Getting Started
1. Clone the WRF Git
For 4.0 Branch use:
| Code Block | ||
|---|---|---|
| ||
$ git clone https://github.com/wrf-model/WRF.git
... |
For 3.9.1.1 branch use
| Code Block |
|---|
$ git clone --branch V3.9.1.1 https://github.com/NCAR/WRFV3.git
... |
2. Load prerequisite modules
...
| Code Block |
|---|
$ export WRFIO_NCD_LARGE_FILE_SUPPORT=1 $ export NETCDF=$NETCDF_DIR |
4. Configure
| Code Block |
|---|
./configure |
There are 4 ways to configure for any given platform (one per line, see below)
serial - to be run on single processor
smpar - to be run with OpenMP on a single node
dmpar - to be run with MPI over one or more nodes.
dm+sm - to be run hybrid with OpenMP and MPI
...
NotesYou need to choose the desired build from the menu (e.g. 66 for Intel broadwell) and choose the domain nesting option (e.g. 1)
The nesting options as as follows:
basic: any nested domains are fixed (default)
preset moves: nested domain may move according to fixed parameters
vortex-following: For hurricane model forecasting

Will use NETCDF in dir: /global/software/centos-7/modules/intel/2019.1.144/netcdf/4.6.2-hpcx-2.4.0
HDF5 not set in environment. Will configure WRF for use without.
PHDF5 not set in environment. Will configure WRF for use without.
Will use 'time' to report timing information
$JASPERLIB or $JASPERINC not found in environment, configuring to build without grib2 I/O...

After the configure, you may edit the configure.wrf file to adjust as needed.
For example:
-xHost will not work on AMD
AVX2 may need to change to AVx512
...
remove
...
for Intel Skylake hosts
Edit mpicc, remove the “-f90=$(SFC)” option from mpif90 and the “-cc=$(SCC)” option from mpicc
...
for HPC-X (Open MPI) as it doesn’t need those options

5. Compile
| Code Block |
|---|
./compile wrf |
6. Check the run directory
For input, make sure you have
Input file: wrfinput_d0* (at least 1) or wrfrst*
wrfbdy_d0* (at least 1)
namelist.input
7. Check the progress by running tail -f on rsl.out.0000
In this example, we can see that every 15 seconds or weather forecast, takes about 1.7 seconds.

$ tail -f rsl.out.0000
