[gmx-users] SEGMENTATION FAULT (Core dumped)

I try to launch the simulation with the line you wrote me Justin, but
unfortunately this fatal error appears:

Setting the total number of threads is only supported with thread-MPI
and Gromacs was compiled without thread-MPI

I worked on a HPC that is managed by another department in my
university, What do we have to say to them in order to compile gromacs
in the right way?
