...and what should one deduce from such obscure statements?
The important pieces of information here are:
- total number of MPI processes
- number of processors in the "linear-algebra" group, as
   specified by the -ndiag or -northo keyword. This is a square
   integer, and should be set to whatever gives the fastest
   diagonalization time, not to the maximum number
