 ### 1.2 Local testing
 Follow the step-by-step guide in [How to add experiments to a buildbot list :material-open-in-new:](https://gitlab.dkrz.de/icon/wiki/-/wikis/How-to-setup-new-test-experiments-for-buildbot#how-to-add-experiments-to-a-buildbot-list){:target="_blank"} to add you experiment test case. Start with the `checksuite_modes` for the mpi and nproma test (`'nm'`) for the machine you are testing on.

 #### Test on CPU
-To ensure that there are no basic issues with the namelist, we recommend to start testing on CPU before going over to GPU testing.

 #### Test on GPU
-If all tests are validating on CPU, the next step is to test on GPU. First, compile icon-nwp on GPU. Then create the check file and run the mpi and nproma test locally as above. If those tests also validate on GPU, you can continue with the tolerance test to ensure that running on GPU gives basically the same results as running on CPU. Therefore, change the `checksuite_mode` to `'t'` for the tolerance test and follow the instructions in [Validating with probtest without buildbot references (Generating tolerances for non standard tests) :material-open-in-new:](https://gitlab.dkrz.de/icon/wiki/-/wikis/GPU-development/Validating-with-probtest-without-buildbot-references-(Generating-tolerances-for-non-standard-tests){:target="_blank"}).
