Hello,

My geogrid (V4) is failing to finish. The log shows it getting to step 26/31 (urban data) and then nothing after that. I'm not sure what's happening, the output from the job doesn't provide too much information. I get MPT errors, but everything I run on cheyenne has those errors, so I am not sure if that's the cause. Would it be better to post my files here or point to them on cheyenne? At one point a wrfhelp specialist was able to run my namelist.wps on his own install of geogrid and it completed.

Thanks!

Hello,

My WPS directory is "/glade/work/gbromley/programs/WPS* " . Submission scripts are in there as well as the logs and job output files.

Thanks!

I noticed that you're trying to run the geogrid program in parallel using 72 MPI tasks, but it looks like the WPS was actually compiled for serial execution; note these lines in your configure.wps file:
Code: 
#
#   Settings for Linux x86_64, Intel compiler    (serial)
#

It also looks like the geogrid program is getting to the point of processing the FRC_URB2D field. The dataset for this field is about 16 GB, so it could take quite a while to process in serial. Generally, geogrid only reads and processes tiles of data that are needed to cover the WRF simulation domain, but in your case, your domain covers quite a large geographical area, so it's likely that nearly all of the 16 GB of data would need to be processed for FRC_URB2D.

Cleaning, reconfiguring, and compiling the geogrid and metgrid programs for parallel execution may help in reducing the processing time; but, you may also need a longer wallclock limit for the geogrid job in any case.
