Hi all,
I'm trying to run the 12km CONUS benchmark.
I'm getting a segfault, but before that a warning that points are exceeding cfl=2. So it looks like it's just unstable, but I'd have assumed the benchmark was set up so that it would work?
This is using WRF 3.9.1.1. To run the benchmark I'm using the files from test/em_real, with data files from http://www2.mmm.ucar.edu/WG2bench/conus12km_data_v3/ over the top (e.g. replacing namelist.input). I had to modify the namelist to add
to the &dynamics section, but it is otherwise unchanged.
I'm then using:
This is under slurm so you can't see the process control but its on 8 nodes with 64 tasks per node = 512 cores/processes total. I did try smaller runs first with same result, but I can see there are benchmark results for 512 cores so seemed a reasonable place to start. Nodes have 64 cores with 128GB RAM.
