Welcome to my personal page!

Welcome. This page summarizes various professionnal and non-professionnal activities. I hope you'll find useful things in it.

What I look like

Name and age

My name is Arnaud Legrand and I'm 48.

Family

I have a wonderful wife named Sophie and five sons: Clément, Rémi, Loïs, Élouan and Gabriel. Two of my sons are also engaged into academia: Clément and Rémi.

Occupation

I am a CNRS research director at the LIG and I am a happy member of the Anthropocene Degrowth and ICT project! I have worked in the INRIA MESCAL project from 2004 to 2015 and I have been the leader of the INRIA POLARIS project from 2016 to the end of 2025. From 2021 to 2025, I have been a member of the Section 6 of the CoNRS.

I used to be a PhD. student at the LIP (Parallel Computing Lab.) located in the École normale supérieure de Lyon under the supervision of Yves Robert and Olivier Beaumont. I also made a postdoc at UC San Diego where I worked with Henri Casanova, Larry Carter and Jeanne Ferrante. Once I was even a Master intern there and I worked under the supervision of Henri Casanova and Fran Berman.

Here is my curriculum vitæ.

Research Interest

My research targets the management (mostly from an algorithmic point of view, i.e., scheduling, load balancing, fairness, game theory….) and performance evaluation (in particular through simulation, visualization, statistical analysis, …) of large scale distributed computing infrastructures such as clusters, grids, desktop grids, volunteer computing platforms, clouds,… when used for scientific computing. In particular, I am one of the main developers of the SimGrid project.

Please check the corresponding page for more details.

Hobbies

Reading good books, snowboarding, longboarding, rollerskating, playing piano (both classical music and jazz, especially with my sons), hacking LaTeX, using org-mode and R, writing perl scripts… in short: kind of a geek :o)

Getting in touch with me

This section describes how to contact me, but please bear in mind that I do have a private life, involving a family and little kids. So, before you call me on my private line, reconsider the urgency of your request. Can't that wait until Monday? Isn't it possible to drop me an email instead? If we need to set up an audio or a physical meeting, you should check in my professional agenda first.

Emails

This is the much preferred way of communication (for professional contacts, I mean). Drop me an email, and you're sure you won't disturb me in any way. I'll deal with it as soon as I can. That's really the best for me.

My professional email is arnaud.legrand@imag.fr
