-Viper Open OnDemand is a web portal that provides a single access point to a full range of ways to make use of Viper. Currently, Viper Open OnDemand is only available on the University network, so you must be on campus or connected via VPN. In the future, it is anticipated that it will be made accessible from off campus network with Multi-Factor Authentication (MFA).
+Viper OnDemand is a web portal that provides a single access point to a full range of ways to make use of Viper.  Viper OnDemand provides access to your HPC file storage, allows you to prepare, submit and monitor batch jobs, and also allows you to run a range of interactive graphical applications directly on Viper HPC hardware.
