Thank you Paolo, I'll see what happens on my workstation.

I don't think this is true. Maybe the default behavior has changed when 
nothing is specified on the command line (-nd N), but if you specify the 
number of processors for parallel subspace diagonalization, the behavior 
should be the same, scalapack or no scalapack.
