    How different?  If the difference is only a few places past the decimal point, it could be due to floating point calculations on different processor architectures.  If the difference is more significant, it could be due to a change in LAMMPS.  Is your PC version the same as the LAMMPS version you selected in lammpstool?  By default the tool runs 22Aug18.

        That depends on what commands you are using in your lammps script.  The HPC versions that run on nanoHUB may be linked against different libraries.
