Problem to start running HadGEM3

[demory]

Hi

I took a copy of Pier Luigi's job (xgtwf) to make a 1-day test at N512 (in xgylb). I don't want to recompile, so I am using PL's executable. I get an error that I have never seen before:

sys-2 : UNRECOVERABLE error on system request

No such file or directory

Encountered during an OPEN of unit 6
Fortran unit 6 is not connected

I didn't manage to get more information than that, even from the core file. I looked into the code, and it seems that unit 6 might be the file "CONFIG" (from clfhist.h but I might be looking at the wrong file). Do you know what this is?

Best wishes,

Hi Marie-Estelle,

I'm not sure what is causing this error but one thing you could try is to use the scripts from Pier Luigi's job. Since you have not compiled you will by default be using the central run scripts which may not have all the changes required for your job.

Either you can build the scripts:

Go to Compilation and Run Options → UM Scripts Build
and then select "Enable build of UM scripts"

Or just copy over the bin/ directory from the original job.

Reply from Marie-Estelle:

Dear Annette,

Thank you very much, your solution has fixed the problem indeed!! So but does that mean that it is preferable to always recompile a model we take from someone else? So that, if I understand well, the UM scripts will be built properly?

Thanks a lot again!

Glad this worked!

Generally speaking if you use an executable from another job you should have "Enable build of UM scripts" turned on. This doesn't actually compile the model, it just sets the scripts up properly from the branches you have turned on in the job.

Best wishes,
Annette
