LSCAAWARE = [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.
