A consortium of MUMPS users is managed by

MUMPS User Days 2010

Thu 15th to Fri 16th of April 2010
Toulouse, La Garonne


The MUMPS team organizes from time to time the MUMPS User Days.

The 2010 MUMPS User group meeting was the second edition of a series of meetings started with the 2006 MUMPS User Group Meeting. The aim of this event was to bring together experts both from academia and industry. The general theme of the meeting was 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.
