[gmx-users] Re: A bug for MPI of GROMACS?

Chaofu,

What implementation of mdrun do you use? What system concretely do you
energy-minimize? What do you mean by saying "exploding of the
configuration into parts"?

It seems that the former one leads to obvious exploding of the configuration into parts whereas the latter one can obtain a reasonable configuration. Noted that the system is a polymer (dendrimer) without pbc. I wonder if this is a bug for MPI of GROMACS. Could you give me some hints? Thanks a lot for your attention!
