Archiving to MASS on xcm via moose in v7.3 UKCA CheT+GLOMAPnitrate

Description

I am trying to get a nitrate-UKCA job from the IBM MONSOON
running on the Cray MONSOON (xcm).

The job is my xlypa which is a copy of Claudia Steadman's
job xlsfe which she was trying to port across from her
original xlryc job from the IBM MONSOON.

The xlypa job now compiles OK and I think it is now completing it's reconfiguration OK. But it is failing with "mknod" error

qsexecute: mknod fails to create pipe to archiving system.

See on MONSOON the file:

/home/grmann/output/xlypa000.xlypa.d15312.t200950.leave

This sounds like an archiving error and probably because the
job was set to archive to the /nerc disk on the IBM MONSOON
but that no longer exists on the Cray MONSOON.

I am going to retry switching off the archiving to see whether
the job then runs OK.

But I guess what I need to do is set the job to archive instead
to MASS via moose. But I don't know how to set that up to
do so on xcm

I looked back at my emails as I recalled encountering this
particular error on ARCHER — and indeed I see Hannah Pearce
(PhD student at Leeds) had this error when she was first
switching on the archiving with the ARCHER-equivalent of this
v7.3-UKCA-GLOMAPnitrate job.

From the NCAS-CMS ticket 1580 it looks like Annette Osprey
advised on this:

http://cms.ncas.ac.uk/ticket/1580

and I see from Luke's porting notes on the UKCA website for
the v7.3 CheS job:

http://www.ukca.ac.uk/wiki/index.php/MONSooN_IBM_to_Cray_Transition

That in his xcm-ported xlsjf he uses a hand-edit from Annette:

~annette/hadgem3/hand_edits/new_archiving_std.ed

But I just did an ls on that and that file no longer seems
to exist.

I see in Annette's directory there is a file:

moose_archiving_new_cpl.ed

which has comment it is v7.3 MONSOON archiving.

Please can you advise whether or not I have found the right hand-edit there?

And also how one goes about activating that in a v7.3 job?

Does one also have to add in the hector_monsoon_archiving branch
or is that already taken care of via the hand edit?

Thanks for your help

Cheers
Graham

Hi Graham,

We have a section on archiving on the XCM for the various UM versions on the Collaboration Twiki:

Hi Ros,
Thanks

I just had a look at those pages.

I went through the bullet point list of items for the atmos-only
v7.3 job and those changes have all already been carried out in the job xlypa.

I think Claudia must have followed those instructions to set that up.

And those changes won't fix this mknod error.

As per my message it looks like Annette has a different branch/hand-edit than
the one used in the xlypa job — so maybe I need to use that — but as I say,
I don't know how to activate that in the job — just hand-edit or also a branch?

Cheers
Graham

Graham,

On that page there is also an archiving section, which lists the branch and hand-edit needed for vn7.3:

http://collab.metoffice.gov.uk/twiki/bin/view/Support/CrayUMInstall#Archiving

Luke has spotted an issue with archiving at 7.3 which means that climate mean files aren't being archived properly. We are looking into this.

Regards,
Annette

Hi Annette,
Oh right — sorry — don't know how I missed that.
I'll try that then.
