[gmx-developers] Difference between GMX_MPI and GMX_LIB_MPI

[Xingcheng Lin]

Hi,

I have some difficulty differentiate the difference between GMX_MPI and
GMX_LIB_MPI. Both of them are used some where in Gromacs code. They seem to
be the same. But for thread-mpi it disables GMX_LIB_MPI without disabling
GMX_MPI. Can anyone tell me the difference between these two?

Thank you,
