Testing for NetCDF, C and Fortran compiler
This installation NetCDF is 64-bit
C compiler is 64-bit
Fortran compiler is 64-bit
Your versions of Fortran and NETCDF are not consistent.
```bash
If the compile successfully,
there should be 3 executables in the WPS top-level directory, that are linked to their corresponding src/ directories:
```bash
geogrid.exe -> geogrid/src/geogrid.exe
ungrib.exe -> ungrib/src/ungrib.exe
metgrid.exe -> metgrid/src/metgrid.exe- Download the benchmark dataset, here is the website for dataset: https://www2.mmm.ucar.edu/wrf/users/benchmark/v44/benchdata_v44.html Choose one of them for testing. Unzip the file. copy the wrfbdy_d01, wrfinput_d01 and namelist.input file to WRF/test/em_real file.
change the namelist.input file
The ADIOS2 I/O option for history and/or restart file is enabled by setting one of the following:
io_form_history = 14
io_form_restart = 14
frames_per_outfile = 1000000,
history_outname = '/Path/to/output/wrfout_d<domain>_<date>',
Do not change the wrfout_d<domain>_<date>
Run wrf with adios2 add adios2.xml file in the same folder(wrf/test/em_real) Here is the example of adios2.xml file:
<?xml version="1.0"?>
<adios-config>
<!-- <io name="wrfout_d01_2018-06-17_00:00:00"> -->
