Logging In

Stella cluster runs AlmaLinux 9.4, a popular enterprise-grade Linux distribution optimized for stability and high-performance computing (HPC) workloads. While the primary way to interact with an HPC cluster is through a text-based command-line interface, some applications also support graphical interfaces.

The only method available for logging into the cluster is through the Secure Shell (SSH) protocol ssh. To connect, you must have an SSH client or terminal installed on your system..

Both Linux and macOS come with terminals that contain an ssh command-line client. Windows 10 and above support ssh from the Windows terminal. For older versions, users can either install the Windows Subsystem for Linux to have a similar experience or install a standalone application such as PuTTY.

If you are new to the Linux/Unix world, it is highly recommended that you quickly get acquainted with the usage of a shell such as bash, as it is a prerequisite to using any modern HPC cluster. A good tutorial on this subject can be found here.

Use the following command to access the Stella login node:

# Stella login
    ssh ACCESSNETID@stella.hpc.temple.edu

ssh will prompt you for your AccessNet password. Once logged in successfully, you will see the following shell prompt:

    :'######::'########:'########:'##:::::::'##::::::::::'###::::
    '##... ##:... ##..:: ##.....:: ##::::::: ##:::::::::'## ##:::
     ##:::..::::: ##:::: ##::::::: ##::::::: ##::::::::'##:. ##::
