OSC has a job opening on the Open OnDemand team!

Full details are available here:


Open OnDemand is an NSF-funded open-source HPC portal based on OSC’s original OnDemand portal. The goal of Open OnDemand is to provide an easy way for system administrators to provide web access to their HPC resources, including, but not limited to:

See the documentation for installation directions, app development tutorials, and an overview of the components and applications that make up OnDemand. We also have a walkthrough video showing the various components of an Open OnDemand instance available.

Organizations using or exploring OnDemand

Below is a list of organizations that have deployed or are looking at deploying Open OnDemand. Please contact us via the news list if your organization is not on this list and should be included!

We also have a page with testimonial comments from many of these organizations

Run your own live demo

There are 2 ways you can have a demo Open OnDemand instance running in minutes:

  1. Using Vagrant. Just follow the steps listed in the ood-images-full README.

Collaborating with Open OnDemand

The Open OnDemand team welcomes and encourages opportunities to collaborate on proposals with members of our community in response a variety of solicitations. Examples of potential collaboration roles our team can have include developing and delivering related client education and training programs, and providing extended support services for software deployment and custom workflow development. Please contact us via the news list if you would like to discuss a potential collaboration.

Please consider contributing to the code repository on Github. Since January 2016 there have been over 8,000 commits to the code base, but we can always use additional development help!

Project Cybersecurity

Trusted CI , the NSF Cybersecurity Center of Excellence conducted an in-depth vulnerability assessment of Open OnDemand, completing it in December 2018. This assessment included a careful review of the code, increasing our confidence in its security. The Ohio Supercomputing Center addressed the implementation issues (bugs) that were found during this review, producing a more robust revision of Open OnDemand.

If you have security concerns or think you have found a vulnerability in Open OnDemand, please contact us directly via email on the news list linked above.
