-For these settings, the single interaction requires $NZ/2=6$ diagonalizations.  The total set of processes will be dived into subgroups, each of size `p*q=6`. Thus the number of subgroups will be `24/6=4`. Each submatrix will be decomposed in block-cyclic fashion among `p*q` processes as in 3D case.
