Open OnDemand Web Portal

Open OnDemand (OOD) provides access to the HPC and filesystems through your web browser. This is the recommended way of using the HPC for graphical applications (Jupyter Notebook, VisIt, etc.).

OOD It allows you to view, edit, upload and download files, create, edit, submit and monitor jobs, run GUI applications, and connect to the terminal, all via a web browser and with a minimal knowledge of Linux and scheduler commands.

Features#

Open OnDemand is an ongoing NSF-funded project developed at the Ohio Supercomputer Center. Its aim is to provide an easy way for system administrators to provide web browser access for users to their HPC resources.
