No you're not.  Frontends are important for systems like IBM BlueGene/Q where 
you cannot access the compute nodes at all directly, the batch script has to 
launch on a frontend node (which users may not be able to access) and then 
srun has the job of communicating with the BGQ control system to launch the 
executable on the compute nodes.

I've only ever heard of frontend nodes in the way that they're used on BGQ; 
what you are calling frontend nodes get called login nodes around here. :-)

All the best,
