CCR OnDemand is an easy to use web-based portal that provides users access to CCR's HPC resources without the need to install additional client software or web-plugins. Users can transfer files, access a shell environment on the cluster front-end login server, launch interactive and remote visualization sessions, and monitor jobs.
NOTICE: This product is an open source project developed by Ohio Supercomputer Center and is currently in a beta test mode at CCR. Please provide feedback via our help portal if you have questions, suggestions or encounter any problems. We appreciate your patience during this test period.
Using your UB username, login to the CCR OnDemand portal:
Enter your CCR password and the answer to your security question:
|Do you have two-factor authentication enabled?|
If so, you will need to enter your one-time token (OTP) generated from your mobile app.

You will now be asked to give your consent to the CCR OnDemand application to access resources on the server. Click the green Approve button:
Once logged in you are presented with the CCR OnDemand dashboard:
Files - Home Directory
Users can easily transfer files to or from their local computers using this File Explorer app. You can also edit files directly using the "Edit" button. This application is provided as is and support is not provided by CCR unless there is an error. Documentation on the app is not provided other than to mention a few caveats:
- Do NOT transfer large files or large amounts of file using this method. Using sftp to one of our front end servers. Details on the transfer server are here
- File transfer is limited to the amount of memory on the OnDemand server and the number of users currently using it. If you get errors, please report them to CCR help.
Your Jobs - Users can view all jobs running through OnDemand and view details of their own jobs:
Click on the job to see more details about it:
All Jobs: You will see all jobs currently running and queued in the ub-hpc cluster. You can sort by Status (running or queued), by Queue (general-compute, viz, debug, largemem), as well as by user, account, job ID and job name.
Detailed documentation on the jobs and templates apps is coming soon! Thank you for your patience.
UB HPC Shell Access: This app provides users with a command-line tool to access the UB-HPC (academic) cluster front-end server. No need to install a SSH client like PuTTy!
This is a terminal window and where you will type all of your commands. If you are unfamiliar with UNIX commands, we recommend you view the following articles:
