Lmod is the modern Environment Module Tool. Sysadmins define packages and let users choice which package and which version of that package. This part of the talk will include a brief overview of Lmod. This will be followed up with the new features such as extensions for connecting modules to packages. (e.g. the python module and packages such as numpy and scipy). This is also include a discussion of the changes to Lmod 8+.

XALT is a tool to take the census of what programs and libraries are run on your cluster. This talk will briefly cover what XALT does and how it does it. It will include some "war" stories of XALT usage. Finally I'll cover XALT move to version 3 namely tracking usage in containers and package tracking from R, Python and MATLAB.
