Connecting Computing Power With Powerful Minds
Open OnDemand is an easy-to-use web portal that lets students, researchers, and industry professionals compute from anywhere. By eliminating the need for client software or command-line interface, Open OnDemand empowers users of all skill levels and significantly speeds up the time to their first computing job.
Benefits for users
Instead of going to the lab or installing client software, users can access supercomputers through the web. They can compute from anywhere, on any device, regardless of skill level.
Benefits for admins
Admins can expand supercomputer usage throughout their organization. By providing remote web access, they can optimize resources and better serve students, researchers, clients, and colleagues.
System Requirements
Here are the software and hardware requirements for installing Open OnDemand.
Software requirements

- TurboVNC 2.1+
- websockify 0.8.0+
Hardware requirements (minimum)
- 16 cores
- 64GB RAM
- 150MB memory
Security Evaluation
We want to ensure your organization and users are protected. Below is an overview of Open OnDemand’s security, as well as measures we’ve taken to strengthen it.
Since launching Open OnDemand, we’ve completed two engagements with Trusted CI, the NSF Cybersecurity Center of Excellence. The first engagement, completed in December 2018, involved an in-depth vulnerability assessment and careful code review. Trusted CI identified a few implementation issues, or bugs, which we have since addressed.
In January 2021, we began a second engagement to meet three objectives: 1) integrate security automation into DevOps flows; 2) transfer skills for vulnerability assessments; and 3) develop needed security policies, practices, and procedures. Trusted CI issued another report after the engagement.
Thanks to these engagements, Open OnDemand is now a more robust and secure portal. Our team is better positioned with regards to security dev ops, and we have greater confidence in our code.
If you have a security concern or have found a vulnerability in Open OnDemand, please let us know.
