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.

Teaching
In 2019 and 2020, I have given the course on Data Aware Algorithms of the "Master d'Informatique Fondamentale" at ENS Lyon. A short version of this course has been taught as a mini-course for PhD students at the University of Varsaw in 2023. 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. |
