HI!.
My name is Rainer. I am one of the module-/SW-maintainers
for the bwHPC-C5-project. "http://www.bwhpc-c5.de/en/index.php";
Since a couple of time we can't run Gromacs 2016.n on
our clusters. Here's one of the errors we received from
one of the users:
<snip>
I am using Gromacs on BwUniCluster for few months and I performed
molecular Dynamics Simulations without any problem until the end of
July. Since August, I cannot prepare the input file and if I prepare
them elsewhere, the simulation crash although it was the same that the
ones which perfectly worked few days before. It seems that I have not
such problem smaller systems with less atoms.
