Hi everybody,
I tried to run a minimization just of the hydrogen of a membrane protein.
I want to do this in vacuum.
But when I started the run with
mpirun mdrun_mpi -deffnm protein -v -nt 2
I get the error that there is a segmentation fault.
Threading and MPI parallelization are independent. You can't use both. If
you've compiled with MPI support, you can't invoke the -nt option.
But when I only type
mpirun mdrun_mpi
there is no problem so I guess that my already produced input files are
the problem. For example I am not completely sure about the .mdp file. Can
you please give me an example for a .mdp file for a minimization of only
the hydrogen but not the whole protein in a vacuum.
It would be far more useful for you to post what you're using so we can provide
feedback. The fact that the second command works while the first fails should
lead to the opposite conclusion - your input is fine, but your invocation of
mdrun was incorrect.
