A consortium of MUMPS users is managed by

MUMPS User Days 2013

Clamart, near Paris, France
Wed 29th to Thu 30th of May 2013
Clamart, la Fourche


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 2013 MUMPS User Days were the third edition of the series. We thank EDF who co-organized and welcomed this event.
