# Calcul Mathématique Libre / Free Computational Mathematics

## Location

All the activities will take place in the CIRM library. We use the conference room on the ground floor as main stage, and breakout space elsewhere in the library.

Beware that there may be occasional thieves around the CIRM. Do not leave valuables unattended.

If you are planning on taking a taxi to leave CIRM and seek to share it you can use the above link to synchronize with the other participants.

## Schedule

We have made the schedule voluntarily flexible to maximize opportunities for participants to discover the ecosystem, and reciprocally for developers to expose their systems. The general idea is to have short demos to give an overview of the ecosystem to all participants. And then a combination of free tutorials where we point participants to resources to explore according to their pace and taste, with support from instructors roaming around. And possibly guided tutorials or longer presentations in separate rooms. The schedule will be progressively refined according to the participants interest.

Notes:
- Participants are encouraged to skip the parts that are irrelevant to them (e.g. tutorials on material they already master) to engage into parallel collaborative activities such as coding sprints.
- The planning has been designed so that participants can use their free time to enjoy the beautiful surroundings; hence the long lunch break and late work.
