Open OnDemand has been configure at WVU to access computational resources on Thorny Flat, the biggest cluster at WVU.

In order to access Open OnDemand you should be in-campus network. Try to access it on you browser:

https://ondemand-tf.hpc.wvu.edu

You should get a page asking for authentication, like below.
