cula_device_dpbtrf - Argument 1 is invalid

[kyperros]

Hi,

I am trying to use subroutine cula_device_dpbtrf through PGI fortran. I keep receiving the following error status:

"Argument 1 is invalid"

Argument 1 is a character and probably is not passed correctly to CULA.
I get the same error using cula_dpbtrf.

How could i overcome this problem?

Opereating system: Winfows 7 x64
PGI Visual Fortran 2010
CULA R17
CUDA 6.5
NVIDIA GTX 570

Thank you.
