OnDemand
Open OnDemand (OOD)
Open OnDemand ("OOD") is a web-based service provided by GACRC which provides users an alternative and/or complimentary method to access the HPC Clusters. It helps computational researchers and students efficiently utilize remote computing resources by making them easy to access from any device, via a convenient web interface. Through Open OnDemand, graphical applications can be utilized on the cluster far more easily and smoothly than using X11 Forwarding. It also helps computer center staff support a wide range of clients by simplifying the user interface and experience.
OOD Features:
- Job submission and monitoring
- File transfer and management
- File editing
- Shell access
- Graphical Desktop on the cluster
- Interactive Applications

Browser Requirements/Notes
To have the best experience using OnDemand, use the latest versions of Google Chrome, Mozilla Firefox or Microsoft Edge. Use any modern browser that supports ECMAScript 2016. Google Chrome has the widest range of support since the Shell App uses hterm.js which is supported officially by Google. Chrome currently is the only web browser that natively supports the copy and paste functionality in noVNC. Other browsers can do copy and pasting manually through the noVNC tool drawer. Safari users may have issues when using the Shell App or noVNC. There is no IE 11 support.

Additional Notes
Per User Experience
OnDemand will spawn a Per User Nginx session upon successful login. This means that each connection on the OOD server is running as that particular user. Each session is completely separated from other users sessions.
