cclm_to_cclm
Hello,
I am attempting to run the nested experiment on a Linux machine using cclm-sp-1.3.4.
The job crashes due to a memory leak at the int2lm stage (over 100 Gb).
Any recommendations please.
Greetings, Simon
Hard to see from the output you attached. Can you provide the namelist file and “ncdump -h” results from
/Tmp_Research/CLIMAT/Giora/COSMO- CLM /cclm-sp-1.3.4/data/extem/domain2013111313023.nc
and
/Tmp_Research/CLIMAT/Giora/COSMO- CLM /cclm-sp-1.3.4/chain/work/me001/post/lffd1989010100c.nc
Dear Experts,
Attached please see the file with the information requested – when possible.
The is a problem — the file /Tmp_Research/CLIMAT/Giora/COSMO- CLM /cclm-sp-1.3.4/chain/work/me001/post/lffd1989010100c.nc has a problem.
The ncdump -h command ends with the following diagnostics “ NetCDF: unknown file format“
I have repeated all my steps on your test case for 2000. Again – the lffd .nc file in my /se001/post directory may not be open with our ncdump .
(I can see these files with ncview however !!!)
It must be noted that the gcm_to_clm runs ended successfully. I used the me001 (and sp001) modeling results for an analysis using CDO .
The problematic files are included in the tar file I am attaching.
Thanks and best wishes,
Simon
I have no problems with ncdump on lffd1989010100c.nc, see the listing below.
I checked the file with
ncks -m
see below, which gives information about the format. It says “chunked? yes, compressed? yes” which means that the file is in netcdf4 with hdf/zip library applied. I guess this was performed in the gcmtoclm job in the post.tmpl (you should find anccopy -d 1
or similar command there). It seems to me that you have problems with netcdf4 on your computer systems.Please check whether the command “nccopy -k 1 lffd1989010100c.nc tmp.nc” works (this converts netcdf4 back to classical netCDF format). If it works check whether “ncdump -h tmp.nc” works. If so, replace lffd1989010100c.nc by tmp.nc and run the model again. Please provide the log file of that test. If it takes this hurdle and stops at the next boundary condition file you really have a problem with netCDF4.

Dear Burkhardt,
There really was a problem – not exactly with the netcdf4 library but with compilation of the int2lm.
It seems to be ok now. Thank you very much for helpful suggestions.
Regards,
Simon
