MUMPS User Group Meeting

May 29th and 30th 2013

MUltifrontal Massively Parallel Solver


The MUMPS team organizes a MUMPS User Group Meeting (list of participants) on Wednesday 29 and Thursday 30 May 2013 at EDF, Clamart. This will be the third edition of a series of meetings started with the 2006 MUMPS User Group Meeting and continued in 2010. 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 and other direct solvers, and combinatorial ingredients of sparse direct solvers.
