As mentioned in Section 4.1, “Introduction”, the first step in working with SMOKE is invoking the Assigns file. In this section, we will go beyond that first step to actually running the scripts. In the first section, we describe how to run the nctox case, previously described. But first, we will review the essential steps for running SMOKE each and every time you start to work with the SMOKE system.

First, the EDSS_ROOT environment variable needs to be defined. In Section 12.3, “Installing SMOKE”, we explain that you can configure your UNIX system to set this automatically each time you log into your computer. If you have not done that, then you will need to set the EDSS_ROOT variable manually before invoking an Assigns file:

setenv EDSS_ROOT <directory in which you installed SMOKE>

Second, you must invoke the Assigns file for the case that you want to run. This will make available all of the environment variables that you can use to navigate through the SMOKE directory structure. There is a different Assigns file for each case, so we provide this instruction with the case-specific documentation below. Of course, when you develop an Assigns file for your case, you will use that instead.
