Archer2 storage space and MetUM running requirements for PolarRES

Unified Model
#1

Yet another config question I’m afraid. I’m still working on producing my own ancillaries from high—resolution orography data for the Arctic and Antarctic but more work to do before I can get them into ancil format. In the meantime, I’ve tried to run Andrew’s Antarctic CORDEX simulations for December 2000 using the ancillaries , SST, SIC and forcing data that he already has, but keep stumbling up against ‘file not found’ errors. It first happened during the make ancils steps, which I was able to overcome because I have the ancils produced by Andrew’s previous simulations. However, I’m now getting the same error in the glm recon step, specifically “Failed to open file /work/n02/n02/shakka/cylc-run/u-co137/share/cycle/20001201T0000Z/glm/ics/glm_atmanl”. I’ve verified that the file is definitely there on archer – it’s almost like my account on pumatest isn’t able to ‘see’ the file system on archer – can you think of any reasons for this?

Best wishes,

Ella

In /work/n02/n02/shakka/cylc-run/u-co137/log/job/20001201T0000Z/Antarctic_CORDEX_0p11deg_ancil_orog/01/job.out
There is a message about a missing file.
Your file doesn’t really exist as a file: it’s a link. Specifically, it’s a link to qrparm.mask_igbp , which is itself a link to
/home/n02/n02/shakka/remaking_ancils/mask
and this is in the /home directory, so can’t be seen from the compute nodes.

It needs to be on /work , so perhaps you should make a directory on /work and put your files here?

Hi Dave, the symlink was me, but I hadn’t remembered that the compute nodes can’t see /home ! A rookie mistake. I’ll change that now.
Thanks,
Ella
