Welcome to my personal page!

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

Name and age:

My name is Arnaud Legrand and I'm 38.


I am a tenured CNRS research scientist at the LIG (formerly ID Laboratory). I work in the INRIA MESCAL project.

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.

If you're a student looking for an internship, please check the corresponding webpage.


Reading good books, snowboarding, rollerskating, longboarding, 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.


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

In case of emergency

I often read my mails, so even if you are in a hurry, emails may be a good guess.

Instant messaging systems

I use quite a bunch of those systems (thanks to pidgin). It should be safe to use this mean to contact me since I cut it when I can't afford to be disturbed.
