Hi

The preliminary release announcement text is up at

http://einsteintoolkit.org/about/releases/ET_2016_11_announcement.txt

If you want to add/remove/change something, either go ahead yourself, or let me know directly. All developers should have write access to

https://svn.einsteintoolkit.org/www/about/releases/ET_2016_11_announcement.t...

Also let me know if you don't, and you would like to have access.

Release status --------------

We still have one worrying problem: the BSSN constraints can sometimes be wrong, resulting in test failures in the thorns Dissipation and RotatingSymmetry90/180. We are not sure what 'sometimes' really depends on. Indications are that most failures happen with Intel 15, but some are apparently also seen with Intel 16, while others with Intel 16 seem to work fine. Optimization -O1 instead of -O2 seems to prevent the problem, but is not a viable workaround. A simple 'print' statement in the affected (auto-generated) code also makes the problem disappear. Running using one MPI process and one openMP thread reproduces the problem. valgrind does not find anything obvious pointing to memory mess-up.

Peter Diener is working on the problem: please contact him if you like to help.
