About the research centre or Inria department
The Inria center at the University of Bordeaux is one of the nine Inria centers in France and has about twenty research teams.. The Inria centre is a major and recognized player in the field of digital sciences. It is at the heart of a rich R&D and innovation ecosystem: highly innovative SMEs, large industrial groups, competitiveness clusters, research and higher education players, laboratories of excellence, technological research institute...
Within the framework of the MAMBO project financed by the DGAC (French Civil Aviation Administration), Inria is recruiting a post-doctoral researcher within the CONCACE team for a period of 2 years at the Inria center at the University of Bordeaux. The objective is to continue and industrialize work from a previous PhD on the high performance solution of linear systems from aero-acoustics. As the CONCACE team is shared between Inria, Cerfacs (Toulouse) and Airbus Central R&T (Issy-Les-Moulineaux and Toulouse), travel will be possible between these sites (travel expenses will be covered within the limits of the current scale).
In the prolongation of Marek Felsoci's thesis, the candidate will be led to resume and extend this work devoted to the efficient solution of linear systems with dense and sparse parts. For dense linear systems, the most efficient approaches are based on hierarchical matrices (H-matrices https://www.theses.fr/2014PA132030 ) with low rank compression. For sparse linear systems, approaches based on nested dissection are used instead. The goal of this post-doc is to test two promising approaches:
- either use H-matrices for the whole dense+sparse system, using nested dissection on the sparse part ;
- or mix two different softwares (h-mat and qrm https://gitlab.com/qr_mumps/qr_mumps ) to treat the dense and sparse parts.
In all cases, task-based parallelism will be used via the StarPU runtime engine (https://starpu.gitlabpages.inria.fr/). The subject will be done in collaboration with the Airbus acoustics teams to validate the approaches on industrial cases.
Main activities :
- Bibliography and understanding of existing algorithms;
- Programming, testing, validation of new methods;
- Realization of industrial tests and scaling up in parallel;
- Writing documentation, scientific reports, research articles;
- Presentation in the framework of the MAMBO project and in scientific conferences.
Additional activities :
(if desired) teaching and managing interns
Technical skills and level required: 5 years or more of higher education or equivalent, master or engineering degree or PhD in applied mathematics or computer science with a scientific computing component.
Languages: the working language will be mainly French, but English will be used in exchanges with non-French speaking team members or collaborators.
Interpersonal skills: enjoy working and interacting in a collaborative research environment, curiosity and creativity.
Additional skills: writing scientific papers and public presentations of results.
