A consortium of MUMPS users is managed by

MUMPS User Days 2017

Montbonnot Saint-Martin, near Grenoble, France
Thu 1st to Fri 2nd of June 2017
Montbonnot et Dent de Crolles


The MUMPS team organizes from time to time the MUMPS User Days. These are events which aim at bringing together MUMPS users from both academia and industry and MUMPS developers. The general theme of these meetings ranges from sparse direct solvers and related issues to applications and experiences with MUMPS. It is also a great opportunity for informal exchanges and discussions between users and developers of MUMPS.

The 2017 MUMPS User Days were the fourth edition of the series.
