cxil_map: write error with real.exe

[avipwrfhelp]

Hello,
I have been getting this error repeatedly with WRF (v4.1.3, 4.2.2) built with intel mpich on sapphire-rapids. I think I saw this issue on the forum but with nested domains on derecho but this is a large single (CONUS) domain. Also, I checked the floor on minimum number of processor cores when running this. Attaching my nameless.input and rsl.error.0000 file.

Thanks for any suggestions.

Hi,
Are you using the standard NCAR-managed WRF? I'm asking because the error message that prints out is

cxil_map: write error

and I can't find anything related to "cxil" in the WRF code. If so,

1) Have you made any modifications to the code?
2) Can you try this with V4.6.0 and see if the problem still exists?
3) Make sure you have enough disk space to write the large files from real.exe
4) Please package all rsl* files into a single *.tar file and attach that (if it's too large, see the forum home page for instructions on sharing large files).

Hello,

the source was obtained from https://github.com/wrf-model/WRF/
1) and no mods were made to the code.

Please see the ticket

Running WRF Domain Configuration on Derecho That Was Stable on Cheyenne​

dated 5/1/24, where this "cxil_map: write error" was also mentioned and where apparently the suggested solution was the domain decomposition on a nested domain, but this is one large domain.

The tarred up rsl.* files are attached.

Hi,
Apologies for the delay. I don't have access to that ticket. Our group is not part of the CISL support group. We only work with the WRF model. This does seem to be something specific to the system or environment setup, though. If you have all your files in a directory on Derecho, would you mind sharing that with me? I can test it out on my end, and I may end up having to point you to CISL support, but I can at least try it first.
