# Open OnDemand

Open OnDemand is a web portal that provides access to ARC HPC clusters. It facilitates clusters’ access and job management without the need for Linux experience or any installations on the client-side. The only requirement is an up-to-date web browser. Firefox or Chrome are preferred.

## Features
OnDemand provides the following features

- File Management and Transfer
- Job Management
- Shell Access
- Interactive Apps

## Usage instructions

- In order to use OnDemand, you will need to be using the university network or on VPN (VT Traffic over SSL VPN)
- Once connected, go to either:
  - <https://ondemand.arc.vt.edu> (Legacy site: Older version)
  - <https://ood.arc.vt.edu> (New site: Newer version and features, but still under development in places)
- Then, you can log in using your VT credentials (PID and password). If already logged into another VT site, you may not need to enter any credentials at all.

## Examples

OnDemand provides interactive apps on each of the clusters, as shown in the image below.
