Apply for computer accounts at AFs¶
The BNL Analysis Facility (AF) currently requires users to register for a computing account.
The registration process differs depending on whether you are currently an ATLAS collaborator or not.
If you already have an account, you may skip this section.
- Existing ATLAS collaborators are encouraged to apply for a full SCDF account.
- All other users should apply for a Federated Identity account.
As the AF continues to develop, the account registration process will be streamlined and unified for all users.
Brookhaven National Lab¶
Brookhaven National Lab has two types of accounts:
| Federated Identity account | Full SCDF account | |
|---|---|---|
| JupyterHub access | Yes | Yes |
| SSH to interactive nodes | No | Yes |
| Direct HTCondor submission | No | Yes |
| Batch compute | Indirectly — HTC Jupyter sessions run as HTCondor jobs | Yes, directly |
| Typical time to obtain | 1–2 business days | Longer — requires Guest/Life number and training |
Select FCC on the application form
For either account type, select FCC as your experiment on the application form. That is what puts you in the group_usfcc accounting group, which your batch jobs and HTC Jupyter sessions run against. There is no separate request to make afterwards.
Federated Identity Account¶
The Federated Identity account is quicker to obtain. Users reach BNL AF resources only through the JupyterHub instance — it does not provide SSH access to the interactive nodes or direct HTCondor submission. Note that sessions started on the HTC JupyterHub do run as HTCondor batch jobs, so you still get batch compute through Jupyter.

Full SCDF Account¶
The main site for new user sign-up for a full SCDF account is here: BNL New User Account
Applying for a BNL computing account is a multi-step process. You will need to go through the following steps:
- Register for a Guest Number (if you don't already have a valid Life or Guest Number) - visit the BNL GUV center
- Same for as if you were going to visit BNL campus
- Most likely will need to upload photos of identification
- Non-citizens will need to upload your CV
- Complete CyberSecurity training and Computer Use agreement
- Sign up for a New User Account
- Complete directly on the BNL New User Account site above
