[DFTB-Plus-User] Openmp vs. mpi

[Morteza Chehel Amirani]

Dear Bálint

I did a test to compare the performance of the openmp and mpi versions of
dftb+18.1. I run the same input file using 32 cores (on a single node) for
the openmp version and 96 cores for the mpi version. I got 58 MD steps from
the openmp and 62 steps from the mpi runs. I just wanted to know if this is
what you also expect from the two implementations? Thanks.

Sincerely,
Morteza
