How to Apply for an RCC Account

Discovering the world of high-performance computing at RCC is as easy as pie! We've streamlined the account application process into two main categories: Principal Investigator (PI) accounts and General User accounts. If you're a course instructor, we've got you covered with the option to apply for an Education account.

Principal Investigator (PI) Accounts

Since October 2018, distinguished academics with titles like professor, associate professor, assistant professor, and more are eligible to dive into the wonders of RCC with a PI account.

General User Accounts

Everyone else, from graduate students to external collaborators, can grab an RCC general user account. Just keep in mind, a PI with an active RCC account must be your sponsor.

Education Accounts

Instructors aiming to bring the power of RCC clusters to their courses can apply for an RCC Education account quarterly using the provided form.

Note: Instructors can request to carry course materials over to the next quarter or academic year by contacting

Will I still have access to my RCC account after leaving the University?

Typically, UChicago IT will terminate your CNetID a few months after you leave. To keey using Midway clusters, request an RCC account extension.

What to Do After Completing a Project

Once your project is complete, it's essential to ensure smooth handover and file management. Follow these steps:

  1. Grant Group Access: Allow your group members access to your files using the following SSH command:

    chmod 2771 -R <your_folders>

    For example:

    chmod 2771 -R /project/drpepper/cell-tracker

    This command sets the appropriate permissions for your folders.

  2. Assign Group Ownership: Ensure that your account's PI is the group owner of your files with:

    chgrp pi-drpepper -R <your_folders>

    For example:

    chgrp pi-drpepper -R /project/drpepper/cell-tracker

    This step facilitates proper file management within your research group.
