MUMPS User Days

June 1-2, 2017
Montbonnot Saint-Martin
(near Grenoble, France)

MUMPS is a MUltifrontal Massively Parallel Solver


The MUMPS team organizes the MUMPS User Days (list of participants) on Thursday, June 1st and Friday, June 2nd 2017 at Inria, Montbonnot. This will be the fourth edition of a series of meetings started with the 2006 MUMPS User Group Meeting and continued in 2010 and 2013. The aim of this event is to bring together MUMPS users from both academia and industry and MUMPS developers. The general theme of the meeting ranges from sparse direct solvers and related issues to applications and experiences with MUMPS.
