cray-netcdf(3):ERROR:105: Unable to locate a modulefile for 'cray-netcdf/4.4.0'

Reported by: laurahb Owned by: um_support
Component: UM Model Keywords:
Cc: Platform: ARCHER
UM Version:


I'm getting the above error message when I try to run my suite (u-ay059). I've found a couple of tickets with the same issue and they were advised to change this to
in the suite.rc file. However my suite.rc file doesn't have cray-netcdf/4.4.0 in it so I'm not sure where I should add these lines (I assumed I'd be replacing a similar line).

Hi Laura,

Your suite is set up differently to the examples you found (yours is now the norm). All Archer specific settings are in the site/archer.rc file.

Thanks, that seems to have fixed it.
However, I'm now getting a problem that it's timing out in the atmos_main step. I tried increasing the wallclock time from 2 to 3 hours but it still timed out. Does that mean it's getting stuck somewhere? Presumably since it's a standard job it should run within the specified time?

  • Platform set to ARCHER

Hi Laura,

It has run out of disk space on ARCHER:

sys-122 : UNRECOVERABLE error on system request 
  Disk quota exceeded

Encountered during an I/O operation on unit 6
Fortran unit 6 is connected to a sequential formatted text file:

So if you can delete some files you can continue your run. Longer term you may need to ask for an increase in quota.

Thanks, this was because I increased the wallclock time further after submitting that ticket, and it ran (so presumably it did just need more time), but then I got the disk quota issue. As this is the first thing I've run, I have basically no files stored on ARCHER: is it meant to put the output in /home/n02/n02/lbaker/cylc-run/u-ay059/ or is there somewhere else that I should set it to go that has more space?

Hi Laura,

The output of the compute nodes will end up in /work/n02/n02/lbaker/u-ay059. Rose will pull back a subset of this to your PUMA cylc_run directory to support diagnostics.

Grenville and Ros are currently away at meetings but will be able to increase your ARCHER quota if necessary.

In the mean time could you

chmod g+rX /work/n02/n02/lbaker
chmod g+rX /home/n02/n02/lbaker

This will help us if there are future issues.

Also please check your PUMA quota: use quota -v

Sorry that should be

chmod -R g+rX /work/n02/n02/lbaker
chmod -R g+rX /home/n02/n02/lbaker

Hi Laura,

I can sort out your ARCHR quota - you currently have very little. How much space are you likely to need?


comment:8 Changed 3 years ago by laurahb

Hi Ros,
Thanks for offering to increase my quota.
I don't have a very good sense of how much space I'll need… I plan to run (initially) 100 10-month simulations and will need monthly fields for all months and daily fields for 3-4 months of this (daily fields I need should just be surface fields). You probably have more of an idea than me of how much space this would need. If that's a lot then I can run in smaller batches and move stuff locally before running the next batch.

Just following up on this… please let me know if the information above is not enough and I can try to do some estimations of how much space I'm likely to need.

I have increased you quota to 1TB - let's see how you get on.
