2012

  • Nov 30, 2012:
    The MIDAS'09 project officially ended on November 30, 2012. We would like to thank all of those who contributed to its success. We of course hope to continue working on all new ideas, which have emerged during the fruitful and stimulating 3 years of the project. We will also keep on using the tools and algorithms developed by the project, as well as maintaing the publicly available, middle-layer CMB library, MIDAPACK, which we will continue distributing via this site.
  • Nov 30, 2012:
    Frédéric Deauvergne has concluded his work for the MIDAS'09 project. Frédéric worked on the development of the MIDAPACK library and in particular on the implementation of its Toeplitz algebra module Frédéric will continue as a software engineer with Maison de Simulation (CEA, INRIA, CNRS, Université Paris-Sud et Université de Versailles - St Quentin).
  • Nov 30, 2012:
    Mikolaj Szydlarski has finished his postdoctoral appointment with the MIDAS'09 project. During his time with the project Mikolaj has developed the GPU-compliant version of spherical harmonic transforms (distributed as part of the S2HAT software) as well as a new set of preconditioner for map-making software in the CMB context. This latter work has been presented during the Supercomputing'12 conference in early November. Mikolaj's next post is with Maison de Simulation (CEA, INRIA, CNRS, Université Paris-Sud et Université de Versailles - St Quentin).
  • Oct 31, 2012:
    Pierre Cargemel has concluded his post with the MIDAS project. During his year with us he has worked on the (de)projection operations and communication patterns for map-making problems developing new exciting approaches to these problems. He is now becoming a graduate student and University of Nice and French Petrol Institute.
  • Oct 22-25, 2012:

  • Sep 19-21, 2012:
    MIDAS'09-supported workshop 'Big Bang, big data, big computers' - on computer science and statistics of the contemporary CMB data analysis' was held at the APC Laboratory in Paris. MIDAS'09 work and results were highlighted in three talks by MIDAS'09 collaborators (Grigori, Sharify, Szydlarski) and three posters (Cargemel, Dauvergne, Fabbian). The meeting was met with huge interest by the community with an attendance of nearly 80 researchers restricted by the size of the conference room.
