ILAENV for ?getrf

[pghysels]

Hi,

When I call (mkl from fortran)

NB = ILAENV( 1, 'DGETRF', ' ', 4000, 4000, -1, -1 )

it always gives NB=1. For other methods it seems to work ok (DGEQRF gives NB=128).

I don't want to use mkl's getrf. I'm running Intel(R) Math Kernel Library 11.0 Update 5 for Linux* OS.
