Creating a PI Account

Johns Hopkins Principal Investigators (PIs) may request projects and resource allocations using the Coldfront Portal. Once an allocation is approved, users may request accounts. PIs or their designated proxies are responsible for adding users to the appropriate allocations once it is created.

Key features of the portal include:

  • Requesting new projects and allocations (PIs)

  • Managing users and adding them to allocations

  • Uploading publications, grants, and ROI reports

  • Assigning proxy account managers

  • Monitoring usage across groups and allocations

Warning

Allocations are reset quarterly under a “use it or lose it” model. Unused core-hours do not carry over.

Note

By requesting an account on Rockfish, you are automatically subscribed to the Rockfish Users mailing list: rockfishusers@lists.jh.edu. This list is used to distribute important cluster announcements, including scheduled maintenance, outages, and policy updates.

Unsubscribing from this mailing list will result in account deactivation, as it is the primary channel for operational communication.

Note

All users should review the Rockfish Citizen guidelines before requesting an allocation or account.

Getting Started

When you first navigate to the Coldfront Portal, you’ll be prompted to log in or create an account. PIs should click Request Allocation (only for PIs).

Coldfront login page

You will then be asked to enter your JHED ID (as your username), email address, and a password. Important: You must use your JHED ID. Using anything else will delay access and break services such as Globus.

Coldfront create account form

After submitting your request, you should see a confirmation message. You can then log in with your new credentials.

Creating a Project

Once PI status is approved, you can create a project:

  1. From the top menu, select Project → Add a Project.

  2. Fill out the project form with a clear title and detailed description.

Coldfront add project

In the description, include:

  • Scientific or academic goals

  • The type of computations or analyses you expect to run

  • Resource requirements (cores, GPUs, storage)

  • Anticipated outcomes (e.g., publications, presentations, deliverables)

This information helps administrators allocate resources appropriately.

Adding Users

With a project and allocation in place, you can add users:

  1. Click Add Users on the project page.

  2. Search by JHED ID. Users must have already created an account in the Coldfront Portal to appear.

Coldfront add users

Select the users to add. Accounts are not active on the cluster until this step is completed. You may also assign certain users as Managers, giving them rights to manage other users within the project.
