Open OnDemand is an intuitive, innovative, and interactive interface to remote computing resources. The key benefit for SCINet users is that they can use any web browser, including browsers on a mobile phone, to access Ceres.
There are several interactive apps that can be run in Open OnDemand including Jupyter, RStudio Server, Geneious, CLC Genomics Workbench, and more. The desktop app allows a user to run any GUI software.
