Dear Sir/Madam?,

After following the instructions to upgrade from phase 2b to phase 3 and submitting the job (ID: xhdta) I am receiving the following compiler error:

ftn-7991 crayftn: INTERNAL ASAD_CHEMICAL_DIAGNOSTICS, File = /home/n02/n02/dan2012/um/xhdta/ummodel/ppsrc/UM/atmosphere/UKCA/asad_chem_flux_diags.f90, Line = 8346

INTERNAL COMPILER ERROR: "unexpected type in TYPE_DEREF" (v_expr_obj.c 87117, line 751)

fcm_internal compile failed (256)

Any help on identifying the source of this error would be greatly appreciated.

Many thanks in advance for your time

Please give us permission to read files in your home space.

chmod -R g+rx /home/n02/n02/dan2012

and for future help it'll be convenient to have permission to read files in your work space too

chmod -R g+rx /work/n02/n02/dan2012

You can restrict read permissions to individual directories of course if you wish.

Hi Dan

The problem is a internal Cray compiler error, which will need to be fixed by Cray. But if you reduce the optimisation level to -O1 then it will compile fine. I have made a compile override file which I think will do this but it is untested so get back to me if it doesn't work. The file is


It needs to go in umui panel

Compilation and Modifications → UM User Override Files → User file overrides
