WRF v4.4 Benchmark Cases
Files for benchmarking were created with WPSV4.4 and WRFV4.4 (but can be used with any V4* WRF code).
Input data used was GFS 0.25 degree analysis.
The case used for the CONUS tests is the Pre-Thanksgiving Winter Storm of 2019.
The full test (original wrf simulation, and then restart) was completed for both an ifort and gnu
build of WRF.
The tar files listed below contain data and scripts for benchmarking purposes:
- Namelists set up to run a full WRF simulation, and then a 1 hour restart, as well as the namelist.wps for each case
- Boundary and initial conditions created by the real program
- A batch script used to run wrf for the original simulation and the restart simulation
- *.dat - data files needed for Thompson microphysics (these are usually generated during wrf, but takes a while to produce)
- diffwrf.py - script to compare original wrfout file with new wrfout file that will be generated with a restart simulation
- *.png - sample PNG files of acceptable differences
- README - with details about the cases and instructions for running the test and verifying results
- history and restart files created during the tests - can be used for comparison
- rsl.out.0000* - simulation log files for the original wrf simulation and restarts
