It’s definitely off-topic, but I understand your frustration. I would begin with:
- Please Read This First: Guidelines and Suggestions for posting LAMMPS questions
- posting your submission script, properly quoted.
- Compile a recent version of LAMMPS with parallel support, otherwise what is the point of using HPC at all?
Tip: when you compile LAMMPS from the login node, you will have to load the modules that will also go in the submission script, eg openMPI, GNU or Intel compilers, etc. This is to ensure that the libraries present at the time of compiling match those at the time of execution.
