Hi Lammps-users,

I am trying to run the neb example, but i become this ERROR message:

mpirun -np 2 lmp_mpi -partition 2x1 -in in.diffusion

##

ERROR: Processor partitions do not match number of allocated processors (../lammps.cpp:260)
ERROR: Processor partitions do not match number of allocated processors (../lammps.cpp:260)
-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[51984,1],0]
  Exit code:    1
##

what am i doing wrong?

​the fact you you get two error messages is worrisome. there should be only one. do you get four, if you use mpirun -np 4?
if yes, it means, that either your lmp_mpi executable is not compiled for use with MPI, or that your mpirun command belongs to a different MPI library than what lmp_mpi was compiled with (e.g. MPICH vs. OpenMPI vs. IntelMPI vs. MVAPICH)​.

axel.


 

thanks,
