Sparse Days Meeting 2011

Sparse Days Meeting 2011 at CERFACS
September 6th-7th, 2011

 

We are as usual holding our annual Sparse Days at CERFACS but there are significant building works at CERFACS in May and June and so we will hold this year’s Sparse Days in September, the week after the ParCo and Europar meetings.

As is our custom, we try to have a focus on a topical theme. The “in topic” this year seems to be discussing and formulating strategies for developing software, algorithms, and libraries for the Exascale computers anticipated in 2018-2020 so we particularly welcome any contributions addressing this issue. However, as always feel free to present your latest ideas and work on exploiting sparsity.


 Registration (Deadline : August 22th)

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 : August 22th)

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.

Trophy of the Digital Simulation and Artificial intelligence 2020 – Co design category

Jérôme DOMBARD |  27 October 2020

The "Usine Digitale" magazine and Teratec awarded the Digital Simulation and Artificial intelligence Trophy 2020 category co-design to our joint project about the first LES of a full engine with Akira Tech and Safran. More information on Acknowledgments: these results are part of the ATOM project led by SafranTech which received funding from the DGAC, French Civil Aviation Authority, and Safran under grant agreement No 2018-39.Read more


Young PhD day (JDD) – Thursday 8 October 2020

Brigitte Yzel |  24 September 2020

  Ph.D. Students' Day (JDD 2020) Thursday 8 October 2020 Virtual event open to our partners and associates   Planning   The 2020 edition of the PhD Students' Day will take place on October 8th, 2020. This year, this day of the PhD students of the Cerfacs, will take place mainly in visio in order to respect all the health safety measures relating to Covid-19. This day will be held in a virtual way through oral presentations filmed and broadcast on a private link, which we will distribute to all participants. Everyone will thus be able to discover at a distance the subjects developed by the doctoral students. At the same time, the "Posters session" will be opened on the morning of the JDD, by sending all the posters in pdf format by e-mail to all the participants for consultation, and by opening the "50-minute question session" on a channel whose links we will send you. This will allow participants to ask questions about the posters of the session. Finally, we have included in this 5th edition a great novelty, by allowing several students to present their subject in the popularised form of "My thesis in 3 minutes", guided by Matthieu Pouget, actor and theatre director. This day will end with the vote for the "Best poster" and the "Best presentation of My thesis in 3 minutes". Participation in the event is free of charge. However, for logistical reasons, registration, only by invitation, is mandatory.   Organising Committee:  Scientific committee  Nicolas Venkovic Victor Xing Inscription &  information Jade Schweiger Brigitte Yzel  Read more
