News



I have defended my HDR (Habilitation à Diriger des Recherches) in March 2018. The manuscript is available, as well as the slides of the defense.




photo-research Research and Projects

My research interests include parallel computing and scheduling, especially on heterogeneous platforms. For now, I am particularly interested by the problem of scheduling task graphs under memory and I/O constraints, the analysis of dynamic schedulers and the scheduling problems that appear on hybrid platforms.

Funded Projects

I am part of the ANR SOLHARIS project (2019-2023), and responsible for the "Scheduling" work-package. This project extends the ANR SOLHAR project (2013-2018), which aimed at studying and designing algorithms and parallel programming models for implementing direct methods for the solution of sparse linear systems on emerging computers equipped with accelerators. In SOLHARIS, we are mainly interested in scaling the strategies developed during the SOLHAR project to distributed platforms.

Software

memDAG is library that handles task graphs (DAGs) with memory information. It is for example useful to compute or estimate the minimal sequential memory of a given DAG (or tree) of tasks, to compute the maximal memory of a parallel DAG processing and to tests several scheduling algorithms. It also includes an SP-ization algorithm, that is, an algorithm that transform any graph into a Series-Parallel graph by adding synchronisation vertices and edges.

photo-teaching Teaching and Supervision

In 2019, I am teaching the course on Data Aware Algorithms of the "Master d'Informatique Fondamentale" at ENS Lyon.



In 2008, 2010 and 2012, I was in charge of the course on Scheduling of the "Master d'Informatique Fondamentale" at ENS Lyon.
During my PhD, I was responsible for the practicals of the course "Algo des Réseaux et de Telecoms". The material I made is still available here.
