There are a few methods for connecting to the supercomputer; each has their advantages and disadvantages. Connecting to the Supercomputer with SSH Using SSH from the shell (also called the terminal) is the most versatile method, though it tends to be slower with interactive graphical applications. If you intend to use applications that rely on a point-and-click interface, we recommend the web portal “Aloe Desktop” for these cases. Our webportal has become the standard for new users, as it provides a file system viewer and editor, a job submission tool, the ability to view the job queue, and a zoo of interactive applications including a virtual desktop, Jupyter Lab, like JupyterLab, and RStudio. In the file manager, uploading files is as easy as dragging-and-dropping through the interface! This document also assumes you already have requested and been granted an account.

Quick Start
For users who have never used any HPC environment before, we would recommend reading through the detailed start.
For those who wish to get started quickly, here is the general overview:
Choose a connection method (ssh / Webportal)
Connect to the ASU VPN
Transfer files as needed
Log in with your WINEDS username & password
Run an interactive session or create an SBATCH script

...
Login Node: A node intended as a launching point to compute nodes. Login nodes have minimal resources and should not be used for any application that consumes a lot of CPU or memory. Also known as a head node.
...
Compute Node: Nodes intended for heavy compute. This is where all heavy processing should be done
...
HPC: Short for “High Performance Computing” it refers to a group (cluster) of computers designed for parallelism across many computers at once. Publicly these are often called “supercomputers”
...
Cluster: A group of interconnected computers that can work cooperatively or independently.
...
Job: Work assigned to be done on a compute node. Any time a compute node is assigned a job is created.
...
Scheduler: The application on our end that assigns compute resources for jobs.
