If you are using a resource manager job scheduler , you are likely creating a script that requests the resources and runs the application. In this case, you might need to load the correct Environment Modules in your script. Typically after the part of the script in which you request resources in the PBS world, these are defined as PBS commands , you will then load the environment modules you need.

As root, run the following commands:. Before you start configuring and building the code, you need to fulfill a few prerequisites. First, you should have Tcl installed, as well as the Tcl Development package. At this point, you should configure and build Environment Modules. As root, enter the following commands:. The next thing to do is copy one possibly more of the init files for Environment Modules to a global location for all users. For my particular cluster, I chose to use the sh init file.
