Environment Modules
Several software packages on the cluster require correct definition of certain environment variables. These variables establish the package's configuration and influence its behavior. For example, PATH and LD_LIBRARY_PATH specify the location of package binary files.
Environment Modules is a tool to manage package environment variables.
With simple command line options, you can prepare the environment for any package available on the cluster. In the case of packages with multiple versions, there are options to switch between one version and another - defining and undefining variables as needed. If there is a conflict between two packages, module will alert you.
