fregrid error: FATAL Error: nxgrid is greater than MAXXGRID/nthreads, increase MAXXGRID, decrease nthreads, or increase number of MPI ranks #208

Thanks, with that simple change (fregrid to fregrid_parallel, see below) this works for us. Is it safe to make this our default choice for all resolutions?

@StevePny Last week there was an upgrade to master that was mostly a documentation upgrade. You may want to clone it (or just read the docs online) as its got a couple of items related to this. Mostly its in the extreme fregrid pdf in the docs directory. Assuming you don't have any issues, and given the new docs, and assuming you don't have any issue with that, I am closing this question. Please let me know if you disagree. Thanks. |
Hi I'm getting this error when trying to combine the diagnostic file output from fv3-shield when running at C768 resolution (this works for us at the other resolutions):
We've tried moving to a bigger memory machine (an aws ec2 instance with ~1000GB of memory), we've tried running with the max number of processors (64), and we've also tried rebuilding the package with MAXXGRID set to 1e10 in create_xgrid.h. We've also tried using the remap files generated by UFS_UTILS. We're only able to combine the files to a 1-degree resolution. We'd like to be able to combine at the original or at least at 1/4-degree resolution.
Here are some examples of our run commands:
We'd like a workable solution for combining these files at the C768 resolution into a single global netcdf file.
