HPC systems are usually accessed via a Linux-based Command Line Interface (CLI). Via the CLI, users can run programs to manipulate files, load additional software, or execute programs. While there are many similarities to single-user Linux systems, HPC systems differ widely in the management of provided Software packages, and users must pay attention to the locality of data.

To access and manipulate data. To execute programs in a cluster environment.
