[DFTB-Plus-User] Regarding DFTB+ in parallel

[Hegoi Manzano]

Hi, 

I have compiled DFTB+ in a Dell x_64 machine with 4 processors each of them with 4 cores. I want to run the job in parallel using the 16 nodes that I have. Then, how should be the mpirun command? If I try

 mpirun -cpus-per-proc 4 ./dftb+

It works in 4 processors, but what about the 4 cores per processor? Are they being used? Sorry for my ignorance on the parallel issues, and thanks in advance.
