Frédérique Voisin-Demery

Short Presentation I was born in Limoges and I received my DEA in Applied Math - Parallel Computation from the Joseph Fourier University in 1996. I received my PhD in computer science from University Louis Pasteur (Strasbourg) in July 2001. I was working under supervision of Guy-René Perrin at the LSIIT, in the ICPS team.

Publications

• Sparse Computation with Pei, Frédérique Voisin, Guy-René Perrin, International Journal of Foundations of Computer Science Vol.10 No 14 (1999) 425-442
  It is a longer version of Sparse Computation with Pei, Frédérique Voisin, Guy-René Perrin, 6th International Workshop on Solving Irregularly Structured Problems in Parallel, San Juan, Puerto Rico, April 16, 1999, Proceedings of 11 IPPS/SPDP'99 Workshops, LNCS 1586, Springer-Verlag, 1999

  Abstract : Pei is a formalism which allows to express data-parallel programs : datas are mapped onto a geometrical domain and functions applied on the domain leads to data-parallel programs. We show that we can use this framework to obtain sparse formulations of dense programs.

• Minimisation des communications dans une résolution distribuée des équations de Navier-Stokes,Frédérique Voisin-Demery, Renpar'10, Strasbourg, France, Juin 1998

  Abstract : Solving the Navier-Stokes equations using a special formulation of the variables yields to a coarse grain parallization of the resolution. But one resolution step implies data communications that should be minimized.
