Hi, gromacs started dying on me lately with rather obscure error messages as in the caption of this mail. Errors seem to be related to the nvidia driver (see below for more output,and further below for the mdp file) ... i perform a large number of short (2ns) sims and this happens perhapsone ou

Hi Justin, thanks for the reply and the good idea. I checked a configuration of my system using both force fields and, for the information of anyone who may have a similar problem in the future, found using gmx energy: CHARMM36 from Tom Piggot on GROMACS website: Energy Aver

Hi, the most likely issue is that your GROMACS installation is not configured for the correct architecture; e.g. if the compute or login node that the cmake configure/compilation was done on is newer than the one that's running on, mdrun will try to issue instructions that are not supported by the
