LSCAAWAVE = [logical] 

Default: LSCAAWARE = .TRUE. if VASP is compiled with scaLAPACK support (precompiler flag -DscaLAPACK)
= .FALSE. otherwise

Description: LSCAAWARE decides weather to distribute the Hamilton matrix or not.


For LSCAAWARE=.TRUE., VASP distributes the Hamilton matrix and uses scaLAPACK routines to diagonalize subspaces.
