently  exploited in  the DIOGENeS  software suite.   On the  other hand, he/she will contribute to  the implementation of innovative high order  finite element  type  solvers that  are  inherently adpated  to highly parallel systems.  This part of the work will also be conducted in close collaboration with Ph.D  and postdoctoral fellows of the team who  are  currently investigating  a  new  family of  highly  scalable multiscale finite element  solvers for the solution of  the PDE modelsrelevant to nanophotonics.

Candidates will  hold a Master degree or a PhD degree in applied mathematics/scientific computing.

Required skills:
- Sound knowledge of numerical analysis and development of finite element  type methods for computational physics;
- A concrete experience in numerical modeling for computational electromagnetics   will be an asset;

 - Strong programming skills and exposure to object-oriented model;

 - Knowledge and experience of Fortran 95/2000x;

 - Knowledge and experience of MPI, OpenMP and OpenACC;

 - Fluent spoken and written English.
