ERROR: Processor partitions do not match number of allocated processors (../lammps.cpp:254)

I am running NEB simulation with following partition command:

mpirun -np 8 /home/prasad/Packages/lammps-10Aug15/src/lmp_mpi -partition 8x1 -in in.neb

I am getting following error:

ERROR: Processor partitions do not match number of allocated processors (…/lammps.cpp:254)

FYI, I have 8 processor in my CPU.

Can you tell what is the problem?

This error could happen when the mpirun command is part of a different MPI package, than the one used to compile lammps. Can you please try the same command line on the melt example and post the screen output here.
