Presentation
The 2023 MUMPS User Days were the
fifth edition of the series.
The MUMPS User Days 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 event is coorganized by Théo Mary,
Fabienne Jezequel
(PEQUAN, LIP6, Sorbonne University)
and Chiara Puglisi (Mumps Technologies).
Please note that remote connection to the event will not be possible.
