Containerization is also increasingly popular in HPC it provides isolated environments that allow for the reuse of images for better reproducibility and software portability without the performance impact of other methods or the hastle of manualy installing dependencies. Containers are run using Apptainer (formerly Singularity), a containerization platform similar to Docker with the major difference that it runs under user privileges instead of `root`. Users can deploy images from NGC (NVIDIA GPU Cloud), which provides access to a wide array of pre-built images with GPU-optimized software for diverse applications. Leveraging container images can save a lot of time as users don’t need to set up the software applications from scratch and can just pull and use the NGC images with Apptainer.

## Login node
Access to the cluster is provided through SSH access to the login node. The login node serves as the gateway or entry point to the cluster. Note that most software tools are not available on the login node and it is not for prototyping, building software, or running computationally intensive tasks itself. Instead, the login node is specifically for accessing the cluster and performing only very basic tasks, such as copying and moving files, submitting jobs, and checking the status of existing jobs. For development tasks, you would use one of the development nodes, which are accessed the same way as the large compute nodes. The compute nodes are where all the actual computational work is performed. They are accessed by launching jobs through Slurm with `sbatch` or `srun`.

### Connection and credentials
Access to the cluster is provided through SSH to the login node. Upon your account's creation, you can access the login node using the address provided in your welcome Email.
If you have existing Linux lab credentials, use them to log in. Otherwise, login credentials will be provided to you.
Additionally, Binary provides access to your Linux lab files, **But not that** Binary is **not** just another Linux lab machine. It simply provides mutual features (e.g., credentials) for convenience.
