LSCALU = [logical]
Default: LSCALU = .FALSE.
Description: LSCALU switches on the parallel LU decomposition (using scaLAPACK) in the orthonormalization of the wave functions.
For LSCALU=.TRUE. the LU decomposition in the orthormalization of the wave functions is done in parallel, using scaLAPACK routines. Provided, of course, LSCALAPACK=.TRUE. and VASP was compiled with scaLAPACK support (precompiler flag: -DscaLAPACK).
