I am a new hire with GDIT on the WCOSS2 contract. I will be working with Peter Johnsen and Karen Haines. My main responsibility will be performance profiling and optimization of science applications. I have already ported hpc-stack and HAFS to my home system (Ubuntu-22.04). I don't have access to the NCEP platforms yet as I am going through the security process.

Can someone help me set up a small (c96 maybe) case so I can run on my workstation? Please reach out to me at Daniel.Kokron@noaa.gov

Hi，Dan,
You may start from regression test cases (e.g., HAFS_rt_regional_atm_only).
Best,

I don't see that script under my HAFS build. I also don't see "HAFS_rt" in any file under my build. The closest thing I could find is called "start_rt_auto.py".

I found rt.sh under HAFS/sorc/hafs_forecast.fd/tests. This appears to be the regression tests driver. It references numerous input files. Are these available from a public source?
rt.sh:INPUTDATA_ROOT=${INPUTDATA_ROOT:-$DISKNM/NEMSfv3gfs/input-data-20220414}
rt.sh:INPUTDATA_ROOT_WW3=${INPUTDATA_ROOT}/WW3_input_data_20211113
rt.sh:INPUTDATA_ROOT_BMIC=${INPUTDATA_ROOT_BMIC:-$DISKNM/NEMSfv3gfs/BM_IC-20220207}

Nevermind, I found them

My workstation has two EPYC Rome sockets each with 24 hardware cores. Can you help me set the following parameters in default_vars.sh?

You can try TPN=24.
