Dear QE users,

             I have installed successfully QE. While running ./run_example,
I am getting the following error message,

  executables directory: /home/muj/DFT_software/qe-6.3/bin

It seems that there is no lamd running on the host MUJR3.

This indicates that the LAM/MPI runtime environment is not operating.

environment.  See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.

         Anyone can help me to get rid of this. I don't understand what to
do.

Thanks,

Regards,

Vipin
