[lammps-users] Asking for help

Dear LAMMPS users,
Since I’m new to LAMMPS, I don’t know how to run an example. With “mpirun” command, this error has occurred: “cannot connected to the local mpd” .
I typed “mpirun -np 4 lmp <in.colloid” and the error was the same as I said.
Would you please help.
Thank you beforehand.

This is an MPI problem, not a LAMMPS problem. Your MPI
is not installed/setup correctly. Likely you have not launched
the mpd daemon. Try reading its doc pages and
running test problems that came with your MPI.
