Environment Modules

Environment Modules let you dynamically load and unload software packages without conflicts between versions. Always load the modules your job needs before running it.
Common Commands
Finding Modules
# List all available modules
module avail
# Search for a specific module
module avail gcc
# Get detailed info including dependencies
module spider gcc/gcc-12.1.0
Loading and Unloading
# Load a module
module load gcc/gcc-12.1.0
# List currently loaded modules
module list
# Unload a specific module
module unload gcc/gcc-12.1.0
# Unload all modules
module purge
Inspecting a Module
# See what environment variables a module will set
module show gcc/gcc-12.1.0
In Job Scripts
Load modules inside your job script, after the 
#SBATCH directives:
#!/bin/bash
#SBATCH --job-name=my_job
#SBATCH ...
module purge
module load gcc/gcc-12.1.0
./my_program
Starting with 
module purge ensures your job is not affected by any modules loaded in your shell session.
