Try separating your grompp run from your mpirun: You should not really be having the scheduler execute the grompp. Run your grompp step to generate a .tpr either on the head node or on your local machine (then copy it over to the cluster).
(The -p that the scheduler is complaining about only appears in the grompp step, so don't have the scheduler run it).
