OnDemand

Open OnDemand (OOD)

Open OnDemand 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 Graphical User Interfaces.
• It helps computer center staff support a wide range of clients by simplifying the user interface and experience.

Throughout this documentation, the Open OnDemand application may be referenced by the acronym "OOD".

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.

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.
