Colloque Sparse Days 2012

Colloque Sparse Days 2012 au CERFACS, Toulouse
25-26 Juin 2012


The annual « Sparse Days at CERFACS » will take place on the 25th and 26th of June, just after the SIAM Applied Linear Algebra meeting in Valencia.

The Sparse Days meeting will be similar in format to previous years. No invited speakers and all talks in plenary session. As it is after the SIAM/ALA meeting, we might expect an emphasis on sparse linear algebra and its applications, but contributions on any aspects of sparsity are welcome. In particular, talks on sparse optimization and on data assimilation would fit well with some of the current research at CERFACS.

Registration (Deadline : April 30th)

As usual there will be no registration fee although you must register beforehand with Brigitte Yzel (Brigitte.Yzel@cerfacs.fr).

People wanting to speak should email Xavier Vasseur (Xavier.Vasseur@cerfacs.fr) with a title and abstract of up to one page in LaTeX or plain text. Normally talks would be for thirty minutes (including questions) but this could be negotiable (either way). We do not want to have parallel sessions so we will not necessarily be able to accept all submissions. A poster session will be available. Please let us know if you would prefer this mode of presentation.

Accomodation (Deadline : April 30th)

Some low cost accomodation is available but limited at Meteo residences. You should let us know as soon as possible whether you want to stay there. If you require assistance with accomodation you must let Brigitte Yzel know before the deadline: Brigitte.Yzel@cerfacs.fr.

Travel Information

Toulouse is well served by many airports in many European countries including direct flights from Amsterdam, Brussels, Frankfurt, Lisbon, London, Milan, Munich, and Paris. A complete list of airports reachable non-stop from Toulouse is given on the web site:

For people coming from Valencia, there is unfortunately no direct flights although several airports are served by both Valencia and Toulouse including the above mentioned airports so potentially one would require only one change. A map of airports directly accessible from Valencia can be found from the web site:

It is possible to travel from Valencia to Toulouse by train although the journey takes about nine hours. A train schedule will shortly be available from the web site:

Another possibility and potentially quicker is to drive although then staging your journey with a day in Barcelona might be best. When you register for Sparse Days, can you indicate whether you are interested in sharing a car. We can then put you in touch with others who wish to do this.
