Checking my installation via serial mode of testing

LAMMPS LAMMPS Installation
1

I have installed LAMMPS 02Aug 2023 version and now from the bench directory I am running the test cases. I loaded the environmental modules and the path where lmp_nompi is oocated, but it ended up with following:

/apps/lammps-2Aug2023/02082023/bench$ mpirun -np 4 /apps/lammps-2Aug2023/02082023/bin/lmp_mpi -in in.rhodo

However, I checked, liblammps_mpi.so.0 is located inside /apps/lammps-2Aug2023/02082023/lib folder.

Then why is it unable to detect?

Please suggest.

thanks

Because you have not augmented the LD_LIBRARY_PATH environment variable accordingly so that the shared linker can find it.
