Notes

This time the library is built as a shared library. You need to set LD_LIBRARY_PATH correctly (see samples).
LAMMPS_POTENTIALS environment variable will be set in samples and module (lammps/29Oct20/intel).
Build of QMMM was skipped this time (might be possible with QE 6.5).

Tests

We performed only unittests for this version. Current test suite (lammps-testing) is designed to run in the singularity container; this is not what we want.
- In case you found misbehavior, official samples under "examples" directory may be helpful to verify the issue.
Result of unittests (make test) were copied to Testing directory. 87 errors were found.
- Most of those errors seem to be minor numerical errors (error criterion is often too strict). Changing Intel compiler version (17, 19, 19.1) does not help.
- Result of "lattice" command (which is also used in unittest of reax/c) seems to be different between GCC and Intel versions. (see below)
- Following unittests shows large deviations from the reference.
  - 6 AtomStyles:AtomStyleTest.body_nparticle: quarternion value is wrong for only one case.
  - 64 MolPairStyle:coul_diel: forces(?) after "displace_atoms all random" are wrong. Random caused the issue?
  - 211 ManybodyPairStyle:lcbop PairStyle.plain: not sure what happens
- Following tests also showed large deviations. This may be caused by "lattice" command. At least in the case of reax_c, no significant deviations are observed when the coordinate is loaded with "read_data".

In unittest (such as reax/c), test coordinate is generated with "lattice" command.
