Einstein Toolkit Workshop 2015
Einstein Toolkit Workshop 2015
11-14 August 2015 AlbaNova


This workshop is centered around the new developments in open source infrastructure in numerical relativity and relativistic astrophysics. It aims to be an opportunity for current users and developers to report on recent progress in the Einstein Toolkit (including, but not limited to, new components), to express interests in future development, and to draw up a plan (collaborative as well as financial) to make sure this development takes place. The workshop will also feature an introductory session for new users, which will help to familiarize attendees with the Einstein Toolkit. We would also like to invite the local students from physics and computer science departments to participate.

Notice that this meeting will involve a few talks and status reports but will focus primarily on open discussions and planning.
