TheWRFV3.4.1.TAR.gz distro includes the two files

    WRFV3/phys/module_mp_wsm3_accel.F
    WRFV3/phys/module_mp_wsm5_accel.F

that are written to work with PGI Accelerator.
I tried the configuration

       30.  Cray XT CLE/Linux x86_64, PGI compiler with gcc  (dm+sm)

and made these changes to theconfigure.wrf

    CPP      =  /lib/cpp -C -P $(TRADFLAG)*-D_ACCEL -DACCEL*         #
    Not sure how the mangling is done.
    FCFLAGS  =  $(FCOPTIM) $(FCBASEOPTS)*-ta=nvidia -Mcuda=4.0,cc20
    -Minfo=accel*

but got these errors

    wsm32d:
         279, Accelerator region ignored

         371, Accelerator restriction: unsupported operation: RSQRTSS

Can any of you send me a configure.wrf and a list of build instructions 
that will work for this?
I'm running on a Cray.
Thanks,
