Related to neb.c:
In case that the OpenMP parallelism is disabled by adding
-Dnoomp as compiler option for CC and FC in makefile,
the patch should be applied.
Related to Band_DFT_kpath.c, Band_DFT_MO.c, Force.c, and Set_Orbitals_Grid.c
Variables were not properly assigned for the parallelization using OpenMP
in those routines, which may cause serious problems.
The problem will be resovled by applying the patch.
Also, there was a serious bug in Band_DFT_MO.c, which causes an incorrect output
of LCAO coefficients in *.out. The problem will be resovled by applying the patch.
Related to RestartFileDFT.c:
It seems that a deadlock sometimes happens in the MPI calculation when BullxMPI
is used as MPI library. The problem is resolved by applying the patch.
Related to EigenBand_lapack.c:
In some cases, it is possible that erratic noise appears in the band dispersion.
The problem is resolved by applying the patch.
Related to Set_Allocate_Atom2CPU.c:
In the MPI parallelization, two or more MPI processes are used for a system including
a single atom, the calculation may stop due to segmentation fault.
The problem is resolved by applying the patch.
