Environment Modules are an indispensable tool for high-performance computing that allow you to switch between and among versions of compilers, libraries, and applications.

The indispensable Lmod high-performance computing tool allows users to control their build and execution environment.

Lmod is an indispensable tool for high-performance computing. With the new release of version 6, now is a good time to review Lmod and look at its new capabilities.

The Modules package makes life easier in the HPC world (and beyond).

Gathering data on various aspects of your HPC system is a key step toward developing information about the system and one of the first steps toward tuning your system for performance and reporting on system use. It can tell how users are using the system and, at a high level, what they are doing. In this article, I present a method for gathering data on how users are using Environment Modules, such as which modules are being used, how often, and so on.

Sooner or later, every cluster develops a plethora of tools and libraries for applications or for building applications. Often the applications or tools need different compilers or different MPI libraries, so how do you handle situations in which you need to change tool sets or applications? You can do it the hard way, or you can do it the easy way with Environment Modules.
