GROMACS version: 2020.2  
GROMACS modification: Yes/No  
Hi GROMACS users.  
I’ve tried to energy minimization simulation with my system. But when I prompt command ‘top’, my machine used only one thread’ with mdrun -ntomp 4 option as from the user manual.  
I want to implement energy minimization step more faster.  
In my machine, openmpi-4.0.2 was installed and cpu with 12 thread and one gpu . How can I implement more faster minimization step with openmpi?

Thank you :)
