HPC maintains software, compilers, and libraries in the directory /public/software and /datadir1/software.

To access much of the software available on the AP cluster - ranging from compilers and interpreters to statistical analysis and visualization software, and much more - you’ll need to set ENVs by yourself according to the Load section.

We’ll use Environment Modules to manage softwares soon. It’ll be much easier and more convenient …
Anyway, it’s better to understand ENVs before using module.
