Benchmark Cases
===============
Benchmark cases are available for :ref:`v44` and :ref:`v422`.
|
.. _v44:
WRFv4.4
=======
Files for benchmarking are created with WPSV4.4 and WRFV4.4 (but can be used with any V4* WRF code).
* Input data : `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 with both an ifort and gnu build of WRF.
* The tar files listed below contain the following data and scripts for benchmarking purposes:
* **namelist.input** (x2) - set up to run a full WRF simulation, and then a 1 hour restart, as well as the *namelist.wps* for each case
* **wrfbdy_d01** and **wrfinput_d0\*** - 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 files** - data files required for Thompson microphysics (these are usually generated during WRF, but take a while to produce)
* **diffwrf.py** - script to compare the *wrfout* file generated by the initial simulation with the *wrfout* file generated by the restart simulation
* **\*.png files** - sample PNG files of acceptable differences
* **README** - A text file including details about the cases and instructions for running the test and verifying results
* **wrfout\*** and **wrfrst\*** files - history and restart files created during the tests - can be used for comparison
* **rsl.out.000\* files** - simulation log files for the original WRF simulation and restarts
