Notes on compiling and running on NCAR's Yellowstone System

To log-in to Yellowstone, type the following:

        ssh -Y

You will use your Yubikey or cryto-card when prompted (this will be the same code as you used with Bluefire)

**We do not recommend that you try to implement your own .login, .cshrc, etc. files until you are very familiar with the Yellowstone system. Yellowstone provides several modules that you can use to change some of your settings. For a more detailed description of the Yellowstone system, please click here.
For specific details about modules, please click here.

**Note: When you first log-in to Yellowstone, the default compiler will be Intel. If you wish to change this, please see the above link for directions on using modules to make modifications.

If you are not changing the code, pre-compiled WRFV3 and WPS code is available on Yellowstone. This can be found in the ~wrfhelp/PRE_COMPILED/ directory (this includes all executables for WPS and WRFV3, as well as utilities, which are found under WPS/util). The following options are available:

WRF-ARW Available Pre-Compiled Code

3.8.1 Intel dmpar 15
3.8 Intel dmpar 15
3.7.1 Intel dmpar 15
3.7 Intel dmpar 15
3.6.1 Intel dmpar 15
3.6 Intel dmpar 15
3.5.1 Intel dmpar 28
3.5 PGI dmpar 19
3.4.1 PGI dmpar 3
3.4.1 Intel dmpar 15
3.4 PGI dmpar 3
3.3.1 PGI dmpar 3
3.3 PGI dmpar 3
3.2.1 PGI dmpar 3
3.2 PGI dmpar 3

**All versions of WRFV3 are compiled with the basic nesting option (option #1), and beginning with version 3.5, they are compiile with large file support.**

WPS Available Pre-Compiled Code

3.8.1 Intel serial 17
3.8 Intel serial 17
3.7.1 Intel serial 17
3.7 Intel serial 17
3.6.1 Intel serial 17
3.6 Intel serial 17
3.5.1 Intel serial 17
3.5 Intel serial 17
3.4.1 PGI serial 5
3.4 PGI serial 1
3.3.1 PGI serial 10
3.3 PGI serial 10
3.2.1 PGI serial 6
3.2 PGI serial 6

**All versions of WPS are compiled with the option of using Grib1 and Grib2 input data.**

Static input data for running geogrid.exe are available in ~wrfhelp/WPS_GEOG. You will need to specify this path in namelist.wps

You will need additional libraries to run/compile ungrib.exe. You can find these libraries in ~wrfhelp/UNGRIB_LIBRARIES. You will need to add these to set your environment to point to these libraries. For example, if you are using csh or tsch:

        setenv JASPERLIB /glade/u/home/wrfhelp/UNGRIB_LIBRARIES/lib
        setenv JASPERINC /glade/u/home/wrfhelp/UNGRIB_LIBRARIES/include

Batch job scripts can be found on Yellowstone under ~wrfhelp/BATCH_SCRIPTS. Make sure the project number is correctly set in the script (if you were granted a project number prior to using Yellowstone, you will need to put a 'P' in front of your 8-digit number). To submit a job in the queue, type:

        bsub < my-script.csh


Various versions of source code can be found on Yellowstone, in ~wrfhelp/SOURCE_CODE


If you plan to use NCL, you can load it by typing:

        module load ncl

If you plan to use ncview, you can load it by typing:

        module load ncview
