How should I acknowledge the OLCF in my publications and presentations?

Users should acknowledge the OLCF in all publications and presentations that speak to work performed on OLCF resources:

This research used resources of the Oak Ridge Leadership Computing Facility at the Oak Ridge National Laboratory, which is supported by the Office of Science of the U.S. Department of Energy under Contract No. DE-AC05-00OR22725.

What is a subproject?

Many OLCF projects make use of optional subprojects. Subprojects provide a useful means for

  • dividing allocations among different applications, groups, or individuals
  • controlling priority
  • monitoring progress

Similar to individual user accounts being granted resources by their association with a project, individual user accounts are granted the resources of a subproject upon association with the subproject.

Note: Subprojects do not inherit the accesses of their primary projects, and users can be associated with a subproject without association with the primary project.

The ID for a subproject must follow the format of:
<6 character primary project ID> + <1-4 character subproject suffix>.
For example, project ABC123 could have subprojects ABC123XYZ6 and ABC123P3.

The hours allocated for the primary project and subprojects must equal the awarded allocation. All hours can be allocated to subprojects, or some amount can be held as reserve as part of the primary project. It is recommended that all users be assigned to a subproject(s). If all of a primary project’s awarded hours are allocated to its subprojects, all primary project users must be associated with a subproject(s).

If you have any questions, or would like to request a subproject, please contact the OLCF Accounts Team at

Note: Subprojects are created at the request of project PIs.

I no longer need my account. Who should I inform and what should I do with my OLCF issued RSA SecurID token?

Please inform the Accounts Team via email at and return the RSA SecurID Token to the following address:
