Open OnDemand

Open OnDemand is a web portal for HPC users. They sign in from a browser and open JupyterLab, RStudio, VS Code, a desktop or a shell, and submit batch jobs. The Open OnDemand Service runs it on OpenNebula as a OneFlow service from the Community Marketplace, with its own Slurm cluster inside. Every session is a Slurm job on a pool of compute VMs that grows and shrinks with the queue.
