I run simulations using LAMMPS on the shared memory SGI UA system from my university. I need to run simulations by reading in restart files from previous simulations. But whenever I use the restart file no results files are outputted even the job has already run a really long time. The system shows the job is running but it also seems stuck somewhere and never really run. Below is the .o file outputted by the system when I stop my simulation and no other error messages showed up. It seems the simulation never really run after the processors are mapped.

Reading restart file …
WARNING: Restart file used different # of processors (read_restart.cpp:517)
orthogonal box = (-0.001 -0.001 -0.0126206) to (25.4806 24.4546 120.961)
2 by 2 by 9 MPI processor grid
If I read the data file to start the simulations there will be no such problem. I am not sure where the problem is. I will really appreciate if somebody can give some advice.
