MUMPS User Group Meeting

Toulouse
15, 16 April 2010

Presentation

The MUMPS team is organizing a MUMPS User Group Meeting on April 15th and 16th 2010 at ENSEEIHT, Toulouse. This will be the second edition of a series of meetings started with the 2006 MUMPS User Group Meeting. The aim of this event is to bring together experts both from academia and industry. The general theme of the meeting is sparse direct solvers and related issues, ranging from applications to experiences with MUMPS (MUltifrontal Massively Parallel Solver) and other direct solvers, and combinatorial ingredients of sparse direct solvers.

Registration

The registration deadline for the MUMPS User Group Meeting is March 15th. To register, please send an email to any member of the organizing committee specifying name and affiliation.
Due to the nature of the meeting, only a limited number of slots are available for presentations. If you are willing to give a talk please contact the organizers.
