Since domain decomposition can not be used, I was trying to launch mdrun with the -ntmpi 1 -ntomp=number-of-cores options as Justin stated in an old discussion (https://mailman-1.sys.kth.se/pipermail/gromacs.org_gmx-users/2014-September/092341.html). However, the program gives me this error:

GROMACS needs to be compiled with thread-MPI support, and you can always
install your own version of the code within your home directory without
