LSCAAWARE
LSCAAWAVE = [logical]
| Default: LSCAAWARE | = .TRUE. | if VASP is compiled with scaLAPACK support (precompiler flag -DscaLAPACK) |
| = .FALSE. | otherwise |
Description: LSCAAWARE controls the distribution of the Hamilton matrix.
For LSCAAWARE=.TRUE., VASP distributes the Hamilton matrix among the MPI ranks. For LSCAAWARE=.FALSE., each MPI ranks allocates the complete Hamiltonain. In both cases LSCALAPACK decides if ScaLAPACK routines are used for diagonalization.
