Hi again, Natalie: You can look at a small, UK-region-only version of the suite ` ~/roses/u-da046m_UK` that has the `wlight_lyr` output variable. Patrick ---

Hi Patrick, Thanks! ‘wlight\_lyr’ was an accepted output variable when I changed JULES\_REVISION=‘27124’ to JULES\_REVISION=‘’ as in the suite you mention. I am still currently running my suite with batch = background (I know, smack my hand) but I haven’t figured out how the correct directives to join the short-serial-4hr-queue with batch = slurm. I don’t think this information appears in your u-da046m\_UK suite. Thanks again, Natalie ---

Hi Natalie: I’m glad you got it working! You correctly figured out that the latest JULES FORTRAN code for that branch is obtained by using JULES\_REVISION=‘’ instead of JULES\_REVISION=‘27124’. Running in the background might be ok, if it only takes a few minutes and you’re not doing parallel processing. I looked at your suite.rc file `~ndouglas/roses/MultiSite-PMcGuire-SIFMIP-MERRAvn3/suite.rc`. You have lines there commented out for `short-serial-4hr`. They look approximately right, except I think that `--ntasks = 8` might try to make this a parallel job, but `short-serial-4hr` is not a parallel queue/partition. It is a serial queue/partition. Also, you can’t use the `--constraint = "intel"` for `short-serial-4hr`, since that partition/queue doesn’t have any intel nodes. If you want to use the `short-serial-4hr` queue, then you can get rid of that constraint. If you want to use an intel node for this, then you can use the `short-serial` queue instead. Also, the intel/MPI libraries and modules listed in your env-script in that suite have been updated by the JASMIN team. Look at the latest version of the JULES FLUXNET suite u-al752 for the proper settings (see the file `u-al752/site/suite.rc.CEDA_JASMIN` ). The main reason for the update was that the JULES linking didn’t work when switching between intel and amd nodes. There might have been other updates since your old version, too. Patrick ---

Thank you, Patrick! I will investigate this as there are some things here that I don’t completely understand yet and would be valuable if I did. Natalie ---
